What may result in an inaccurate platelet count?

An inaccurate platelet count can occur due to a slow blood draw. This situation may lead to several issues: the prolonged time that the blood is in contact with the collection apparatus can result in clumping of platelets, which artificially lowers the count. Additionally, if the blood samples are not handled promptly or are allowed to sit for too long, the platelets may aggregate, leading to a misrepresentation of the actual platelet quantity in the circulating blood.

When a blood sample is collected slowly, it might also introduce artifacts related to the coagulation process, such as changes in platelet morphology, further complicating the accurate assessment of platelet numbers. These factors underscore why the method of blood collection is essential for obtaining reliable laboratory results.
