A doctor trained in Clinical Lab. Man. can handle how many drug screening laboratories?

• A. 10
• B. 5
• C. 3
• D. 8

Answer: (A)

Regulatory limits govern how many drug screening laboratories a physician with clinical laboratory management training may supervise. Drug screening facilities require close, ongoing oversight to ensure quality control, proper chain of custody, and accurate reporting. To keep supervision effective across sites, regulators set a cap on the number of laboratories under a single supervisor. The correct choice reflects the maximum permissible by regulation, representing the upper bound of what can be overseen by one physician. Lower counts could be allowed, but they do not indicate the upper limit. If more laboratories exist than what the cap allows, additional qualified supervision must be arranged to maintain standards.
