Tests
The determination of the ratio of aspartate aminotransferase compared to creatine kinase present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
This test measures the amount of creatine kinase (CK) in a sample of your blood. CK is also called creatine phosphokinase (CPK).
Indicators
An enzyme complex that can reversibly convert ATP and creatine to phosphocreatine and ADP. Cytosolic creatine kinases are comprised of homodimers or heterodimers of creatine kinase B-type protein and creatine kinase M-type protein. Mitochondrial creatine kinases are octomers comprised of either four homodimers of creatine kinase U-type, mitochondrial protein or four creatine kinase S-type, mitochondrial protein homodimers.
