Claims
- 1. A method for determining hemoglobin in a blood sample which comprises the step of:
- (a) combining the blood sample with a reagent composition including an ionic surfactant at a concentration of from about 2 to 4 percent weight to volume, which reagent composition has a pH of from about 11.3 to about 13.7 and is free of ionic cyanide to form a reaction mixture;
- (b) measuring the absorbence of said reaction mixture as an indication of hemoglobin in said blood sample.
- 2. A method of claim 1, wherein (b) comprises measuring the absorbence within 30 seconds of having formed said reaction mixture.
- 3. The method of claim 1, wherein said ionic surfactant is a zwitterionic surfactant and (b) comprises measuring the absorbence of said reaction mixture at about 570 nm.
- 4. The method of claim 1, wherein said ionic surfactant is a cationic surfactant and (b) comprises measuring said absorbence at about 594 nm.
- 5. The method of claim 1, wherein said ionic surfactant is an anionic surfactant and (b) comprises measuring said absorbence at about 603 nm.
