PDW
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.

What is PDW?
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.
What might a high or low PDW mean?
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.
What is the typical reference range for PDW?
The general-population reference range shown here is 9 – 17 fL. Reference ranges describe the general population and are not a personal target — discuss your results with your physician.
