Laboratory Information Systems (LIMS) interview questions

Sample identity, workflow traceability and instrument-to-data integration.

6 questions, each with a worked answer

How would you preserve sample identity across laboratory instrument integrations? Intermediate Scenario
What should be tested when a LIMS workflow is changed? Fundamentals Concept
What should happen when an instrument returns a result for an unknown sample ID? Intermediate Scenario
How would you design immutable audit trails in a LIMS? Advanced Scenario
What is the difference between configuration change and validated workflow change? Intermediate Concept
How do you reconcile duplicate or conflicting sample identifiers? Advanced Scenario

About Laboratory Information Systems (LIMS)

A laboratory information management system (LIMS) tracks samples, tests, results and workflows across a laboratory. It keeps sample identity and chain of custody intact, links results to instruments and methods, and supports reporting. In regulated labs it must meet data integrity expectations such as audit trails and access control.

Configuring and validating a LIMS well depends on understanding how the lab actually works.

Fundamentals: 1
Intermediate: 3
Advanced: 2

What these questions test

Configure sample traceability: Model samples, movements, tests and permissions with an audit trail.
