Drug Test Information publishes educational material about laboratory testing, workplace programs, regulated industries, medical care, legal processes, and anti-doping. Because an inaccurate statement can affect health, employment, eligibility, or legal decisions, every page should make its scope, evidence, limitations, and review date clear.
Our editorial principles
- Accuracy: Claims should be supported by current, authoritative evidence.
- Clarity: Technical terms are explained in plain language without erasing important limits.
- Independence: Commercial interests do not determine conclusions or placement.
- Transparency: Sources, review dates, conflicts, and meaningful corrections are disclosed.
- Safety: Content does not provide instructions for evading, adulterating, or defeating legitimate testing.
How an article is developed
- Define the reader, question, jurisdiction, and testing context.
- Search for controlling rules and primary sources.
- Compare current agency, laboratory, medical, and legal guidance.
- Draft with distinctions between screening and confirmation, detection and impairment, general rules and exceptions.
- Check internal links, citations, dates, and reader actions.
- Review for medical, legal, or technical risk before publication.
Source hierarchy
We prefer statutes, regulations, court opinions, agency guidance, official program manuals, consensus standards, systematic reviews, clinical guidelines, and peer-reviewed research. Manufacturer material may explain a product but is not treated as independent evidence. Search snippets, unsourced charts, and anonymous posts are not sufficient support for material claims.

Medical and legal boundaries
General education cannot diagnose a person, interpret an individual result without the complete record, create an attorney-client relationship, or replace a controlling policy. Medical pages are reviewed against clinical guidance and emphasize appropriate professional care. Legal pages identify jurisdiction and avoid presenting general information as personalized legal advice.
Updates and corrections
High-change pages are reviewed when a cited rule changes and on a scheduled cycle. Material errors are corrected promptly and, when useful to readers, explained on the page. Minor grammar, formatting, and link repairs may be made without a formal correction note.
See the corrections and updates policy.
Authorship and assisted tools
Drafting and research tools may assist with structure, comparison, and editing, but publication remains an editorial responsibility. Sources must be opened and checked, claims must be reviewed, and automated output is never treated as authority. Learn more in the authorship and AI transparency policy.
Feedback
Readers who identify a possible error should provide the page URL, disputed statement, supporting primary source, and date accessed. We evaluate corrections on evidence, not on whether a change benefits a particular product, laboratory, employer, or party.
