Platelet counts can be done manually using a hemocytometer or with an automated analyzer. … The ADVIA measures platelets by flow cytometry based on principles of light scattering. … The platelet cytogram on the left is a graphical representation of how the ADVIA counts platelets.

How do you calculate manual platelet count?

Is manual platelet count more accurate?

Manual platelet estimation using various methods in severe thrombocytopenia cases is more accurate compared to automated methods. However, the reproducibility of manual platelet counting has not been adequately studied.

How do you count platelets?

A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC).
