The table below lists several groups of laboratory tests (along with a brief description of each group) for which content and articles are available. Clicking on the group name will lead you to the names of individual tests belonging to the group for which articles are available.

Test NameDescription
Clotting TestsBlood that flows within the blood vessels is in the fluid form. It clots when there is a break in the blood vessels to stop the flow of blood. Clotting tests detect abnormalities in blood clotting. Common clotting tests are the prothrombin test, the thrombin test and the activated partial thromboplastin test (aPTT). The D-dimer test is done in COVID-19 patients to identify patients at an increased risk of clot formation.
HemogramBlood contains three types of cells, the red blood cells or erythrocytes, the white blood cells or leucocytes, and the platelets. The hemogram is used to study the blood cells and hemoglobin, a pigment present in the red blood cells.
Hormonal assaysHormones are chemicals released into the blood that act of different parts of the body. Hormonal assays are required to identify hormonal deficiencies or excesses, so that appropriate corrective measures can be taken.
Iron studies, vitamin B12 and folate levelsIron, vitamin B12 and folate are required by the red blood cells. The estimation of these levels can indicate the possible cause of anemia.
Peripheral smearThe peripheral blood smear is used to study the details of the blood cells such as number, shape and contents. It can also identify the presence of blood parasites.
Platelet testsPlatelets are blood cells the help to control blood loss following an injury. The platelet tests evaluate the platelets for their number, structure as well as function.
Tests to assess liver functionBlood tests can assess the liver function. These tests include those that measure the enzymes produced by the liver, proteins present in the blood and bilirubin, a pigment that undergoes processing in the liver.
Tests to check for inflammationInflammation is a protective response of the body to an infection. Excessive inflammation, however, can damage organs and joints. Tests such as erythrocyte sedimentation rate, C-reactive protein estimation and procalcitonin can be used to estimate the inflammatory status of the body.
