What this test measures

This section shows the biological marker/agent measured by this diagnostic test. Each marker/agent opens its own page with related conditions. Detailed reference ranges are shown separately in the Reference ranges and concentrations section below, so they are not repeated here.

Reference ranges and concentrations

These ranges are pulled from the existing EH diagnostic-test reference range tables. They can vary by laboratory, method, age, sex, sample type and clinical situation.

Creatine Kinase (CK)	35 – 150	units/L	Adult ( > 16y)	Female	Blood Studies / Blood Enzymes
Creatine Kinase (CK)	40 – 170	units/L	Adult ( > 16y)	Male	Blood Studies / Blood Enzymes
Creatine Kinase (CK)	70 – 600	units/L	< 5 days	Both	Blood Studies / Blood Enzymes
Creatine Kinase1 (CK-BB) Isoenzyme	0 – 1	%	Adult ( > 16y)	Both	Blood Studies / Blood Enzymes
