What is the abbreviation for red blood cell count?

The abbreviation for red blood cell count is RBC, which stands for "Red Blood Cells." This term refers specifically to the number of red blood cells present in a microliter of blood, a crucial measurement in assessing an individual's overall health and diagnosing various medical conditions. A normal RBC count can indicate proper body function, whereas deviations from the norm may suggest issues such as anemia, dehydration, or other hematological disorders.

The other options represent different components or measurements in blood analysis: WBC stands for white blood cell count, which measures the number of white blood cells and is essential for evaluating immune function; PLT denotes platelet count, which is vital for understanding clotting factors in the blood; and HCT refers to hematocrit, which measures the percentage of blood volume made up by red blood cells. Each of these abbreviations serves a distinct purpose in medical diagnostics, reinforcing the specificity inherent in medical terminology.
