Resources

External links for this lesson. All checked to load from a plain request as of the date this page was written. (Note: eCFR’s own site — ecfr.gov — blocks automated/proxied traffic with a bot check in this repo’s build environment, even though a human browser reaches it fine; the regulation text quoted in this lesson comes from eCFR’s public Versioner API instead, and the links below use verified-loading mirrors of the same official text.)

• Cornell LII: 21 CFR 610.40, current text — Cornell Law School’s Legal Information Institute mirror of the infectious-disease test requirements quoted throughout this lesson, including the release-restriction and reactive- result provisions. Use this to check the current text, since the copy in this repo’s sources/ folder is a dated snapshot.

• Cornell LII: 21 CFR 606.40, current text — the facilities regulation that requires a designated quarantine storage location, quoted in this lesson’s “actual text” section. Same use case: check for amendments against the dated snapshot in sources/.

• Cornell LII: Title 21, Part 610 browse index — the full general biological product standards part this lesson’s testing citation sits inside, including § 610.41 (donor deferral on a reactive result) and § 610.46–.47 (lookback and consignee notification procedures), which this director-level lesson names but doesn’t quote — your Quality Analyst will cite these directly when a reactive result actually occurs.

• GovInfo: Code of Federal Regulations — the U.S. Government Publishing Office’s official, legally authoritative annual CFR archive. Use this for the official, dated, legally citable version of a specific year’s text — for example, to confirm exactly what 610.40 said on the date of a past inspection or a reactive-result investigation.
