The TC, DC, Hb%, and ESR test is a comprehensive blood test that evaluates various parameters, including total count of white blood cells (TC), differential count of white blood cells (DC), hemoglobin concentration (Hb%), and erythrocyte sedimentation rate (ESR). It helps in assessing overall health, detecting infections, and diagnosing various conditions.

The TC, DC, Hb%, and ESR 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 ranges for TC, DC, Hb%, and ESR vary based on age, gender, and other factors. Values outside the reference ranges may indicate underlying health conditions, infections, or inflammation.

High TC: May indicate infection, inflammation, or leukemia. Low TC: May indicate bone marrow problems or autoimmune disorders.

A blood sample is required, typically drawn from a vein in the arm. The sample is then processed in the laboratory to analyze TC, DC, Hb%, and ESR.
