All approaches to automation are capable of which function?

• A. Batch testing
• B. Continuous flow
• C. Random Access
• D. Parallel testing

Answer: (A)

In automation, batching is the basic way most systems operate: grouping several samples together and processing them in one run. This fits lab workflows because instruments are typically optimized to handle a set of tests on a batch of specimens, maximizing throughput and minimizing idle time between samples. Whether a platform is a simple bench analyzer or part of a larger high‑throughput line, you can usually queue a batch of samples, run the defined assays, and obtain results for all of them together.

The other modes describe specific operational designs that not every automated system supports. Continuous flow implies a steady stream of samples moving through the process, which some setups don’t implement. Random access means selecting and testing samples in any order as they arrive, which isn’t universal across all automation architectures. Parallel testing involves multiple tests being run at the same time, which again depends on the instrument’s design and capacity.

So, batching is the most universally applicable function across automation approaches.
