  • Compositions and method for correcting temperature dependence of hemoglobin assays
    Patent number: 4448888
    Abstract: Artificially constituted storage-stable hemoglobin compositions for use in the temperature correction of a cation exchange column chromatographic assay for hemoglobin A.sub.1 or A.sub.1c in a sample of human blood. The relative amounts of hemoglobin components in the composition conform approximately to the following formula:______________________________________ y = mx + b where y = weight percent A.sub.1c with respect to A.sub.1 x = weight percent A.sub.1 with respect to total hemoglobin m = -1.7 and b = 85 when x < 10, and m = -1.2 and b = 80 when x > 10. ______________________________________The compositions when analyzed in a cation exchange assay produce a result which varies with temperature in substantially the same manner as that from a true sample of human blood.
