Use: 

The HCT is the comparison of the cellular portion of the blood to the serum (fluid) portion. This comparison is reported as a percentage. A low number of red blood cells causes a low HCT. Men tend to have higher hematocrits than women. The hematocrit is often used along with a hemoglobin to evaluate anemias, blood loss, and state of hydration or suspect polycythemic condition and response to treatment. 

 

Causes for Rejection:  Hemolysis; clotted specimen; tube not filled with minimum volume; improper labeling; specimen received in any anticoagulant other than EDTA; specimen received with plasma removed; specimen diluted or contaminated with IV fluid; specimen received in whole blood transport tube; specimen more than 48 hours old.
