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.
If the entire plate was read then supply the measured value for each well. Alternatively, if only specific parts of the plate were read then list only those measured values. In this case an additional step is required: under the Microplate section below, select or create a layout which defines which wells were read and which were not. More...
A zero concentration value has been specified with a logarithmic x axis.
This is valid but means that you will not see the zero standard on the chart, also in certain cases it may result in a skewed fit. One alternative is to use a suitably low value, such as 0.01 instead of zero. More...
