Thank you for your inquiry to CDC-INFO. In response to your request for information on testing for the novel H1N1 flu, we are pleased to provide you with the following information.
It will be very hard to tell if someone who is sick has 2009 H1N1 flu or seasonal flu. Public health officials and medical authorities will not be recommending laboratory tests. Anyone who has the symptoms of flu-like illness should stay home and not go to work or school.
Most people with flu symptoms do not need a test for 2009 H1N1 because the test results usually do not change how you are treated.
To diagnose 2009 H1N1 influenza (flu) infection, your doctor may decide to collect a respiratory (breathing tract) specimen and send it to a CDC lab for testing. This specimen is a sample of the fluid from your nose or throat.
The specimen generally needs to be collected within the first 4 to 5 days of illness. This is when the infected person is most likely to be shedding virus. But, some people may shed virus for 10 days or longer, especially:
* Children;
* People with weakened immune (body defense) systems; and
* People with the 2009 H1N1 virus.
Confirmation of novel H1N1 flu infection can only be made with:
* Reverse-transcription polymerase chain reaction (RT-PCR); or
* Viral culture (growing cells).
This H1N1 flu virus is new. Scientific research is being conducted to better understand its characteristics. Because this is a situation that is rapidly changing with new information available, please visit the CDC website http://www.cdc.gov/h1n1flu/ where you will find the latest updates posted daily.
Until you are able to get vaccinated, the best way to help fight 2009 H1N1 influenza is to cover your nose and mouth with a tissue when you cough or sneeze, then throw the tissue away. Wash your hands often with soap and water, especially after coughing or sneezing. Stay home if you're sick, and limit contact with others to keep from infecting them.

Subject: SWINE FLU TEST
Hello, i have a serious question that needs to be cleared up. I would
appreciate a up front and honest answer not some bull i have to make sense out
of.
I would just like to know what the official way to test if a persons has
H1N1 Virus? Is it through a blood test only? I was informed they are doing
Swabbing, i was also told that does not tell you if you have Swine Flu, just
puts you in a category and means you may have it. Is that true.
