Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
3 mL refrigerated serum and 3 mL room temperature serum
Red-top tube or gel-barrier tube
Creatine kinase: refrigerate. Lactate dehydrogenase: maintain specimen at room temperature. Do not freeze or refrigerate. Creatine kinase: stable refrigerated for 48 hours or frozen for two weeks. Lactate dehydrogenase: stable at room temperature for seven days or refrigerated for no more than three days.
Creatine kinase: hemolysis. Lactate dehydrogenase: hemolysis; prolonged contact of serum with red cells; frozen specimen; specimen refrigerated more than three days after collection at time of testing.
Evaluation of possible myocardial damage or other cardiac diseases. See individual test descriptions for CK Isoenzymes and LD Isoenzymes.
Total: kinetic; Isoenzymes: agarose gel electrophoresis with densitometry
