Enzyme immunoassay (EIA) for the quantification of 11-dehydro Thromboxane B2 - Monoclonal. This method plots %B/B0 for the standards versus 11-dehydro TXB2 concentration using linear (y) and log (x) axes and performs a 4-parameter logistic fit. Sample positions with %B/B0 values greater than 80% or less than 20% are highlighted in yellow. These samples should be re-assayed as they generally fall out of the linear range of the standard curve.
