Part of a CBC; a rising value in dengue can signal plasma leakage.
No fasting needed. Typical adult range: men: 40 to 50 % (source: Mayo); women: 35 to 45 % (source: Mayo). Ranges vary by lab, age and sex; use the range on your report. High values may mean: Dehydration, plasma leakage in dengue, high altitude. Low values may mean: Anaemia, blood loss. General information, not a diagnosis. Results must be interpreted by a qualified health worker.
⚠️ Reference ranges vary by lab, age and sex — always use the range printed on your own report.
Consult a doctor to interpret results — a single test does not make a diagnosis.
