There are many tests on the hematology test list. Some test is performed on a routine base like Complet Blood Count, Hemoglobin estimation while some test performed on special circumstance bone marrow examination(Leukemia condition).
What is the Hematology most common tests (CBC) list?
Hematology is a broad field of medical science. The hematology test list contains many clinical lab tests. A routine test list is given below.
- Complete Blood Count (CBC)

Here are the Hematology test list and their explanation.
- Hemoglobin estimation test. This used to check the oxygenation capacity of the body on the base of Hemoglobin (Hb estimation by Sahli’s method).
- Complete Blood Count: This test is used to check the body’s blood-producing ability. It includes MCV, Hematocrit, granulocyte%, Eosinophil, Basophil, MCH, MCHC.
- Prothrombin Test PT: This test used measures how long it takes blood to clot.
- A prothrombin time test (APTT): This test is used to check for bleeding problems.
