Click here​ to find the latest Student Discussion Document for December’s Clinical Case Study from Matthew S. Petrie, Kara L. Lynch, Alan H.B. Wu, Angela A. Steinhardt, and Gary L. Horowitz.

Dr. Lynch provided us with two exclusive questions that will not appear in the published version of the Case. We'd love to hear your answers to these questions in the comments section.

  1. Why would immunoassays designed to target the same class of drugs (i.e. amphetamines) exhibit unique affinities for various other chemical compounds?
  2. How might patients with kidney or liver disease be more prone to false positive/negative immunoassay screening results?
