What are laboratory services?

• A. Diagnostic tests and procedures performed in a laboratory to analyze samples from patients.
• B. Therapy sessions.
• C. Nursing care at the bedside.
• D. Rehabilitation services.

Answer: (A)

Laboratory services involve diagnostic tests and procedures performed in a laboratory to analyze samples from patients. These tests examine specimens such as blood, urine, or tissue to help diagnose conditions, monitor disease, or guide treatment decisions. They are carried out by laboratory professionals in hospital, clinic, or reference labs, and the results inform clinicians about a patient’s health status.

This description fits because it captures the testing and analytical work done on patient samples to inform care. The other options refer to different kinds of care—therapy sessions, bedside nursing, and rehabilitation services—that support treatment but are not laboratory testing. Examples of laboratory services include complete blood counts, metabolic panels, cultures, and pathology analyses.
