ABSTRACT:
Methods and reagents are disclosed for detecting a false result in an assay for determining a concentration of an analyte in a whole blood sample suspected of containing the analyte. The method comprises determining by means of the assay a concentration of the analyte utilizing a hemolyzed portion of the blood sample to obtain concentration value 1 and determining by means of the assay a concentration of the analyte utilizing a non-hemolyzed portion of the blood sample and multiplying the concentration times a hematocrit factor to obtain concentration value 2. A ratio of concentration value 1 divided by concentration value 2 is determined and is compared to a predetermined ratio of known reliability. If the ratio is less than the predetermined ratio, a false result is indicated.
