The TC-WBC test measures the total cholesterol content within white blood cells. It provides insights into cholesterol metabolism at the cellular level, potentially aiding in the assessment of lipid disorders and cardiovascular risk.

The TC-WBC (Total Cholesterol - White Blood Cell) test is a standard blood test with minimal risk. The primary risk is related to the blood draw, which may cause minor bruising, bleeding, or infection at the puncture site.

The reference range for TC-WBC varies but is typically less than 50 μg/10^9 WBCs. Values above the reference range may indicate altered cholesterol metabolism within white blood cells.

Elevated TC-WBC levels: May suggest disturbances in cholesterol metabolism within white blood cells, potentially associated with lipid disorders or increased cardiovascular risk. Normal TC-WBC levels: Suggests cholesterol metabolism within white blood cells is within expected ranges.

A blood sample is required, typically drawn from a vein in the arm. The sample is then processed in the laboratory to measure the cholesterol content within white blood cells.
