Hairy cell leukemia laboratory tests
Introduction
Overview
Overview
Laboratory findings consistent with the diagnosis of hairy cell leukemia include abnormal complete blood count, immunohistochemistry, and flow cytometry. The presence of hairy cells with thread-like cytoplasmic extensions on blood smear is a key diagnostic feature among patients with hairy cell leukemia.
Laboratory Findings
Laboratory Findings
Laboratory findings consistent with the diagnosis of hairy cell leukemia include:[1][2][3][4][5]
Complete Blood Count
- Anemia – Decreased hemoglobin concentration[6]
- Thrombocytopenia – Decreased platelets count
- Decreased WBC count
- Neutropenia
- Elevated BUN (Blood urea nitrogen)
- Abnormal liver function tests
- Hypergammaglobulinemia may be positive in small percentage of patients with hairy cell leukemia
- Leukocytosis
- Monocytopenia
Blood Smear
- Hairy cells with thread-like cytoplasmic extensions[7][8]
- Positive TRAP stain[9]
Immunohistochemistry and Flow Cytometry
