Example
- Analyte
- Creatinine
- Program's target value
- 1.0
- Laboratory's response
- 1.15
Result: Acceptable: Creatinine response 1.15 is +0.15 mg/dL from the target 1 (15%); the limit is ±0.2 mg/dL.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Analyte
- Program's target value
- Laboratory's response
- Program's SD (white cell differential only)
- Decision level, for the limit as a percent (optional)
