Active Viable air sampling is the most global in nature. It utilizes an instrument that draws ambient air and then directs the air stream at an attached agar plate for collection.
When placed in a room or in the primary engineering control, this test monitors the products of viables that are released into the air stream.
The objective of surface monitoring is to determine the presence of viable microorganisms on a variety of critical surfaces, including laminar airflow workbenches, floors, laboratory personnel and difficult-to-reach areas such as the interior of tubing and filling needles.
Fingertip testing is performed to evaluate the efficacy of compounding personnel’s hand washing and garbing techniques.
