What does the abbreviation Hct stand for in medical testing?

The abbreviation Hct stands for Hematocrit, which is a critical measurement in medical testing. Hematocrit refers to the proportion of blood volume that is occupied by red blood cells. It is expressed as a percentage, helping healthcare professionals evaluate a patient’s red blood cell count in relation to their total blood volume.

This measurement is essential in diagnosing conditions such as anemia, polycythemia, and various hydration statuses. A normal hematocrit level indicates a balanced production and destruction of red blood cells, whereas abnormal levels can signal underlying health issues. Understanding hematocrit values aids in managing a patient's blood health and overall medical condition, making it a key component in laboratory testing.
