How many samples shall be submitted?

How many samples shall be submitted?

• A. Two samples
• B. Four samples
• C. Five samples
• D. Three samples

Answer: (D)

Submitting samples in a triplicate arrangement is a common practice to balance reliability and efficiency. It provides multiple opportunities to run the analysis, with a built-in check and a reserve for re-testing, without slowing the process. This setup helps identify outliers and account for variability in sampling and handling, giving enough data to gauge consistency across runs. A smaller set offers less redundancy, whereas a larger set increases cost without proportional benefit for standard tasks. Therefore, using a triplicate set is the preferred approach to achieve reliable conclusions with reasonable resources.
