Benefits of Different Flu Kits
Flu is a respiratory infection brought about by myriad viruses. The viruses gain access to your body from the air through your nose or mouth. Studies have revealed that there is a steady increase in the number of individuals contracting the infection. While it may pass as a not-so-serious illness to the average person, it may be pretty lethal to some demographic including newborns, senior citizens, as well as pregnant mothers. Lethal as it may seem, the good news is that there exist kits that can be used to detect it in good time for immediate medical attention. The use of the kits to detect viral influenza antigen has increased tremendously in recent times.
What does the test do?
Tests screen for influenza virus infection and can give you the result in not more than fifteen minutes. Relevant authorities have approved many tests and test kits. Rapid influenza Diagnostic test, for instance, makes use of an analyzer reader to a standard the results once you take the test.
Some rapid influenza diagnostic tests show variance in many ways including;
- Some are able to identify influenza A and B as well as distinguish between the two in a respiratory specimen.
- Others are able to identify influenza A and B antigens but do not distinguish between the two in the respiratory specimen.
- Most of the tests, however, can be used with an array of respiratory specimen types. The accuracy of the test, however, will greatly be influenced by the type of specimen collected.
Clinical considerations of testing when the prevalence of influenza virus is high and low
Low influenza prevalence translates into low positive predictive value (PPV). False positive tests are therefore a little more likely. Conversely, when the influenza prevalence is relatively low, the negative predictive value (NPV) is high. In this case, there is more likelihood of a negative result. The interpretation of a positive result by a clinician should take into account a couple of facts including the clinical characteristics of the patient as well as the prevalence of influenza in that demographic with which the patients being tested belongs.
In the same vein, when the prevalence of influenza is high, the NPV becomes low, and there is a likelihood of false negative results.
Selecting the tests
As you pick the best tests, the following factors should be at the back of your mind.
- The tests with high specificity as well as sensitivity will give high positive and negative predictive values, in that order.
- Tests that have been waived by the CLIA can be undertaken at the point of care
