Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Reference range

Male14 to 17.5 g/dL
Female12 to 16 g/dL

When it is low

Anemia: iron deficiency, chronic disease, blood loss, B12/folate deficiency

When it is high

Polycythemia, dehydration, high altitude, chronic hypoxia
