What this marker measures
Very low platelet counts can increase the risk of bruising or bleeding, while very high counts can in some cases increase clotting risk. Both extremes warrant medical evaluation.
High or low: what it can mean
High Platelets
A platelet count above normal (thrombocytosis) may occur after surgery, infection, or inflammation, or can sometimes reflect a bone marrow condition. Mildly elevated counts are often temporary.

Low Platelets
A platelet count below normal (thrombocytopenia) may mean the blood takes longer to clot. Causes range from certain medications and viral infections to conditions affecting platelet production.

Lifestyle considerations
- •Avoid NSAIDs (like ibuprofen) if platelets are low, unless directed by a doctor
