More generally, the formula for the 95% confidence interval on the mean is: Lower limit = M - (tCL)(sM) Upper limit = M + (tCL)(sM) where M is the sample mean, tCL is the t for the confidence level desired (0.95 in the above example), and sM is the estimated standard error of the mean.
Limit of Detection (LOD) or detection limit, is the lowest concentration level that can be. determined to be statistically different from a blank (99% confidence). The LOD is typically. determined to be in the region where the signal to noise ratio is greater than 5.
