What happens if PDW is high?

Platelet Distribution Width (PDW) is a measure of the variation in platelet size. A high PDW value suggests increased heterogeneity in platelet size. While a slightly elevated PDW may not be concerning, persistently high PDW levels may indicate underlying health conditions. High PDW values can be associated with various conditions, including platelet destruction disorders, bone marrow disorders, and certain types of cancers. It is important to consult a healthcare professional for a comprehensive evaluation if you have consistently elevated PDW levels.
