- Linear standard concentrations
- 0,1,2,4
- Standard response readings
- 0.1,0.6,1.1,2.1
- Unknown sample responses
- 0.85,1.6
- Linear fit [slope,intercept,R²]
- [0.5,0.1,1]
- Sample concentrations
- [1.5,3]
Try another scenario
- Linear standard concentrations
- [0, 1, 2, 4]
- Standard response readings
- [0.1, 0.6, 1.1, 2.1]
- Unknown sample responses
- [0.6, 1.1]
- Linear fit [slope,intercept,R²]
- [0.5,0.1,1]
- Sample concentrations
- [1,2]
Calculation method
Calculation method
Linear fit [slope,intercept,R²]
OLS response versus concentration.
Sample concentrations
(response−intercept)/slope; reject extrapolation outside measured concentration span.

Assumptions & limits
Assumptions & limits
- Supported standard curve: ordinary least-squares linear response. Nonlinear, weighted and logistic assay models require another method; extrapolation is rejected. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Linear standard concentrations: minimum 0, maximum 1000000000000.0. Standard response readings: minimum None, maximum 1000000000000.0. Unknown sample responses: minimum None, maximum 1000000000000.0.
