ASCP BOC Qualification in Biorepository Science (QBRS) Examination Practice Test

Biorepository science links specimen collection, processing, storage, and distribution with the records needed to preserve specimen quality and research value. This QBRS practice page samples practical decisions involving specimen traceability, handling, documentation, information security, collection representativeness, and evaluation of repository services.

About the ASCP BOC Qualification in Biorepository Science (QBRS) Examination Exam

Repository work depends on consistent procedures and reliable data across a specimen’s lifecycle. Staff must document collection and processing details, use coded identifiers that support traceability without exposing direct personal identifiers, and maintain records that help users interpret specimens acquired under different protocols. Storage-location data must be specific enough to retrieve material accurately, while receipt procedures for shipments such as dry-ice-packed frozen specimens must protect both staff and specimen integrity. Other practical judgments include responding to missing metadata, assessing whether a collection reflects its intended population, selecting fit-for-purpose DNA quantification methods, and considering operational feasibility before adding a specimen type. Information security controls and clear standard operating procedures help protect records and support reproducible repository practice.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A repository is reviewing whether its electronic records are protected against unauthorized alteration. Which control most directly supports this goal?

  1. AGive all staff the same shared account for convenience
  2. BUse role-based permissions and retain an audit trail of record changes
  3. CAllow users to edit records without recording who made the change
  4. DPrint records periodically and delete the electronic versions
Show answerCorrect answer: B

Role-based access limits editing to authorized users, while an audit trail records changes and supports accountability and review of the data lifecycle.

Question 2

A repository wants to determine whether its collection is representative of the population it intends to serve. Which information is most useful for evaluating this question?

  1. AOnly the total number of specimens in storage
  2. BRelevant characteristics of the contributing population and how participants or specimens were recruited
  3. CThe number of freezer shelves assigned to the collection
  4. DThe date the repository purchased its database software
Show answerCorrect answer: B

Assessing representativeness requires understanding the source population, recruitment or enrollment approach, and relevant characteristics of contributors. A large specimen count alone does not show that a collection reflects its intended population.

Question 3

A repository is selecting a method to estimate the concentration of DNA in extracted specimens. Why might a fluorometric assay be preferred over absorbance measurement when samples are dilute or contain contaminants?

  1. AIt measures fluorescence from a dye that binds preferentially to the target nucleic acid
  2. BIt determines the exact sequence of every DNA molecule in the sample
  3. CIt guarantees that the DNA will perform successfully in every downstream assay
  4. DIt measures only the total mass of all dissolved substances
Show answerCorrect answer: A

Fluorometric methods use dyes with affinity for specific nucleic acids and can provide more selective quantification, particularly at low concentrations. They do not establish sequence or guarantee downstream performance.

Question 4

A biorepository is drafting a standard operating procedure (SOP) for a recurring specimen-handling task. Which feature makes the SOP most useful for consistent practice?

  1. AIt describes the task in clear, ordered steps and identifies responsibilities and records to complete.
  2. BIt lists only the scientific rationale, leaving each operator to choose the workflow.
  3. CIt applies only to the staff member who originally wrote it.
  4. DIt avoids revision dates so users can compare copies more easily.
Show answerCorrect answer: A

A useful SOP gives personnel clear, repeatable instructions, defines relevant responsibilities, and specifies associated documentation. Controlled review and revision help keep the procedure current.

Question 5

A repository has accumulated specimens using several different collection protocols. Which practice best helps researchers interpret data derived from these specimens?

  1. AReplace the original protocol records with the repository's current preferred protocol
  2. BRecord the applicable protocol version and relevant deviations for each specimen or collection
  3. CAssume that specimens of the same type are interchangeable regardless of collection method
  4. DStore protocol information only in the memory of the staff who processed the specimens
Show answerCorrect answer: B

Protocol version and deviation records provide provenance needed to assess differences in collection and processing that may affect specimen characteristics or research results.

Question 6

A repository receives a shipment of frozen specimens packed with dry ice. Which handling practice is most appropriate during receipt?

  1. AAllow the shipment to warm until all contents can be inspected comfortably
  2. BPrioritize prompt inspection and transfer to suitable storage while following safe dry-ice handling procedures
  3. CPlace the specimens in a refrigerator overnight before assigning storage locations
  4. DDiscard the shipment because dry ice cannot be used for specimen transport
Show answerCorrect answer: B

Frozen specimens should be assessed and transferred promptly to storage conditions appropriate for their specified requirements, minimizing avoidable warming. Dry ice also presents cold-contact and carbon-dioxide hazards, so staff should follow applicable safety procedures and use appropriate protective equipment and ventilation.

Question 7

What information is most useful for linking a repository specimen to its processing history without placing direct personal identifiers on the tube?

  1. AA coded specimen identifier linked to a controlled record
  2. BThe participant’s full name written on the tube
  3. CThe collector’s personal phone number
  4. DA generic label such as “blood sample”
Show answerCorrect answer: A

A coded identifier can connect the physical specimen to controlled records containing relevant processing information while limiting direct identifiers on the container.

How to use this practice test

The free US Practice Tests bank contains 50 published questions; each session presents up to 20 random questions. Complete a session to see your results, then use missed items to identify which specimen-handling decisions, documentation practices, or repository concepts need closer review.

Preparation tips

  • For each specimen-handling scenario, map the sequence from receipt through processing and storage, noting which events and timestamps should be documented.
  • Practice distinguishing coded specimen identifiers from direct personal identifiers, and consider how each supports traceability or privacy.
  • Compare fluorometric DNA quantification with absorbance measurement, especially for dilute samples or extracts containing contaminants.
  • Review how collection and processing protocol differences affect interpretation, and identify metadata that would help researchers assess those differences.
  • For repository planning scenarios, list feasibility factors such as specimen availability, processing capacity, storage needs, and information-system support.
