While collecting a capillary sample for a H&H test, the MA notices that the blood flow is very slow from the capillary puncture. Once the hematocrit tube is filled appropriately, the MA begins to fill an EDTA microtube for the hemoglobin test. It takes a long time to obtain enough sample for the hemoglobin test, but finally it appears that there is enough blood in the tube. When testing the H&H a few minutes later, the MA finds that the hematocrit result is within the normal range while the hemoglobin result is quite low. What is a potential explanation for this discrepancy?
