What it measures

Cell fragments responsible for blood clotting. Critical for bleeding-risk assessment.

What a high value can mean

Inflammation, iron deficiency, post-splenectomy, essential thrombocythemia.

What a low value can mean

ITP, sepsis, marrow disease, certain medications, viral infections (e.g., dengue).

Conditions it helps assess

Bleeding risk
Clotting disorders
Bone marrow function

Reading these numbers in context

Reference ranges describe the central 95 % of a healthy reference population — 5 % of perfectly healthy people fall outside any given range by definition. A single mildly abnormal value is rarely meaningful on its own. blood-test.life always interprets values together with related biomarkers before flagging.

Related biomarkers in Complete Blood Count (CBC)

Hemoglobin HGB Oxygen-carrying protein in red blood cells. Low hemoglobin is the defining marker of anemia. Hematocrit HCT Percentage of blood volume occupied by red blood cells. Moves in parallel with hemoglobin. White Blood Cell Count WBC Total count of infection-fighting white cells. Subtypes (neutrophils, lymphocytes) carry far more diagnostic weight. Mean Corpuscular Volume MCV Average size of red blood cells. Categorizes anemia as microcytic, normocytic, or macrocytic.
