Indication and performance evaluation for verification and validation
Verification | Validation | |
---|---|---|
Indication | - Korean Food and Drug Administration (KFDA)–cleared/approved tests, the approved protocol and intended use | - Laboratory development testing - Modified use of KFDA-approved medical equipment for in vitro diagnosis - Additional sample types on an established platform |
Performance evaluation | - Accuracy testing (15 abnormal samples that represent abnormalities that the array is designed to detect) - Precision testing (establishment by running a minimum of two abnormal samples, ech run multiple times in separate experiments) - Reportable ranges |
- Accuracy testing (30 previously characterized abnormal samples that the array is designed to detect) - Precision testing (establishment by running a minimum of two abnormal samples, each run multiple times in separate experiments) - Reportable ranges - Sensitivity - Specificity - The allelic differentiation potential of SNP detecting platform - Determining percentage of cells with abnormality: mosaicism and clonality |
*Accuracy tests in cases where it is difficult to obtain 30 abnormal samples such as amniotic fluid and chorionic villous samples can be a good method of sample exchanges in a blind, split-sample comparison with a laboratory. Exchange of validated data sets (e.g., array files) between laboratories is recommended for additional experience in data analysis.
