Platelet Count
Platelets are cell fragments essential for blood clotting. Low platelets (thrombocytopenia) increase bleeding risk and can result from bone marrow disorders, autoimmune conditions, medications, or viral infections.
High platelets (thrombocytosis) can be reactive (infection, inflammation, iron deficiency) or primary (myeloproliferative disorder). Reactive thrombocytosis rarely causes clotting problems.
What It Measures
Number of platelets per microliter of blood.
Reference Ranges

| Normal | 150–400 K/µL |
| Borderline | 100–150 K/µL |
| Out of Range | < 100 K/µL or > 450 K/µL |
