What the CTBS Exam Covers

The CTBS examination tests candidates across six primary knowledge domains:

Tissue banking fundamentals: Donor screening criteria, eligibility determination, medical and social history review, infectious disease testing requirements, and contraindications to donation.
Recovery procedures: Aseptic technique in surgical recovery, sterile field maintenance, instrument handling, tissue documentation, and recovery site protocols.
Processing and preservation: Cryopreservation techniques, freeze-drying (lyophilisation), gamma irradiation, electron beam sterilisation, packaging specifications, and labelling standards.
Distribution and storage: Cold chain management, storage temperature requirements, quarantine and release procedures, and shipping documentation.
Quality management systems: SOPs, deviation reporting, CAPA processes, internal audits, and accreditation requirements.
FDA regulations and AATB standards: 21 CFR Parts 1270 and 1271, AATB Standards for Tissue Banking, adverse event reporting, and inspection readiness.

Key Topics in This CTBS Practice Test PDF

The practice questions in this PDF are organised by domain and reflect the depth of knowledge tested on the actual CTBS examination.

Donor Screening and Eligibility

Questions cover the evaluation of donor medical and social history, review of medical records, physical assessment, serological testing requirements (HIV, HBV, HCV, HTLV, syphilis), NAT testing windows, and exclusionary criteria under AATB Standards and FDA 21 CFR 1271.

Surgical Recovery and Aseptic Technique

Candidates are tested on maintaining a sterile field during surgical recovery, gloving and gowning protocols, instrument sterilisation methods, recovery documentation, specimen labelling at time of recovery, and chain of custody initiation.

Processing, Preservation, and Sterilisation

Topics include the principles and limitations of cryopreservation, lyophilisation cycle validation, gamma irradiation dose selection and dose-mapping, packaging integrity testing, and final product labelling compliance with 21 CFR 1271.370.

Quality Management and CAPA

Questions on quality systems include writing and reviewing SOPs, classifying and documenting deviations, root cause analysis methods, corrective and preventive action (CAPA) planning, trend analysis, and preparation for AATB accreditation inspections.

FDA Regulations and Chain of Custody

Chain of custody documentation is critical in tissue banking. Questions cover donor ID traceability from recovery through distribution, adverse reaction reporting timelines, FDA Form 3500A requirements, and record retention obligations under 21 CFR 1271.
