Blood Count
Platelet Count — what it measures
For understanding, not diagnosis. Reference ranges differ between laboratories; the ranges on your own report, and your doctor’s reading of them, always come first.
What it measures
Platelets are the small blood particles that form clots to stop bleeding. Their count is part of the complete blood count and is checked before surgery and when bruising or bleeding questions arise.
What can skew it
Recent infection or inflammation can push platelets up, and some samples clot or clump in the tube, producing a falsely low count that labs may flag for re-check.
Reference ranges
Reference ranges vary by laboratory, so interpret your count only against your own report and with your clinician.
