Drug Rate Response Curve
In drug assays the rate response decreases with increasing hapten (drug) concentration.
Figure 3.6 illustrates the rate response for several test samples with various hapten
concentrations. The magnitude of the rate response decreases from test sample A to
test sample E. Sample E has a very low rate response indicating a high hapten
concentration in the sample.

Drug Rate Response Curve
1. X = Increasing free hapten (drug) concentration
2. Y = Peak rate of scatter
3. A-E represent peak rate values at varying free hapten levels.
Specific antibody and drug conjugate remain at constant levels.
