Which test must be performed on whole blood-?

The following tests must be performed on whole blood:

- Complete blood count (CBC): A CBC measures the number of red blood cells, white blood cells, and platelets in a sample of blood. It can also provide information about the size and shape of red blood cells, as well as the amount of hemoglobin in the blood.

- Coagulation studies: Coagulation studies measure the ability of blood to clot. These tests are used to diagnose bleeding disorders and monitor the effectiveness of anticoagulant therapy.

- Blood culture: A blood culture is a test that checks for the presence of bacteria or fungi in the blood. Blood cultures are typically performed when a person has a fever or other signs of infection.

- Arterial blood gas (ABG): An ABG test measures the levels of oxygen and carbon dioxide in arterial blood. ABG tests are used to assess the function of the lungs and kidneys.

- Venous blood gas (VBG): A VBG test measures the levels of oxygen and carbon dioxide in venous blood. VBG tests are used to assess the function of the lungs and kidneys when an arterial puncture is not possible.

- Type and screen: A type and screen is a test that determines a person's blood type and checks for the presence of antibodies that could react with transfused blood.

- Hemoglobin A1c test:A hemoglobin A1c test measures the average blood sugar level over the past 3 months. This test is used to diagnose and monitor diabetes.
