The issue is important in diagnosing viral infections acute H5N1 bird flu will determine whether the patients in the test (on the basis of epidemiology and clinical research results) In order to keep an appropriate clinical samples and to use the appropriate test method. The World Health Organization (WHO) issued a definition of categories of suspects and confirmed cases of the H5N1 bird flu virus infection to the purpose of epidemiology and reporting [25] risk factors of H5N1 virus infection with direct physical contact, such as touching. Or within 1 m with poultry which illness or death in the weeks prior to onset of illness. [26-28] and to walk around in the market, selling the animals [28-30], but in some cases, it may be due to contact between humans to humans by themselves [32-34), so the infected bird flu H 5 N 1 should be considered in people with fever. • Acute respiratory failure In a country where illnesses cause high disease. The outbreak caused poultry H5N1 have occurred for those who have a past history of direct contact or close to poultry that are sick or dead poultry market has visited with life or people who have close contact (within 12 m) click New khakan diagnosis during your illness.Rokkhai bird flu (H5N1) in the beginning of a challenge because there are no specific symptoms of the disease, bird flu (H5N1) virus infection has not been case H 5 N 1 is specified in tourists as the seasonal influenza virus infections have been diagnosed in 25 (42%) from the 59 people who return to the United States with the song ...ัย H 5 N 1 [35] centers for disease control (CDC) Design guidelines for test cases that are suspected of being infected with the virus in the United States with people who have been infected with bird flu virus H 5 N 1 for patients who do not receive both a respirator and the nose, for example, the broom should sweep a sample appears with yield. High to detect H5N1 bird flu virus than to a nose or a diagnostic sample, for example, the cavity behind the nose, [37] but to detect viral RNA, or separate from, for example, the cavity behind the nose or nose of the critics for patients has been reported because of the H5N1 virus and to simulate as much as possible in the tissue of the system.Lower respiratory tract [1617] inhale of breath samples to help breathing should be obtained from patients receiving invasive respirator. Lung membranes, for example, the clear liquid and air tube if it is possible they also tested samples should be collected from several.Places to breathe for the consecutive patients with suspicious that the H5N1 bird flu virus infection, blood or feces should be tested for the diagnosis, monitoring of H 5 N 1 Virus RNA in these examples demonstrate a poor prognosis [37] diagnostic testing methods.In order to confirm the H5N1 virus infection is acute examination of virus RNA in respiratory samples from the polymer chain reaction-reverse transcription (RT-PCR) [40, 41] (table 1)) and real-time RT-PCR Assembly. Can be carried out under a biological safety level 2 standard protocol conditions and chemical detection of H5N1 virus, [40] and realtime H5 RT-PCR phrai and investigation platform (developed by CDC) are stored for distribution [42] laboratory problems and are as follows: appropriate RNA extraction using?In order to improve the primers and fuses (because of the H5N1 strains have developed) using the appropriate control and increase the efficiency of testing RT-PCR [43] virus isolation should be carried out under a biological safety level 3 increasing machine, which can be performed at the World Health Organization laboratory 5 H.Reference [41, 44, 45] RNA viruses ' from g-series Dino specimen from H5N1 strains from expanded or RNA that are important in the evaluation of genetic reassortment and mutation detection, which may affect the transmission of the virus or worm-style resistance of the virus is essential for.For monitoring the evolution of the virus strain H 5 N 1 and for vaccine development. Commercially available rapid diagnosis and sensitivity are not specific for detecting H5N1 virus infection and is not recommended [40, 46] immune tests can diagnose the H5N1 bird flu virus infection backwards and can confirm the results test RT-PCR by the immune.Microneutralization test [40, 41, 47], which requires of the H5N1 bird flu virus, live monitoring neutralizing. Antibody and biological safety level 3 increasing restrictions of data shows that H5N1-neutralizing antibody was detected in serum samples 10-16 days from the onset of illness [48] collected a pairing of acute (gained within 1 week, etc.Ngachak at the onset of illness), and recuperate (2-3 weeks given later) the serum sample is necessary antibody titer H5N1 positive. Serum samples may recuperate the historical diagnosis of H5N1 virus infection with clinical illness compatible but is unable to determine the duration of the infection that has been published on the criteria for infection [41] horse edit cell hemagglutinin-inhibition test of red blood cell [49] microneutralization test results can be confirmed [38] But this horse red blood cell test fix hemagglutinin-inhibition, as well as other.To test the immune be verified per.
