<\/a>\nYou might be asking so what does this mean? There is no way for physicians to test specifically for the swine flu (Novel Influenza Type A (H1N1)) without a positive culture or RT-PCR performed by an approved laboratory. This means that you’ll be completely better or dead before you can find out whether or not you actually had the swine flu and not some other sub-type of the Type A virus. (Which includes the seasonal flu)
\n <\/strong><\/p>\n
According to the CDC, \u201cAt this time, there are only two FDA cleared assays for confirmation of novel influenza A(H1N1) virus infection, including the CDC rRT-PCR Swine Flu Panel assay; however, experimental rRT-PCR assays, not approved or authorized by FDA, may be able to detect novel influenza A (H1N1) virus infection.\u201d(source<\/a>)<\/strong><\/p><\/blockquote>\n
\nThe two CDC approved tests are \u201creal-time reverse transcriptase-polymerase chain reaction (rRT-PCR)\u201d <\/strong>and “laboratory analyzed viral cultures”<\/strong> but the only test physicians can use is the \u201cRapid influenza diagnostic tests (RIDTs)\u201d<\/strong>. I\u2019m not a physician so if you\u2019d like to know the details of each test you\u2019ll need to do some research (See the Links at the bottom of the page) or ask your physician. What is important is what the CDC has to say about each test.<\/p>\nRIDT\u2019s:<\/strong> According to the CDC website, \u201cNone of the currently FDA approved RIDTs can distinguish between influenza A virus subtypes (e.g. seasonal influenza A (H3N2) versus seasonal influenza A (H1N1) viruses), and RIDTs cannot provide any information about antiviral drug susceptibility.\u201d (Source<\/a>)<\/strong><\/p><\/blockquote>\n
<\/strong><\/p>\n
rRT-PCR Swine Flu Panel:<\/strong> \u201cThe rRt-PCR Swine Flu Panel test should be ordered to presumptively<\/strong> diagnose novel influenza A (H1N1) infection only.\u201d (Source<\/a>)<\/p>\n
Further, \u201cA positive test result from the rRt-PCR Swine Flu Panel indicates that the patient is presumptively<\/strong> infected with novel influenza A (H1N1).” (Source<\/a>)<\/p><\/blockquote>\n
According to Merriam-Webster’s Medical Dictionary, Presumptive<\/strong> is “expected to develop in a particular direction under normal conditions<\/strong>” (Source<\/a>)<\/p>\n
CDC had the following to say when comparing the RIDT’s (Only test physician can perform) and The rRt-PCR Swine Flu Panel test ,<\/p>\n
\u201cThese tests differ in their sensitivity and specificity in detecting influenza viruses as well as in their commercial availability, the amount of time needed from specimen collection until results are available, and the tests\u2019 ability to distinguish between different influenza virus types (A versus B) and influenza A subtypes (e.g. novel H1N1 versus seasonal H1N1 versus seasonal H3N2 viruses).\u201d<\/strong> (Source<\/a>)<\/p><\/blockquote>\n
I’m left with one VERY important question, What does the CDC consider a confirmed case of Swine Flu?<\/strong>
\nThe CDC uses the following guidelines: A confirmed case of novel influenza A (H1N1) virus infection is defined as a person with an influenza-like illness with laboratory confirmed novel influenza A (H1N1) virus infection by one or more of the following tests:<\/p>\n1. real-time RT-PCR<\/li>\n 2. viral culture<\/li>\n (Source<\/a>)
\nThe CDC has this to say about the real-time RT-PCR test, “If reactivity of real-time RT-PCR for influenza A is strong (e.g. Ct <30) it is more suggestive of a novel influenza A (H1N1) virus. Confirmation as novel influenza A (H1N1) virus by real-time RT-PCR was originally performed only at CDC, but at this time may be available in your state public health laboratory.” (Source<\/a>) What I’m left wandering is how something based on suggestion turns conclusive. I couldn’t find any information where the CDC elaborates.<\/p>\nThe CDC has this to say about Viral Cultures: “Isolation of novel influenza A (H1N1) virus is diagnostic of infection, but may not yield timely results for clinical management. A negative viral culture does not exclude<\/strong> infection with novel influenza A (H1N1) virus.” Seeing the word “Diagnostic” is a move in the right direction but I am a bit discouraged when they say a negative culture does not exclude an infection. My hopes are this leaves room for human error when collecting the cultures and isn’t proclaiming the culture test itself is flawed.<\/p>\n
So what exactly am I getting at? There is no way for a physician or health organization to definitively tell a patient whether they have H1N1, H3N2, or any other Influenza A sub-type (Which includes seasonal flu) when using readily available RIDT’s. The only diagnostic results come from the lengthy process of laboratory analyzed cultures and rRt-PCR swine flu panels.<\/p>\n
If you have any information you think I should add or anything you\u2019d like to say feel free to leave a comment.<\/p>\n
Will you be Taking the Swine Flu Vaccine when it’s made available?<\/a><\/h3>\n
