Validation checklist — saved on this device only
Set the status of each validation parameter. The counts above update from this checklist, which is saved on this device only (gifsq_tool_291). Use Clear to wipe the saved checklist.
| Validation parameter | Status |
|---|---|
| Selectivity | |
| Linearity | |
| Detection limit | |
| Quantification limit | |
| Precision (repeatability) | |
| Trueness / recovery | |
| Working range | |
| Robustness | |
| Measurement uncertainty | |
| Ruggedness |

Remaining
Equation: Complete (%) = completed ÷ total × 100. Pass rate (%) = passed ÷ completed × 100. Remaining = total − completed.
Method: Validation tracking per ISO/IEC 17025 clause 7.2 and Eurachem method-validation guidance: a validation is complete only when every required parameter (selectivity, linearity, detection and quantification limits, precision, trueness, range, robustness, uncertainty) has been finished and passed.
Assumptions: the counts come from the checklist below; a parameter counts as completed only when it has passed or failed, not while it is in progress.
Limitations: the tracker records status, not evidence — the underlying data and reports still need review; a 100% pass rate on a partial parameter set is not a complete validation.
Rounding: percentages to 2 decimal places; remaining is a whole number; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.

Worked example: 12 validation parameters, 9 completed, 8 passed: complete = 75.00%, pass rate = 88.89%, remaining = 3.
Enter values above to see results.
A validation is done when every parameter is completed — a high pass rate on a half-finished study is not a pass. Tool 291 of 500 — GIFSQ
