  1. Mr.Shashikant Mahadik Scientific Officer Hematopathology,TMH,Mumbai

  2. -Plotting of Levey-Jennings chart- Application of Westgard Rules- Calculation of coefficient of variance

  3. Control Material Commercial / In-house (for coagulation) Tri-levels 1st or 3rd party controlsMonitoring of control L-J charts, Westgard rules and %CV

  4. Accuracy : Closeness of a result to the true valuePrecision : refers to the reproducibility of a resultYou cannot have accuracy without precision, but can have precision without accuracy

  5. Calibration : is done to standardize the instrument for accuracyCalibrator : is a certified reference material used calibrate a measurement on analyzer
