Essential Blood Tests for Overall Health Assessment

It is a simple blood test to look for the levels of Hb (haemoglobin), TC (total count), DC (differential count), platelets in blood and ESR (erythrocyte sedimentation rate). This test shows general health of the person.

Hb test measures amount of haemoglobin in blood. The Hb is vital protein present in red blood cells that carry oxygen from the lungs to different tissues of the body and carbon dioxide back from tissues to the lungs. A low level of Hb indicates a condition called anaemia which can be due to different causes.

TC blood test measures the total number of white blood cells also called leucocytes in blood. Their function is to defend the body against various infections.

DC blood test measures the percentage of various components of white blood cells in blood. These components are neutrophils, eosinophils, basophils, lymphocytes and monocytes.

Erythrocyte Sedimentation Rate tests measures how fast erythrocytes (red blood cells) settle down in a test tube containing blood sample. If ESR is high it may indicate inflammation which can be due to infection, injury, chronic disease or some immune disorder.

Platelet count measures platelets in blood. Platelets are also called thrombocytes.The function of platelets is stop bleeding by forming blood clot.
