PCR Efficiency 90-110 Percent Standard Curve Slope Checker
Compute PCR standard-curve efficiency E=(10^(−1/slope)−1)*100 and screen the educational 90–110 percent window; no assay validity guarantee.
Description
Compute PCR standard-curve efficiency E=(10^(−1/slope)−1)*100 and screen the educational 90–110 percent window; no assay validity guarantee.
A PCR standard-curve slope relates cycle thresholds to log10 template quantity. Converting the slope to an efficiency estimate assumes that this is the calibration convention used.
When to use this tool
Compute PCR standard-curve efficiency E=(10^(−1/slope)−1)*100 and screen the educational 90–110 percent window; no assay validity guarantee.
- Prepare the supplied standardCurveSlope fields for this operation.
- Compare the complete example with the representation used by your own input before carrying the result into another step.
How to use the tool and how it works
- Enter standardCurveSlope. Use the exact text syntax, units and index conventions explained below.
- Run the tool. If input validation fails, correct the supplied fields before interpreting any result.
- Read result.efficiencyPercent, result.in90110Window. Interpret false, null and empty lists using the distinctions below; they can be valid outputs.
Require standardCurveSlope to be negative. Calculate efficiencyPercent=100*(10^(-1/standardCurveSlope)-1), then set in90110Window when that percentage lies inclusively from 90 through 110.1
| Input field | Meaning and representation | Accepted input |
|---|---|---|
| standardCurveSlope | standard curve slope. | Finite number |
| Output field | Interpretation |
|---|---|
| result | Object containing the named outputs below. |
| result.efficiencyPercent | The efficiency percent value under the stated formula or text convention. |
| result.in90110Window | Flag for in90110 window under the exact condition described above. |

}Limitations and assumptions
- The tool does not fit a standard curve or verify its axes, linearity or measurements. The fixed window is the implementation's screen rather than universal assay acceptance; nonfinite results are rejected.
- Every declared top-level field is required and unexpected fields are rejected. Numeric inputs must be finite; ordinary text fields are bounded to 8,192 UTF-16 code units, with tighter operation-specific limits where stated.
- Ordinary string lists have at most 128 entries of at most 128 code units each; numeric lists and matrices have separate bounded size checks. Nonfinite results and excessively large serialized outputs are rejected.
- Indexes are zero-based and spans have an exclusive end unless explicitly stated otherwise. A valid false, null or empty-list result is distinct from malformed input.
Alternative or Complementary methods
Keep physical-particle counts, infectious assay units and observed sample proportions distinct. Use the original calibration, product instructions or validated assay method for the specific context; simple conversions and reference notes do not establish infectivity or clinical interpretation.
