Which of the following is a common disadvantage of lab testing?

• A. Expensive/small pool/time consuming
• B. Not costly
• C. Broad generalization
• D. Quick results

Answer: (A)

Lab testing often provides precise, controlled measurements, but it comes with notable downsides: it tends to be expensive because of the equipment, facilities, and specialized staff required; it usually involves a small pool of participants due to costs and logistics, which limits how well the results apply to a broader population; and the process is time consuming because of setup, calibration, and data analysis. These factors together make expense, a small sample size, and longer turnaround common disadvantages of lab testing. Phrases suggesting it isn’t costly, yields quick results, or generalizes broadly describe advantages or outcomes that don’t match how lab testing typically works.
