At present, the international HIV-1 detection of new infections There are many ways, but most methods is complex and expensive. Yunnan Provincial Center for Disease Control and Prevention by Li Hong, who pioneered micro-gelatin particle agglutination HIV-1 infection in the recent detection methods (PA-LS) is a simple, inexpensive and easy to promote HIV-testing new methods. "In this way the cost of testing a sample of only a dollar." Li Hong said.

Innovation

The new method to determine time of infection

According to Li Hong, at present the international HIV detection method commonly used in the main test measured whether HIV infection, and can not detect HIV infection how long. "But this method can detect which are infected with HIV-1 recently and which are long-term infection."

"Screening for HIV antibody positive, after WB (HIV infection to confirm methods) identified as HIV infected, with the PA-LS method can determine who is infected with HIV within six months, or six months before the infected with. "Li Hong said, AIDS is an infectious disease, in a certain time, a certain population for HIV testing, if a clearer distinction between what is a long-term infection, which is a recent infection, we can calculate the population of new HIV hair infection rates.

"Calculate the emerging infections, can help control the spread of AIDS epidemic trends, prevalence and trends of changes in the speed of assessment and evaluation of AIDS prevention and control measures put into effect there is a very important role." He said.

Cost

Testing of a sample of only one dollar

According to Li Hong introduction, PA-LS is a gelatin particle agglutination method (PA) based on the established. PA is the world's recognized as a simple, convenient method of detection and diagnosis of HIV infection, the price is also more expensive.

After the study found that the PA method improved cost savings over the past few times the case can still maintain a relatively high sensitivity and specificity. "Task Force through R & D, the detection of HIV infection in a sample of the PA reagent improved, thirty or forty can be used to detect recent HIV-1 infection in a sample, thus greatly reducing costs." Li Hong said that the current international there are more than 20 kinds of detection of recent HIV-1 infection was used to determine the cost of a sample of about 40-200 yuan range, "but the PA-LS cost only a dollar."

Operation

No instrument can determine the naked eye

"As long as a half-day training, HIV screening laboratory staff would do it." Li Hong said that the current methods used by the international community are complex, micro-gelatin particle agglutination (PA-LS) then "do not need equipment, results can distinguish with the naked eye and is very easy to spread. "

Li Hong further information, although the R & D test has passed, but if you want to be widely used, but also the need for more field research, particularly with the internationally recognized some of the methods of comparative study. "It is envisaged the outcome of next year, hoping Yunnan and other provinces and cities can be employed widely." (Young's high quality and high fluttering intern)
