Hematocrit Assessment

Meaning

Hematocrit assessment is a common clinical laboratory test that determines the proportion of blood volume occupied by red blood cells, expressed as a percentage. This measurement is a critical component of a complete blood count and serves as an indirect indicator of red blood cell mass and oxygen-carrying capacity. In endocrinology, monitoring hematocrit is essential, particularly during testosterone replacement therapy, as elevated levels can indicate polycythemia, a condition that increases the risk of thromboembolic events.
