Curve fit EIA

Competitive enzyme immunoassay (EIA) for the quantitative measurement of salivary cotinine (ng/mL).

Calculations are made by subtracting the mean of the NSB measurements from the provided optical densities. The B/B0 is calculated from the corrected values using the mean of the B0 group. Concentrations are calculated using a Four Parameter Logistic Fit (4PL) and dilution factors are applied.
