Which facility performs tests on blood and body fluids?

• A. Hospitals
• B. Clinics
• C. Pharmacies
• D. Laboratories

Answer: (D)

Testing blood and body fluids requires precise technology, quality control, and trained personnel. A laboratory is the setting designed for this work, performing analyses such as chemical panels, complete blood counts, microbiology cultures, and tests on samples like blood, urine, and spinal fluid. The results support diagnosis, treatment decisions, and disease monitoring, and they come from standardized methods under regulatory oversight. While a hospital may house a laboratory or a clinic may collect samples, the activity of performing these diagnostic analyses is the domain of the laboratory.
