Drug Testing Laboratory Practice Test

What is the required floor area for a confirmatory laboratory?

5 square meters 10 square meters 15 square meters 20 square meters

Correct Answer:

10 square meters

Explanation:

The essential point is the minimum space needed to conduct confirmatory testing safely and efficiently. A confirmatory lab typically houses instruments like GC-MS or LC-MS/MS and requires space for sample prep, preparation of standards and reagents, waste handling, and clear movement around benches and equipment. Ten square meters provides enough bench area and instrument footprint with adequate clearance for safe operation and to prevent cross-contamination or congestion. A smaller space, such as five square meters, would be too cramped for proper workflow and safety. Larger areas, like fifteen or twenty square meters, exceed the minimum requirement but may be used in bigger facilities; the stated minimum you’re expected to know is ten square meters.
