Legionella and Pneumocystis Testing

Tuesday, July 10, 2018

Effective July 23, 2018, Laboratory Alliance of Central New York will no longer perform Legionella culture, DFA testing for Legionella or DFA testing for Pneumocystis in-house. Specimens with requests for these tests will be forwarded to our reference laboratory, ARUP. For Pneumocystis, the preferred replacement test is Pneumocystis jirovecii by PCR.

Specimen requirements remain unchanged. Legionella DFA test results will generally be available within 1 to 3 days. Pneumocystis PCR test results will generally be available within 3 to 5 days. Please note that Legionella culture results may take up to 5 to 7 days because of the extended bacterial incubation requirements.
