These disorders can be inherited (passed down in families) or acquired (developed after birth).

Symptoms

Platelets are one part of our clotting system, the system that helps us stop bleeding.

If your platelets don’t function properly, you are at an increased risk of bleeding.

Other types of platelet function disorders can havethrombocytopenia, or low platelet count.

The platelets should be reviewed under the microscope on a peripheral blood smear.

Several types of congenital platelet function disorders result in platelets that are larger than normal.

The remaining work-up begins similarly to other bleeding disorders.

Diagnosing platelet function disorders requires specialty testing.

Some platelet function disorders rarely need treatment unless you are injured or require surgery.
