What is CD42a (Megakaryocytic Cell Marker)?

What does CD42a (Megakaryocytic Cell Marker) measure?
Measuring CD42a shows whether cells in blood or bone marrow are from the platelet line. Doctors use it when they need to identify platelet-related cells.

What symptoms suggest CD42a (Megakaryocytic Cell Marker) may be needed?
A doctor may recommend CD42a (Megakaryocytic Cell Marker) when a patient reports any symptom your doctor has identified as requiring objective laboratory investigation , including unexplained fatigue, unexplained weight change, persistent pain, fever, or abnormal bleeding.
