Understanding Lab Tests for Aplastic Anemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Aplastic anemia is a rare but serious condition where the bone marrow fails to produce sufficient new blood cells, including red blood cells, white blood cells, and platelets. This potentially life-threatening disorder requires prompt diagnosis through comprehensive blood testing.
Recommended Test
White Blood Cell Count (WBC)
This test measures the number of white blood cells in your blood, which are essential for fighting infections. In aplastic anemia, the bone marrow's reduced ability to produce new blood cells typically results in a significantly low WBC count, making this test crucial for diagnosis and monitoring of the condition.

How Blood Tests Diagnose Aplastic Anemia
Blood tests are the primary diagnostic tool for aplastic anemia. The condition is characterized by low counts of all blood cell types (pancytopenia), which can be detected through routine blood work. Early detection is crucial as the condition can lead to severe complications including increased infection risk, bleeding problems, and fatigue.
Understanding Your Results
A low white blood cell count can indicate that your bone marrow is not functioning properly. When combined with other blood cell counts and clinical symptoms, this test helps healthcare providers confirm a diagnosis of aplastic anemia and determine the severity of the condition.
