AATB StandardsAmerican Association of Tissue Banks — Standards for Tissue Banking
AATB Standards for Tissue Banking are the voluntary accreditation standards maintained by the American Association of Tissue Banks. They sit on top of 21 CFR 1271 and go further in areas FDA leaves to the establishment — donor risk assessment, processing validation, sterility assurance, and the technical detail of musculoskeletal, skin, cardiovascular, ocular, and birth-tissue operations.
01What the AATB Standards are
The AATB Standards for Tissue Banking are the voluntary quality, technical, and operational standards published by the American Association of Tissue Banks. They cover the full tissue-bank value chain: donor screening and consent, recovery, processing, packaging, labelling, storage, distribution, complaints, and adverse events. The standards are organised into general standards applicable to all tissue types, plus type-specific standards for musculoskeletal, skin, cardiovascular, reproductive, birth tissue, and ocular tissue (in coordination with EBAA).
AATB accreditation is voluntary, but in practice every US tissue bank with meaningful clinical distribution is accredited. Hospitals, surgery centers, and dental practices increasingly will not source allografts from non-accredited establishments — and most insurance and group-purchasing arrangements require AATB accreditation as a precondition.
02AATB vs FDA — different layers of detail
FDA inspects against 21 CFR 1271 — Subpart C (donor eligibility), Subpart D (cGTP), and Subparts E/F (adverse events, inspection). AATB assesses against the Standards — a much more detailed technical overlay covering things FDA cGTP leaves to the establishment: validated processing (sterilisation dose, residual moisture, mechanical testing of musculoskeletal allografts), bioburden monitoring, packaging seal integrity, finished-product testing, and the technical specifications of each tissue type.
03Operational areas AATB drives
| Area | What AATB requires |
|---|---|
| Donor screening | Standardised donor risk assessment interview, physical assessment, medical record review beyond 1271 minimums. |
| Recovery | Recovery technician qualification, aseptic technique validation, recovery-site environmental controls, time limits from death to recovery. |
| Processing | Validated processing methods, in-process bioburden monitoring, controlled environments classified to ISO 14644 where applicable. |
| Sterilisation | Validated sterilisation methods (gamma, e-beam, supercritical CO₂, others) with documented Sterility Assurance Level. |
| Packaging | Validated container-closure, seal-strength testing, package integrity monitoring. |
| Labelling | ISBT 128 required for accreditation. Type-specific labelling per AATB technical appendices. |
| Storage | Controlled storage temperatures with continuous monitoring and alarming. Quarantine separation enforced. |
| Distribution | Validated shipping containers, temperature monitoring in transit for temperature-sensitive products, chain of custody. |
| Adverse outcomes | Investigation, root-cause analysis, reporting to FDA (Form 3486) and AATB Tissue Outcomes Database (TODP). |
04Accreditation cycle
- Application and document review — SOPs, organisation chart, quality manual, training records.
- On-site assessment by trained AATB inspectors (volunteers from accredited peer institutions plus AATB staff). Typically 3–5 days covering all activities at the establishment.
- Findings classified by severity. CAPA plans due within defined timeframes; closure requires evidence review by AATB.
- Accreditation granted for three years, with annual reporting and interim updates required.
- Re-accreditation involves a full repeat assessment.
Frequently asked questions
Q.Is AATB accreditation required by law?+
Not by federal law. But many state tissue-bank laws and most clinical procurement arrangements (hospitals, surgery centers, GPOs) require it in practice.
Q.How does AATB relate to EBAA for eye banks?+
AATB and the Eye Bank Association of America (EBAA) maintain coordinated standards. Most US eye banks are EBAA-accredited; AATB recognises EBAA accreditation as equivalent for ocular tissue.
Q.Does AATB cover birth tissue?+
Yes — AATB has dedicated standards for birth-tissue establishments covering amniotic membrane, umbilical cord, and placental tissue, including specific requirements around the 361 / 351 line and donor consent.
Q.What's the AATB Tissue Outcomes Database (TODP)?+
TODP is AATB's adverse-outcome surveillance system. Accredited establishments report tissue-related adverse outcomes for trend analysis and signal detection — a sector-wide safety net on top of FDA Form 3486 reporting.
Q.Can a single establishment be both AATB and AABB accredited?+
Yes — many cord-blood banks and combined blood/tissue centres hold both. The Standards overlap heavily; most establishments maintain a single quality system mapped to both.
