=====SOP of validation of new lot of Reagent strip===== **Objective** *To validate new lot of reagent strips before use **Requirement** *New lot *Validated lot in use *Testing sample **Procedure** *We validate every new batch of reagent strips by running the urine sample first with the old reagent strips of same parameters which is validated and in use and then re running it with new reagent strips and results are compared. *The results should be in concordance. **Lot validation records of reagents/reagent strips are filed in CP:C\Records\file\9\Internal quality control records-C(Lot validation Register)** =====SOP of Validation of new lot of chemical reagents===== **Objective** *To validate new lot of reagents before use **Requirement** *New lot *Validated lot in use *Testing sample **Procedure** *We validate every new batch of reagent by running the urine sample first with the old reagent of same parameters which is validated and in use and then re running it with new reagent and results are compared. *The results should be in concordance. **Lot validation records of reagents are filed in CP:C\Records\file\9\Internal quality control records-C(Lot validation Register)**
