New H1N1 test more precise in diagnosis
NEWS IN BRIEF — Posted July 12, 2010
Laboratories soon will be using a new, more sensitive test to diagnose human infections with the 2009 influenza A(H1N1) virus, according to the Centers for Disease Control and Prevention.
The CDC-developed test was authorized by the Food and Drug Administration in June. The diagnostic tool is used to isolate and amplify viral genetic material present in secretions taken from a patient's upper or lower respiratory tract, according to the CDC.
The test can detect human infections with the H1N1 virus with sensitivity and specificity greater than 96% for upper respiratory specimens. Multiple samples can be tested at the same time, and results can be provided within four hours.
The test is being shipped to public health labs and will replace a test used during the 2009 H1N1 pandemic, according to the CDC. Only labs that are qualified to test for H1N1 will receive the new diagnostic tool.
