2.0 mg hemoglobin/100 ml water.
Accuracy and Precision: Sample (n=20) containing
2.0 mg hemoglobin/100 ml water were repetitively checked and found to be
positive each time (100%). A repetitive performance of the test (n=20) on
sample devoid of RBC or hemoglobin, gave negative results each time (100%).
EZ DETECT™--GENERAL
PRINCIPLE
Peroxide (On test pad) + Hemoglobin -- Water + Oxygen
Oxygen + Unoxidized TMB on test pad -- Oxidized TMB
