【 摘 要 】

Sigma metrics is calculated in our lab and evaluated from December 2013 to November 2014. It is observed that Triglycerides,Lactate,Uric acid,AST, Urea,Creatine kinase(CK), Phosphate, Total Bilirubin are the best performers and the sigma value is more than 6.0 in both in normal and abnormal levels.Iron and Creatinine are best performers in normal level and Prolactin and Vitamin B12 are best performers in abnormal level. Amylase and LDH are the poor performers at level 1 ( normal), though they show sigma between 3 to 6 at level 2 which is clinically acceptable.
