Quantitative in vitro assay for human IgM rheumatoid factors (autoantibodies of the IgM class against human IgG) in serum or plasma.
This method calculates concentration of antibodies in the serum samples using point-to-point plotting of the extinction values measured for the 3 calibrators (standards) against the corresponding units (linear/linear). Samples greater than the first calibrator are marked as “> Standard1”.
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...
