Which term describes 'Any test on any sample at any sequence' in automation?

• A. Random access
• B. Batch testing
• C. Parallel testing
• D. Sequential testing

Answer: (A)

The term describes the ability of an automated system to select any test for any sample in any order. This random access capability lets you load a sample and run a specific assay immediately, switch to a different test on the same or a different sample, or re-run tests without being forced into a fixed batch or a predetermined sequence.

Why this is the best fit: in batch testing, samples are processed together in a set group and follow a predefined sequence, which can delay urgent requests or reflex testing. In sequential testing, tests are performed in a fixed order for a set of samples, again limiting flexibility. Parallel testing means running multiple tests at the same time, improving throughput but not inherently allowing arbitrary ordering or selection of tests for individual samples. Random access uniquely captures the idea of doing any test on any sample at any sequence, enabling fast turnarounds for STAT needs and highly flexible workflows.
