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.
