PDW stands for Platelet Distribution Width and it's a measure of the variation in platelet size in a person's blood. A PDW blood test is usually done as part of a complete blood count (CBC). The test involves taking a blood sample from a vein in the arm, which is then analyzed in a lab.

Platelet distribution width (PDW) test is a measure of the variation in platelet size, and can be used as an indicator of platelet activation and the presence of platelet disorders. It is often reported as part of a complete blood count (CBC) test, which also measures the number and size of red blood cells, white blood cells and platelets.

2024年12月13日 · Learn about the Platelet Distribution Width (PDW) test, including its symptoms, causes, and management. Understand how PDW can indicate underlying health issues and what steps you can take for better health.

PDW reflects how uniform the platelets are in size. A normal PDW indicates platelets that are mostly the same size, while a high PDW means that platelet size varies greatly, a clue that there is platelet activation and has been associated with vascular diseases and certain cancers.

The PDW blood test is generally used as a screening tool to see if a patient is experiencing good health. It is typically ordered as part of a routine health screening. If bone marrow disorders are suspected, however, it may also be ordered.

What happens if PDW count is low? A low PDW (Platelet Distribution Width) count indicates decreased variability in platelet size. While a slightly decreased PDW may not have significant clinical implications, persistently low PDW levels could suggest certain health conditions.

Platelet distribution width (PDW) reflects variability in platelet size, and is considered a marker of platelet function and activation . Increased PDW values have been reported in patients with diabetes mellitus , cancer [6,7], and cardio-cerebrovascular and respiratory disorders [8–12].

Background: Platelet indices are potentially useful markers for the early diagnosis of thromboembolic diseases. An increase in both mean platelet volume (MPV) and platelet distribution width (PDW) due to platelet activation, resulting from platelet swelling and pseudopodia formation was hypothesized.

2024年12月26日 · Read about Platelet Distribution Width (PDW), its role in diagnosing health conditions, how the PDW blood test is performed, and what high or low PDW levels mean for your health.

PDW measures the variation in platelet size, crucial for diagnosing conditions like vascular diseases and certain cancers. Monitoring PDW levels can help detect and manage these conditions early.
