Why donor-to-recipient lookback is the product
In a blood centre or tissue bank, the 'lot' is a donor. Every unit you collect, process and distribute has to be traceable forward to every recipient and backward to every donor — in seconds, not days.
Under 21 CFR 1271 (HCT/Ps), 21 CFR 606 (cGMP for Blood) and the AABB / AATB / FACT-JACIE standards that overlay them, every donation is a regulated batch with its own donor-eligibility determination, its own IDM (infectious-disease marker) panel, its own processing record, and its own consignee list. A single reactive donor — HIV, HCV, HBV, HTLV, Treponema pallidum, WNV, Zika, Chagas — fires a lookback that must touch every component made from that donation, every recipient transfused or grafted, and every facility that received product.
The hazards that drive enforcement are unambiguous: a unit released before IDM testing cleared; a deferred donor whose previous donation wasn't quarantined; an ISBT 128 label re-printed without an audit trail; a cold-chain excursion caught at month-end instead of at the moment of excursion; an SOP-of-record that doesn't match SOP-actually-followed.
V5 Ultimate builds the donor record and the processing record together. Quarantine is hard-gated until IDM clears. Lookback is a query. Cold chain is a stream. AABB, AATB, FACT-JACIE and FDA BIMO inspections all read the same record.
