Blood smear: A blood smear is a microscopic examination of a blood sample, used to identify abnormalities in the appearance and function of blood cells.

Coagulation tests: These tests evaluate the function of the clotting system, including tests of clotting factors, platelet function, and fibrinolysis.

Bone marrow biopsy: This test involves taking a small sample of bone marrow (the spongy tissue inside bones that produces blood cells) and examining it under a microscope, to diagnose blood disorders and evaluate the health of blood-forming cells.

Serum protein electrophoresis: This test measures the amount and types of proteins in the blood, including antibodies and immunoglobulins.
