Platelet Count Blood Tests

Platelets are tiny blood cells that help your body form clots to stop bleeding. If you cut yourself, it’s the platelets that rush to the site of the injury and help seal the wound by forming a blood clot.

This test is crucial because having either too many or too few platelets can indicate a range of health issues. 

Low platelet counts (thrombocytopenia) can lead to excessive bleeding and bruising, showing that even minor injuries might cause serious bleeding. 

On the other hand, too many platelets (thrombocytosis) can lead to blood clots in your veins or arteries, which can cause strokes or heart attacks.

Doctors order platelet tests to monitor general health, diagnose diseases, or check the effectiveness of some treatments. It’s commonly performed if you have unexplained bruising or bleeding, are showing signs of an infection, or as part of routine health screenings.
