Tox In Focus delivers 1–2 page reference guides on specific drugs, drug classes, testing technologies, and validity concepts, the resource you reach for when you need to get smart on something fast, or explain it to someone else.
Every volume is a focused reference document: pharmacology, detection science, immunoassay gaps, clinical implications, and what the result actually means.
A single drug, drug class, testing technology, or validity concept, covered completely, without the surrounding noise.
Volumes are available to subscribers and by request. Contact Dr. Bundy to get access to existing volumes or request a topic.
Most clinical education on drug testing covers topics too broadly to be useful at the point of a specific decision, or too superficially to actually build understanding. Tox In Focus takes a different approach.
Each volume focuses entirely on a single topic: one drug, one drug class, one testing technology, one validity concept. The goal is a document that gives you everything you need to know about that specific thing, and nothing you don't, in 1–2 pages.
Volumes are written by Dr. William Bundy Jr., PharmD, and are available to subscribers or by direct request. Topics can also be requested; if your team needs a reference on something not yet in the series, reach out.
Individual substances or classes: pharmacology, detection windows, immunoassay performance, clinical implications, and result interpretation.
How specific test types work, what they detect, where they fail, and what confirmatory testing looks like, explained for clinical and legal contexts.
Creatinine, specific gravity, oxidizing adulterants, dilution: what the numbers mean, when to act on them, and when to look deeper.
If your team has a specific topic that isn't yet covered, contact Dr. Bundy to discuss a custom volume or request a future series entry.
Volumes are available by request. Reach out to get access to the existing series, request a specific topic, or ask about organizational subscriptions for your clinical team or program.
