The hemogram test, also known as HMG or Complete Hemogram Test, is a set of tests including complete blood count (CBC) and erythrocyte sedimentation rate (ESR) that help to assess the body’s overall health and aids in the detection of a variety of illnesses, including anaemia, infection, and leukaemia. It measures several components of blood, including red blood cells (RBCs) which carry oxygen, white blood cells (WBCs) which fight infection, haemoglobin (Hb) which is the oxygen-carrying protein in red blood cells, hematocrit which is the proportion of red blood cells to the total volume of blood, and platelets that help blood clot. ESR test is done to evaluate the degree of inflammation present in the body.
