Claims
- 1. A method of detecting the presence of a given chemical in biological fluids, comprising the steps of;
- depositing a test specimen in a first well on a base;
- contacting the contents of said first well with an absorbent strip of material;
- utilizing wicking action of the strip of material to transport said test specimen to a concentration chamber beneath a reagent retaining material where both the chamber and material are on the base;
- testing a portion of said strip within said concentration chamber with an agent which voltilizes a given chemical in said specimen;
- volatilizing said given chemical from said specimen when said specimen contacts said treated portion;
- concentrating said volatilized chemical;
- bringing said volatilized chemical into contact with a reagent; and
- observing said reagent to determine whether a color change has occurred, wherein the occurrence of the color change indicated the existence of said given chemical in the test specimen.
- 2. A method of detecting the presence of a given chemical in biological fluids, comprising the steps of:
- inserting a swab having an absorbent head and a handle into a source of biological fluid so that said head absorbs a test specimen of said biological fluid;
- inserting said head of said swab into a first well on a base where the first well contains a shelf and using said shelf to wring said test specimen from said head;
- contacting the contents of said first well with an absorbent strip of material;
- utilizing wicking action of the strip of material to transport said test specimen to a concentration chamber beneath a reagent retaining material where both the chamber and material are on the base;
- treating a portion of said strip within said concentration chamber with an agent which volatilizes a given chemical in said specimen;
- volatilizing said given chemical from said specimen when said specimen contacts said treated portion;
- bringing said volatilized chemical into contact with a reagent; and
- observing said reagent to determine whether a color change has occurred, wherein the occurrence of the color change indicated the existence of said given chemical in the test specimen.
