PDW

Complete Blood CountBlood HealthBlood

Platelet distribution width, or PDW, measures how varied the widths of the platelets are. A platelet count, PDW and an MPV blood test are parts of a complete blood count that provide helpful information about platelets.

Why it matters: Together, these platelet tests can help a provider investigate multiple conditions, including a low platelet count, called thrombocytopenia, and a high platelet count, called thrombocytosis.
