Enzyme immunoassay for the quantitative in vitro diagnostic measurement of DHEA-S in serum and plasma. This method calculates the average absorbance values for each sample. A standard curve is plotted from the mean absorbance against the specified concentration values. A Four Parameter Logistic fit is performed through the data points and used to calculate concentrations for all samples. Samples with concentration values higher than that of the highest standard are highlighted in yellow and should be diluted further.

The DRG Corticosterone ELISA (EIA-4164) is an enzyme immunoassay for the measurement of Corticosterone in serum and plasma. This analysis calculates concentrations in nmol/L in using a Four Parameter Logistic fit in accordance with the kit instructions. The standard data points (concentration vs. measurement) are plotted on semi-log axes and a 4PL is made through the average of the replicated standards. The concentrations of the samples are determined from the fit with any specified dilution factors applied. The %CV, Standard Deviation and Standard Error are calculated for each replicated sample. Samples outside the range of the standards or the fit (greater than the upper asymptote or below the lower asymptote) are highlighted in yellow.

The DRG® Hepcidin 25 bioactive ELISA (EIA-5258) is an enzyme immunoassay for the measurement of Hepcidin-25 in serum and plasma. This analysis calculates concentrations using a Four Parameter Logistic fit in accordance with the kit instructions. The standard data points (concentration vs. measurement) are plotted on semi-log axes and a 4PL curve is fit through the average of the replicated standards. The concentrations of the samples are determined from the fit with any specified dilution factors applied. The %CV, Standard Deviation and Standard Error are calculated for each replicated sample. Samples outside the range of the standards or the fit (greater than the upper asymptote or below the lower asymptote) are highlighted in yellow.

The DRG® Dihydrotestosterone (DHT) ELISA (EIA-4132) is an enzyme immunoassay for the measurement of DHT in human serum. This analysis calculates concentrations using a Four Parameter Logistic fit in accordance with the kit instructions. The standard data points (concentration vs. measurement) are plotted on semi-log axes and a 4PL curve is fit through the average of the replicated standards. The concentrations of the samples are determined from the fit with any specified dilution factors applied. The %CV, Standard Deviation and Standard Error are calculated for each replicated sample. Samples outside the range of the standards or the fit (greater than the upper asymptote or below the lower asymptote) are highlighted in yellow.

The DRG® Testosterone ELISA is an enzyme immunoassay for the quantitative in vitro diagnostic measurement of Testosterone in serum and plasma. This analysis calculates concentrations using a Four Parameter Logistic fit in accordance with the kit instructions. The standard data points (concentration vs. measurement) are plotted on semi-log axes and a 4PL curve is fit through the average of the replicated standards. The concentrations of the samples are determined from the fit with any specified dilution factors applied. The %CV, Standard Deviation and Standard Error are calculated for each replicated sample. Samples outside the range of the standards or the fit (greater than the upper asymptote or below the lower asymptote) are highlighted in yellow.
