Abstract: Methods for monitoring subject compliance with a prescribed treatment regimen are disclosed. In one embodiment, the method comprises measuring a drug level in fluid of a subject and normalizing said measured drug level as a function of one or more parameters associated with the subject. The normalized drug level is compared to a reference value and associated confidence intervals or to a concentration range. The reference value and associated confidence intervals and/or the concentration range may be normalized based on one or more parameters associated with subjects in a reference population.

Abstract: Methods for monitoring subject compliance with a prescribed treatment regimen are disclosed. In an embodiment, the method comprises measuring a drug level in fluid of a subject and normalizing the measured drug level as a function of one or more parameters associated with the subject. The drug level can be normalized using second order quantile regression. Embodiments of the methods can use both primary and secondary metabolites in the normalization; allow changing variance by dose; allow asymmetry in variance above and below the estimated median values; and/or use analytic variables with stable estimates, such as, for example, variables associated with the percentile for ?1 standard deviation, the percentile for 0 standard deviation, and the percentile for +1 standard deviation.
