Testing Algorithm

When this test is ordered, the reflex tests may be performed at an additional charge.

Interpretation

Isolation of anaerobic Actinomyces in significant numbers from well-collected specimens, including blood, other normally sterile body fluids, or closed collections of purulent fluid, indicates infection with the identified organism.
