ABPath Clinical Informatics Subspecialty Certification Examination Practice Test

Clinical informatics applies information science and technology to clinical care and laboratory operations. The available practice material uses pathology and laboratory examples involving software validation, terminology, data exchange, patient matching, risk-model assessment, privacy controls, and continuity planning during system outages.

About the ABPath Clinical Informatics Subspecialty Certification Examination Exam

The questions call for decisions about how information systems preserve meaning and support safe workflows. They address software testing, including checking requirements and detecting regressions after changes; controlled vocabularies and terminology services that link local display terms to stable concepts; and coded-result exchange between systems with different code sets. Other scenarios involve matching records across sites without confusing local identifiers, evaluating calibration by comparing predicted risks with observed outcomes, and reducing confounding in workflow studies. Operational judgment includes planning laboratory downtime procedures and setting safeguards before sensitive data are stored in a cloud service. These tasks connect technical choices with reliable reporting, data integrity, patient privacy, and laboratory service continuity.

Sample Practice Questions

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

Question 1

A laboratory is reviewing a proposed software change that could affect patient-result display. Which activity best helps determine whether the change meets its stated requirements?

  1. AAcceptance testing with predefined criteria and representative user workflows
  2. BChecking only whether the application starts on a developer's computer
  3. CWaiting for users to report problems after the change is fully deployed
  4. DReviewing the vendor's marketing description without testing the configured system
Show answerCorrect answer: A

Acceptance testing checks the configured system against predefined requirements using realistic workflows. It provides evidence that the change behaves as intended before it is relied on in routine operations.

Question 2

A hospital laboratory is replacing a long-running application. Staff need to confirm that key workflows still function after the change. Which testing strategy is designed to check that previously working functions have not been broken by new changes?

  1. ARegression testing
  2. BExploratory data mining
  3. CA one-time user satisfaction poll
  4. DDatabase normalization
Show answerCorrect answer: A

Regression testing reruns relevant tests after changes to detect unintended effects on existing functionality. Other activities may be useful, but they do not specifically test whether previously working behavior remains intact.

Question 3

A clinical informatics team is assessing whether a new workflow improves the time required to complete laboratory orders. Staff performance may differ by experience level. Which study practice best helps reduce the effect of this confounding factor when assigning participants to workflow groups?

  1. ARandom assignment, with stratification by experience if appropriate
  2. BAssign all experienced staff to the new workflow and all novice staff to the old workflow
  3. CAllow participants to choose the workflow they prefer and ignore the choice
  4. DMeasure completion time only for the fastest participant in each group
Show answerCorrect answer: A

Random assignment helps balance both measured and unmeasured participant characteristics across groups. Stratification can further help ensure important characteristics, such as experience, are represented comparably in each group.

Question 4

A laboratory is adopting a controlled vocabulary for organisms identified in culture. What is the main benefit of using a terminology with stable, unique concept identifiers?

  1. AIt guarantees that every laboratory uses identical culture methods
  2. BIt supports consistent representation and exchange of organism concepts across systems
  3. CIt replaces the need to record specimen source
  4. DIt ensures that all organism names are clinically significant
Show answerCorrect answer: B

Stable concept identifiers help systems represent and exchange the same organism concept consistently, even when display terms or local labels differ. They do not standardize laboratory methods or determine clinical significance.

Question 5

A laboratory is comparing a locally developed risk score with an established score in a new patient population. Which assessment most directly addresses whether predicted probabilities agree with observed event frequencies?

  1. ACalibration assessment
  2. BAssessment of software response time
  3. CInter-rater agreement for specimen labeling
  4. DA count of how many variables each score uses
Show answerCorrect answer: A

Calibration evaluates agreement between predicted risks and observed outcome frequencies. Discrimination, a different property, concerns how well a score separates people who do and do not experience the outcome.

Question 6

A pathology service is planning downtime procedures for an LIS outage. Which preparation most directly supports safe continuity of laboratory operations?

  1. ARely on staff to improvise documentation during the outage
  2. BMaintain tested procedures for specimen tracking, result documentation, and later reconciliation
  3. CDisable all identification checks until the system returns
  4. DDiscard work performed during the outage after recovery
Show answerCorrect answer: B

A tested downtime plan should preserve specimen identification and tracking, document work performed while systems are unavailable, and define how records are reconciled after restoration. This reduces risks of lost, duplicated, or misattributed work.

Question 7

A laboratory data warehouse combines results from two sites. The same patient may have different local identifiers at each site. Which step is essential before treating the records as belonging to one person?

  1. AUse a validated patient-matching process with appropriate identifiers and governance
  2. BAssume identical names always indicate the same patient
  3. CMerge records based only on matching birth year
  4. DRemove identifiers before attempting any linkage
Show answerCorrect answer: A

Cross-site linkage requires a governed, validated identity-resolution approach that evaluates appropriate identifiers and manages uncertain matches. Names or birth year alone can produce both false matches and missed matches, potentially corrupting analyses and clinical records.

How to use this practice test

Work through the free question bank in sessions of up to 20 randomly selected questions. Use each result to identify concepts that need closer review, such as regression testing, terminology mapping, calibration, record linkage, or downtime planning. Revisit missed questions by explaining why the selected informatics approach fits the scenario.

Preparation tips

  • Distinguish requirements testing, regression testing, and other validation activities; identify what each can establish about a software change.
  • Compare local codes, standard vocabularies, and terminology services, focusing on concept identifiers, mappings, and preserving meaning across systems.
  • Practice separating patient identity matching from local record-number matching when laboratory data are combined across sites.
  • Review calibration as agreement between predicted probabilities and observed event frequencies, and consider how study assignment can limit confounding.
  • Draft a laboratory downtime checklist that addresses safe result handling, workflow continuity, and access to sensitive information.
