Patent Application
20230112431
PCR (polymerase chain reaction) diagnostic testing for various illnesses may be desirable for a number of reasons. Typical PCR tests (e.g., for COVID-19 testing) require that a sample be collected from a person via a nasal swab or saliva, and then the collected sample is transported to a lab, where the sample is processed and placed into a 96-well plate for high volume PCR testing. However, such PCR testing may be cumbersome, time consuming, and require a centralized lab setup. Systems and methods for rapid PCR testing at a local (e.g., point of care) site may therefore be desired.
The detailed description is set forth with reference to the accompanying drawings. The drawings are provided for purposes of illustration only and merely depict example embodiments of the disclosure. The drawings are provided to facilitate understanding of the disclosure and shall not be deemed to limit the breadth, scope, or applicability of the disclosure. The use of the same reference numerals indicates similar, but not necessarily the same or identical components. Different reference numerals may be used to identify similar components. Various embodiments may utilize elements or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. The use of singular terminology to describe a component or element may, depending on the context, encompass a plural number of such components or elements and vice versa.
Embodiments of the present disclosure include systems and methods for rapid, local PCR testing. To facilitate this, a local testing module including a PCR configured for use in these systems and methods has been developed.
In embodiments, the testing module may include a housing having a PCR machine disposed therein; an input station on the cabinet, wherein the input station is configured to receive a sample collection device (SCD) comprising a biological specimen sample; a SCD processing mechanism configured to transfer, without human intervention, a lysed microportion of the biological specimen sample into a PCR sample tube; at least one mechanism configured to transfer the PCR sample tube to the PCR machine; and a controller configured to cause the PCR machine to (i) conduct a PCR test on contents of the PCR sample tube, and (ii) generate results of the PCR test.
In particular embodiments, the testing module may be used to diagnose a particular illness, for example at a point of care site or other locations. The testing module may be a portable PCR testing module. In embodiments, the testing module performs a PCR test on a sample collected by a sample collection device (SCD) used in conjunction with the testing module. The SCD may be configured for collecting a saliva specimen from the mouth of a patient, or for collecting a nasal mid-turbinate (NMT) specimen, or anterior nasal specimen, from a nostril of a patient. The patient may be a human. The sample may also be collected from an object. These collections may be self-administered by a patient following collection instructions or performed by a trained healthcare provider. The sample collection device may be configured for collecting other biological fluids from a human or non-human mammal. The collected specimen may be referred to herein as a “sample”. In embodiments, the sample is placed into the testing module by a patient or other user following instructions or by a trained healthcare provider.
The SCD includes at least a swab and a sample container. In some embodiments, the SCD provided to the testing module may include an attached PCR sample tube. For example, the SCD provided to the patient for receiving the biological specimen may include a SCD having a pre-attached PCR sample tube. In other embodiments, the SCD provided to the testing module may have no PCR sample tube. In those embodiments, the testing module may include mechanisms configured to retrieve a PCR sample tube from a storage rack or other source within the housing and configured to attach the PCR sample tube to the SCD following receipt of the SCD by the testing module. In an alternative embodiment, the PCR sample tube and/or a sample container portion of the containing the biological specimen sample may be separated from the SCD or from the swab, respectively, prior to the sample being deposited in the testing module.
Once the sample is inserted in the testing module, the testing module will extract the biological specimen sample, lyse it, mix it with water and appropriate reagents (e.g., a lyophilized master mix) and present this mixture in a PCR sample tube, which in particular embodiments is attached to the SCD. The sample tube is then processed in a PCR machine contained within the testing module. In some embodiments, the testing module is configured to test multiple samples in parallel or simultaneously. In some embodiments, the testing module can test up to 200 samples simultaneously. In embodiments, the testing module inactivates the sample to render it non-infectious before testing it. In some embodiments, the testing module includes a continuous PCR system.
In some embodiments, the PCR machine performs a PCR test on the sample to amplify genetic material of interest. It is understood that any method known in the art for amplifying genetic material may be used, including standard PCR, qPCR, RT-PCR, RT-qPCR, and hot start PCR. In embodiments, the testing module may have more than one PCR machine, and be able to perform more than one type of PCR. In some embodiments, the PCR machine runs a PCR test of the PCR sample tube contents to determine whether the lysed biological fluid sample includes a particular RNA, such as one indicative of a particular pathogen. For example, the RNA may be one indicative of the SARS-CoV-2 virus. Accordingly, the test module may generate PCR test results that enable diagnosis of one or more particular diseases or illnesses.
The testing modules described herein facilitate rapid PCR testing at a point of care site or other locations of convenience to patients, office workers, travelers, etc. In embodiments, the testing module comprises one or more displays presenting a user interfaces, e.g., with buttons and/or an interactive screen.

One or more illustrative embodiments of the disclosure have been described above. The above-described embodiments are merely illustrative of the scope of this disclosure and are not intended to be limiting in any way. Accordingly, variations, modifications, and equivalents of the embodiments disclosed herein are also within the scope of this disclosure. The above-described embodiments and additional and/or alternative embodiments of the disclosure will be described in detail hereinafter through reference to the accompanying drawings.
In some embodiments, the testing module is located at a point of care site such as an office building, medical facility, or other commercial building.
The testing module includes a housing, or main cabinet, 114 which comprises an enclosure for PCR machines 106. The testing module 100 may include one or more patient interfaces 102 for the user/patient to use the testing module. The user interface 102 may comprise an interactive screen. The user interface 102 may assist the user in various ways, including but not limited to providing instruction to the user, accepting payment for the test, identification of the user, and/or output of test results, including prior test results. Some or all of these user interface functions may alternatively or additionally be provided to the user via email, text message, app or webpage.
The PCR testing module 100 includes one or more sample input stations 104 for receiving the SCD. The testing module 100 includes one or more processing units 108 for handling the SCDs and PCR sample tubes. The processing unit 108 may include: (i) a barcode scanner configured to read a barcode on the SCD to be received by the sample input station; (ii) an oven or other heater configured to thermally lyse the saliva sample in the SCD received by the sample input station; (iii) an SCD processing mechanism configured to transfer a lysed microportion of the sample in a PCR sample tube attached to the SCD received by the sample input station; a sonicator configured to ultrasonically mix the lysed microportion of the sample, the water, and the lyophilized master mix in the PCR sample tube attached to the SCD. Suitable scanners, heaters and sonicators are known in the art.
The testing module 100 also may include one or more robotic manipulators configured to (i) separate the PCR sample tube from the SCD and discard the SCD into the biohazard waste bin 116 within the cabinet 114, (ii) seal the separated PCR sample tube, and (iii) transfer the sealed PCR sample tube to the PCR machine 106. The testing module 100 also may include a controller configured to operate the PCR machine 106.
The testing module 100 may include a consumables storage area in the main cabinet for the biohazard waste bin 116, for collection of used SCDs and PCR sample tubes. Disposal bay doors 118 may allow for access to the consumable storage area. The testing module 100 may also include an electrical cabinet 120 which may be accessed through a maintenance access door 122. The testing module 100 also includes a HEPA filter unit 110 and exhaust ports 112.
In operation, once the SCD is inserted in the testing module 100, the testing module will interact with the SCD, extract the biological specimen sample, lyse it, mix it with water and lyophilized master mix and present this mixture in the attached PCR sample tube, which in particular embodiments, is a standard 0.2 ml sample tube, as known in the art. The testing module 100 may separate the sample tube and/or sample container containing the sample from the SCD within the device; alternatively, the sample tube and/or sample container containing the sample may be separated from the SCD prior to being deposited in the testing module 100. The sample container of the SCD and the PCR sample tube will then be separated, with the sample tube then being sealed and processed in a PCR machine 106 while the SCD is discarded.
In one embodiment, SCD 300 is processed by a testing module after a patient uses the swab stick to collect a sample, places the swab stick in the sample container, and then deposits the swab stick and the sample container into the testing module. The testing module then may load a PCR sample tube, e.g., from a storage rack, and dispense a predetermined quantity of water (e.g. ˜15 uL) into the sample tube. The water may rehydrate the lyophilized master mix in the sample tube. The testing module then may attach the sample tube to the SCD as described above. The testing module then may depress the swab plunger to compress the absorbent swab, so that saliva is released into the bulk saliva collection chamber. The testing module may stop pressing plunger after translating a programmed distance. The testing module then may apply thermal energy to the sample container effective to heat the bulk saliva to 95° C. for several minutes and lyse the saliva sample. The testing module then may continue to depress the plunger which in return cause the metering piston (i.e., piercing plunger) to translate into the micro sample tube to eject 5 μl of the lysed saliva sample into the attached PCR sample tube. The testing module then applies ultrasonic energy to mix together the components in the PCR sample tube. Then, the testing module separates the SCD from the PCR sample tube and then seals the sample tube, e.g., with a film or foil material known in the art. The testing module then may place the PCR sample tube in a PCR machine and run a PCR test on the same in the PCR sample tube. The testing module may discard the used SCD into a waste receptacle. Once the PCR test is complete, then the testing module may also discard the sample tube into a waste receptacle.
In some embodiments, the SCD used in connection with the testing module may be provided in a two-part kit, which may be provided sterilized within flexible packaging prior to use.
The sample container 304 may have features that enable 1) bulk sample extraction from the swab stick 102; 2) lysis of the bulk sample; 3) and PCR sample tube attachment; and 4) metering of a microsample (˜5 μl) of the biological sample from the bulk sample, and transferring the microsample to the PCR sample tube. In embodiments, the PCR sample tube is pre-sealed prior to attachment to the sample container 104 and may contain a lyophilized master mix as known in the art. For example, a suitable lyophilized master mix for use in PCR detection of pathogens in biological samples may include PCR buffer, cofactor (e.g., MgCl2), dNTPs, probes (e.g., dye), and enzymes (e.g., polymerase and reverse transcriptase). In embodiments, primers, the sample, and water are added to the lyophilized master mix. In embodiments, if the testing module is configured to detect only a specific pathogen, the primers may be lyophilized and included in the master mix.
The sample container 304 as shown is releasably attached to a PCR sample tube 308, which contains a lyophilized master mix 310. The attachment may be by frictional engagement. The PCR sample tube attachment may be performed by the testing module after the SCD containing the collected biological specimen has been inserted into the testing module, or the PCR sample tube attachment may be performed by a user before the SCD containing the collected biological specimen is inserted into the testing module. The sample container also includes a projection 340 which is configured to pierce a seal on the top of the PCR sample tube 308 upon the attachment of the PCR sample tube 308 to the sample container 304. The projection 340 includes a through-channel that is in communication with the micro sample chamber 316.
After initial insertion of the saliva swap into the sample container, the saliva swab may be translated into the swab chamber 312 a first distance that will compress the saliva swab 301 and thereby release collected saliva into the bulk saliva collection chamber 314. After chemical or thermal lysing of the saliva in the bulk saliva collection chamber 314, further downward translation of the saliva swab into the swab chamber 312 a second distance will drive swab plunger 320, which extends from the holder 303, into contact with the metering piston 330 and drive at least part of the metering piston into the micro sample chamber 316, and displace the selected volume of the lysed saliva from the micro sample chamber 316 into the PCR sample tube 308. These translations of the first and second distances are performed in and by the testing module, for example by the processing unit 108 and/or one or more robotic manipulators.

As shown in
The sample is collected by the user using a SCD at sample collection step 501. At sample accession step 503, the sample is subjected to an accessioning process. In
The presently disclosed methods and systems, in conjunction with the SCDs and the local testing modules, advantageously may eliminate the need for shipping samples, and may yield a faster the PCR profile as compared with PCR profiles provided with conventional testing methods. As shown in
While the methods and system described herein are particularly useful in analyzing clinical specimens for the presence of infectious agents, such as those associated with various viruses, including the SARS-CoV-2 virus and influenza, the systems and methods described herein also can be used or readily adapted for use in the screening or diagnosis of a variety of other diseases and conditions in which PCR testing may be utilized. Non-limiting examples include measles, mumps, chlamydia, Bordetella pertussis Toxin, tuberculosis, H. pylori, zika, Mycoplasma pneumoniae, varicella zoster virus, VAV, borrelia, chagas, and sepsis. In other examples, the methods and devices described herein may be used in the screening of various other medical conditions, such as those related to bone and mineral health, thyroid, reproductive endocrinology, anaemia, autoimmunity, tumor markers, hypertension, adrenal function, growth, diabetes, viral hepatitis and retroviruses, treponema, Epstein-Barr Virus, TORCH (toxoplasmosis, rubella cytomegalovirus, herpes simplex, and HIV), as well as in stool diagnostics. PCR assays are known in the art for use in the diagnosis of a wide variety of diseases.
The biological sample is collected with a SCD at step 1204. For example, the SCD may include either a nasal or oral swab for collection of the sample, and the SCD may comprise water and/or reagents to be mixed with the sample. In embodiments, the SCD has a barcode or QR code or other means of identifying/tracking the SCD. Once the sample is collected, the SCD is placed in the testing module. At step 1206, the testing module scans the SCD so that a sample may be associated with a particular user or patient.
Once the sample has been identified, the sample may be inactivated at Step 1208. In some embodiments, the sample may be heated to render the sample non-infectious, for example to 95° C. for an effective period of time as known in the art. In some other embodiments, the sample may be irradiated, filtered, or exposed to solvents, detergents, or reagents with a low pH, as known in the art. The sample is also lysed, using techniques known in the art. Lysing may include exposing the sample to a detergent. In embodiments, the sample may be inactivated and lysed simultaneously. In some embodiments, the sample may be inactivated and lysed via heat; in such embodiments, the testing module comprises an oven or heaters known in the art.
In one embodiment, after the sample is lysed and inactivated, it may be added to a PCR tube at Step 1210. While the testing module can be used to test a single sample, it may also be used to test numerous samples at a time. In embodiments, the testing module comprises PCR plates with multiple wells. In embodiments, the testing module comprises more than one PCR tube and/or plate. The testing module comprises a liquid handler for filling the PCR tubes. In embodiments, consumable pipette tips are used to fill the tubes and are disposed of by the testing module. The sample is removed from the test tube before being added to a PCR tube. The liquid added to the PCR tube has a small volume, such as 5 uL. Once the sample has been removed from the test tube, the test tube is also disposed of by the testing module.
PCR sample tubes are sealed in step 1212. In some embodiments comprising a PCR plate, the testing module waits to test samples until a PCR plate is full. In some embodiments, the samples may be tested when the PCR plate is partially full. After the PCR plate is filled with the number of samples to be tested, it is sealed. Accordingly, the testing module may include a sealer for sealing the PCR plate, including consumables such as seal film, which are known in the art. In some embodiments comprising PCR sample tubes, the testing module may continuously run PCR tests, with sample tubes being continually added to and removed from the PCR machine. In those cases, the PCR tubes are sealed individually following receipt of a sample. Accordingly, the testing module may include a sealer for sealing the PCR sample tubes, including consumables such as seal film or closures (e.g., caps, plugs), which are known in the art.
At step 1214, PCR tests are performed on the sealed samples, and results of the PCR test are generated and reported as appropriate. Once the PCR testing is complete, the PCR tubes or plate are discarded, for example into a waste bin in the testing module.
The testing module itself may include one or more robotic manipulators (e.g., arms with actuators) reagents, storage for reagents and consumables, reagent plates, water, dispensers, pipette heads, PCR tubes and/or plates, waste receptacles, a tube/plate sealer, and one or more PCR machines. The testing module may scan the sample, prepare reagents and mix them with the sample, prepare and seal a PCR tube, and run it through a PCR machine.
