Confirmatory tests for hemolytic anemia involve a variety of laboratory tests and blood tests. These tests are used to identify the underlying cause of the anemia, which helps to determine the best course of treatment. The most common confirmatory tests for hemolytic anemia are:
Complete Blood Count (CBC)
The CBC is the most commonly ordered test to diagnose hemolytic anemia. This test measures the levels of red blood cells, white blood cells, and platelets in your blood. An abnormally low red blood cell count may indicate anemia.
Peripheral Blood Smear
A peripheral blood smear is a microscopic examination of the red blood cells. This test can help identify the type of anemia present and determine the cause of the anemia.
Reticulocyte Count
A reticulocyte count is a test that measures the number of immature red blood cells in the blood. An abnormally low reticulocyte count may indicate hemolytic anemia.
Haptoglobin Test
The haptoglobin test measures the amount of haptoglobin, a protein, in the blood. High levels of haptoglobin may indicate hemolytic anemia.
Direct Antiglobulin Test (DAT)
The DAT is a test that detects antibodies on the surface of red blood cells. This test can help to identify the cause of the anemia and identify whether it is an autoimmune disorder or if it is caused by a transfusion reaction.
Bilirubin Test
The bilirubin test measures the amount of bilirubin, a byproduct of red blood cell destruction, in the blood. High levels of bilirubin may indicate hemolytic anemia.
