Clinical Notes

Platelet count (Plt) helps assess bleeding, thrombotic, and neoplastic processes. It assists in the evaluation of bone marrow function, as well as the study of some diseases involving autoimmune mechanisms. Platelets are measured in parts per cubic mm (mm3) and often expressed as 1000/μL or x 109/L.
