For education. Check every result.

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

Range0 to 5 ng/mL

When it is low

Normal

When it is high

MI (rises 4-6h, peaks 12-24h), cardiac surgery, myocarditis
