Which type of analyzer offers random-access capabilities?

• A. Discrete analyzers
• B. Continuous-flow analyzers
• C. Centrifugal analyzers
• D. None of these

Answer: (A)

Random-access testing means you can start an analysis on a sample whenever it’s loaded, without waiting for a whole batch of samples to be ready. Discrete analyzers are built so each patient specimen is processed in its own cuvette or reaction chamber, with reagents added and results read independently. This design lets you run urgent or STAT samples immediately and add new cases as they come, without delaying others. In contrast, continuous-flow analyzers handle samples in a flowing stream and process them in sequence; they’re optimized for high throughput but typically operate on a batch or queued manner, which makes immediate, per-sample access less flexible. Centrifugal analyzers perform tests on rotor wells in batches during a cycle, so they’re also more batch-oriented rather than random-access.
