What is the reason for the high platelet distribution width

summary

As you should know, platelets are a kind of adhesive in human blood. Many diseases are related to them, such as hemophilia. Today, let's look at the reasons for the high distribution width of platelets.

What is the reason for the high platelet distribution width

First: Generally speaking, the average distribution width of platelets, abbreviated as PDW. It is a parameter reflecting the variation of platelet volume. PDW is too large, which proves that the shape and size of platelets in the body are not very uniform. He usually diagnosed some diseases together with other indicators.

Second: another is that the normal platelets in the blood are disc-shaped, smooth surface, when contact with the foreign body surface or in non physiological conditions, it becomes spherical, expansion, hemostasis. On the one hand, the width of platelet distribution is relatively high, and there are physiological fluctuations, such as after exercise and meals.

Third: finally, thrombocytosis: when it is more than 400x109 / L, it is thrombocytosis. Primary thrombocytosis is common in myeloproliferative diseases, such as chronic myeloid leukemia, polycythemia vera, primary thrombocytosis, etc.; reactive thrombocytosis is common in patients with acute and chronic inflammation, iron deficiency anemia and cancer.

matters needing attention

Platelet distribution width is on the high side. Generally, there is no disease. However, we should not take it lightly. It is suggested to find out the cause of the disease so as not to delay the disease.
