The laboratory is certified as Biosafety Level 3 (BSL-3), which confirms that the facility meets or exceeds national standards, established by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), for bio-containment precautions required to isolate biological agents such as Tuberculosis (TB) in an enclosed facility. (Levels of containment range from the lowest biosafety level 1 to the highest at level 4.)

The laboratory provides quality clinical and environmental testing for the people of Fairfax County as well as a number of surrounding counties in Northern Virginia. The laboratory serves a range of clients including local health departments; the Fairfax-Falls Church Community Services Board; Adult and Juvenile Detention Centers; Court Services; Dulles International Airport; and national, regional and state parks.

The laboratory is located in the City of Fairfax at 10310 Layton Hall Drive, Fairfax, VA 22030 and can be reached by phone at 703-246-3218, TTY 711.
