local lab tests neg - 95% freq. CDC confirm positive

Is this true?

"This child definitely has influenza. The question is whether it's the new H1N1 strain," said Dr. Fleming. "Experience around the country has been that when tests that our laboratories do are negative as they have been, that 95 percent of the time, when the confirmatory test is done at CDC, that confirmatory test is shows that it is Influenza A-H1N1."http://www.kpax.com/Global/story.asp?S=10286475
 
Re: local lab tests neg - 95% freq. CDC confirm positive

From Kent Nickel -
ghost RN, my interpretation of that would be if someone presents with true influenza like illness and has a negative rapid test at the local hospital but is then forwarded to a state lab. The state lab then gets a positive type A with their more comprehensive reagents but get a negative when they try and type it with their H3N2 or H1N1 sera. At this point it would seem to have a 95% chance of being positive at CDC for novel H1N1 (2009). I think CDC was going to be shipping the specific novel H1N1 (2009) pcr primers to state labs soon.....
