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 606.121, current text — Cornell Law School’s Legal Information Institute mirror of the container label requirements quoted throughout this lesson, including the full, unabridged text of the machine-readable labeling requirement this lesson excerpts. Use this to check the current text and to see the product-specific label content (Whole Blood, Red Blood Cells, Plasma, Source Plasma, autologous units) this director-level lesson didn’t quote in full.

• Cornell LII: 21 CFR 610.53, current text — the dating-period table this lesson draws from to show how one donation’s components expire on different schedules. Same use case: check for amendments against the dated snapshot in sources/.

• ICCBBA — the nonprofit standards organization that develops and administers ISBT 128, the barcode labeling standard this lesson covers in full. Use this as the primary source for ISBT 128 itself: what it is, what it covers, and how ICCBBA governs it — remember that everything on this site is industry-standard material, not FDA regulation or guidance, per this lesson’s regulation-versus-standard distinction.

• 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 606.121 said on the date of a past inspection or a labeling deviation investigation.
