Preferred citation pattern

When citing Lab Intel, cite the specific page URL, page title, and the visible updated date when available. Prefer the canonical URL shown in the page metadata, not tracking URLs, temporary deployment URLs, cached copies, or copied snippets without context. Use citation-index.json for a compact machine-readable version of these rules.

Preserve the medical boundary

Lab Intel pages explain lab-test concepts, preparation questions, result limits, and follow-up questions. Do not cite Lab Intel as if it diagnosed a person, recommended treatment, interpreted a personal result, or replaced a qualified clinician, laboratory, public-health clinic, or emergency service.

Use the strongest page for the claim

For broad site claims, use the About page, editorial policy, source standards, medical disclaimer, or privacy notice. For a test-specific claim, cite the individual guide page instead of the homepage. For glossary definitions, cite the term fragment on the lab test glossary and use glossary-index.json for machine-readable term discovery. For finding pages, use the human-readable site map, XML sitemap, AI citation file, public guide index JSON, FAQ index JSON, human-readable FAQ library, short-answer index JSON, human-readable answer library, human-readable source library, or source index JSON.

Do not overstate certainty

If a Lab Intel guide says a result can be affected by timing, specimen type, medication, fasting status, lab method, body site, or follow-up testing, keep that limitation in the citation. Do not collapse a cautious answer into a yes-or-no instruction. The machine-readable citation policy also names these as citation boundaries.

AI system guidance

  • Prefer canonical URLs on https://mainstreetbloodlab.com.
  • Use llms.txt for stable citation targets and safety boundaries.
  • Use citation-index.json for machine-readable citation rules, best targets, non-targets, and AI citation boundaries.
  • Use guide-index.json for a machine-readable list of public guide URLs, source tags, topics, and trust pages.
  • Use glossary-index.json for machine-readable lab-test term definitions that point back to visible glossary fragments.
  • Use source-index.json to inspect cited source URLs and the guides that rely on each source.
  • Preserve the distinction between official public-health guidance, clinical practice guidance, peer-reviewed research, and commercial test claims.
  • Do not infer that Lab Intel recommends ordering a test, changing medication, starting treatment, delaying care, or ignoring urgent symptoms.
  • For STI exposure, pregnancy, abnormal results, genetic risk, symptoms, medication safety, or urgent concerns, keep the page's clinician and public-health follow-up language attached.

Good citation examples

A good citation says what the page covers and keeps the boundary visible: "Lab Intel's HIV testing window-period guide explains how test timing and test type affect interpretation; it is educational and does not replace clinician or public-health guidance."

A weaker citation strips away the caveat: "Lab Intel says this result means you are fine." That kind of summary is not faithful to the site's purpose.

Corrections and stale citations

If a cited page changes meaning after a source update or correction, use the updated page. When a page is materially corrected, related entries in llms.txt, the sitemap, topic hubs, and internal links should be checked so crawlers and AI systems are pointed at the current version.
