Laboratory Testing for Novel Influenza A (H1N1) Virus

Effective September 1, 2009, influenza PCR testing at the University Hygienic Laboratory (UHL) will be limited to surveillance purposes and will not be used for diagnosing individual patients. The influenza tests available in the UIHC Microbiology Laboratory [influenza A/B antigen detection by direct fluorescent antibody (DFA) and respiratory virus culture] will detect novel influenza A (H1N1) as "influenza A." Testing may be ordered on EPIC using one of the following new panel:

DFA results are provided the same day if specimen is received by 2:30 p.m. Respiratory virus culture results are available in 48 h. Requests for "H1N1" or "swine flu" PCR will be interpreted as a request for the Influenza A/B detection panel. Specimens from hospitalized patients that are positive for influenza A will be sent to UHL for subtyping as novel H1N1, seasonal H1, or seasonal H3.

Specimen Collection: Transport specimens to the Microbiology laboratory (6004 BT) immediately on ice or refrigerate. From 2245 to 0700, deliver specimen to Specimen Control (6240 RCP) on ice. Questions regarding laboratory testing may be directed to Dr. Sandra Richter 6-2990 or Dr. Dan Diekema 4-5626.
