Overview
The purpose of the CD61 test is to identify and quantify platelets and megakaryocytes in a sample, aiding in the diagnosis of disorders such as immune thrombocytopenia (ITP), thrombocytosis, and myeloproliferative neoplasms. It helps in assessing platelet function and megakaryocyte proliferation, providing critical information for clinical management.

- Hemolyzed or clotted samples
- Incorrect container or anticoagulant
- Insufficient sample volume
- Missing clinical details on request form
Understanding Your Results
Indicates normal platelet and megakaryocyte counts, consistent with no active disorder
Level: Normal CD61 expression
May suggest thrombocytosis or myeloproliferative neoplasms
Level: Increased CD61+ platelets
Could indicate immune thrombocytopenia (ITP) or other platelet consumption disorders
Level: Decreased CD61+ platelets
May reflect bone marrow disorders such as myelofibrosis or leukemia
Level: Abnormal megakaryocyte CD61
If you experience symptoms like easy bruising, excessive bleeding, or fatigue, or if test results are abnormal, consult a hematologist or oncologist for further evaluation and management.
Limitations
- ⚠Cannot distinguish between all types of myeloproliferative neoplasms
- ⚠Requires specialized flow cytometry equipment and expertise
- ⚠Results should be correlated with clinical history and other tests
Risks & Considerations
- ●Minimal risks for blood draw: bruising, slight pain at puncture site
- ●For bone marrow aspiration: risk of infection, bleeding, or discomfort, which are rare with proper technique
Interfering Factors
- ●Hemolyzed or lipemic samples
- ●Improper anticoagulant use
- ●Sample storage beyond stability period
- ●Contamination during collection
