title: Preservation of whole blood samples for creatine kinase isoenzyme MB estimations in the routine laboratory.
abstract: Activity of creatine kinase isoenzyme MB was maintained for 5 days at 4 degrees C in 5 ml whole blood collected in specimen bottles containing 9.5 mg EGTA and 2 microliters beta-mercaptoethanol for glutathione-activated CK-MB assays and 7.5 mg EDTA for N-acetyl-L-cysteine-activated CK-MB assays.
