How is Hairy Cell Leukemia Diagnosed?

Blood Tests:

• Complete Blood Count (CBC): This test measures the amount of different types of blood cells in a sample of your blood. People with Hairy Cell Leukemia (HCL) often have low levels of red blood cells, white blood cells, and platelets.
• Blood Smear: In this test, a sample of your blood is examined under a microscope to check for hairy cells. The cells are called 'hairy' because they have fine, hair-like projections coming off their surface.
• Flow Cytometry: This test is used to identify hairy cells based on the types of proteins on their surface. It can help confirm a diagnosis of HCL.

Bone Marrow Tests:

• Bone Marrow Aspiration and Biopsy: These tests involve taking a small amount of bone marrow from your hipbone and examining it under a microscope. The presence of hairy cells in the bone marrow can confirm a diagnosis of HLC.
• Cytogenetic Analysis: This test looks at the chromosomes of cells from samples of blood, bone marrow, or lymph nodes. It can help identify genetic changes that might cause HLC.

Imaging Tests:

• Computed Tomography (CT) Scan: This test can help determine the size of your spleen and lymph nodes, which can be enlarged in people with HLC.
• Magnetic Resonance Imaging (MRI): This test can provide detailed images of your internal organs and can help assess the extent of the disease.

A Summary of Diagnosing Hairy Cell Leukemia

Diagnosing HCL involves a combination of blood tests, bone marrow tests, and imaging tests. The process begins with a blood test to check for low levels of blood cells and the presence of hairy cells. If these tests suggest HCL, a bone marrow test is done to confirm the diagnosis. Imaging tests can help determine the extent of the disease. The results of these tests help doctors determine the most appropriate treatment options.
