Full Blood Count
The Full Blood Count test evaluates the cells that circulate in your blood. Blood consists of three types of cells suspended in fluid called plasma: white blood cells, red blood cells, and platelets. They are produced and mature primarily in the bone marrow and, under normal circumstances, are released into the bloodstream as needed.
Significant abnormalities in one or more of the blood cell populations can indicate the presence of one or more conditions. Typically other tests are performed to help determine the cause of abnormal results. Often, this requires visual confirmation by examining a blood smear / peripheral blood film under a microscope to evaluate the appearance and physical characteristics of the blood cells, such as size, shape, and colour, noting any abnormalities that may be present. This information gives additional information to the cause of abnormal Full Blood Count results.
Erythrocyte sedimentation rate (ESR)
ESR is a test that indirectly measures the degree of inflammation present in the body. Inflammation is part of the body's immune response. It can be acute, developing rapidly after trauma, injury, or infection or can occur over an extended time (chronic) with conditions such as autoimmune diseases or cancer.
The ESR is not diagnostic; it is a non-specific test that may be elevated in a number of these different conditions. It provides general information about the presence or absence of an inflammatory condition.
