Abstract
The quality control sera commonly available in market does not provide the value of CKMB. The CKMB kit of Randox laboratories contains two lyophilized control sera. But the stability of the control serum after reconstitution with 2ml of distilled water is 5 days at 2–8 degree Celsius, 8hrs at 25 degree Celsius and 4 weeks at-20 degree Celsius when frozen once. Hence stability after reconstitution is not sufficient to fulfill the daily need of a laboratory. In quest of a good internal quality assessment (IQA) sample trial run has been performed at 37 degree Celsius using external quality assessment (EQA) samples obtained from Randox international quality assessment sample (RIQAS). The trial run was found to be successful.
