B; The correct answer for this question is 1300 mg/dL. The laboratorian performed a 1:4 dilution by adding 0.25 mL (or 250 microliters) of patient sample to 750 microliters of diluent. This creates a total volume of 1000 microliters. So, the patient sample is 250 microliters of the 1000 microliter mixed sample, or a ratio of 1:4. Therefore, the result given by the chemistry analyzer must be multiplied by a dilution factor of 4. 325 mg/dL x 4 = 1300 mg/dL. - After experiencing extreme fatigue an...

ASCP MLS EXAM 2024 WITH 100% ACCURATE SOLUTIONS c antigen is most common in blacks and whites; anti-c would be most common reactive - correct answer Rh antibodies show enhanced reactivity with enzyme pretreated cells.
