Go to CDC four weeks after high risk

1. It is generally required after 6 weeks. If the test is negative after 6 weeks, 99% will not turn positive after 6 weeks.

2. Generally speaking, the window period for HIV detection after high-risk behaviors is three months. Accurate results can be obtained only after three months. Before you go to the CDC, you can test yourself at home through saliva. Tianmao can buy related procts. The most expensive but most accurate one on the market is Aiwei. After preliminary testing, if you have any questions or are positive, You can go to CDC for examination.

3. Hello, the window period of AIDS is generally 2 weeks - 3 months, so after high-risk 6 weeks can go to test antibody, negative words, the possibility of infection is not big, 3 months and then test negative words, you can rule out the possibility of infection. AIDS is an incurable disease, so we must keep clean. Or you'll ruin your life.

4. Three months! In the future, we should keep clean

5. Aids can be transmitted through sex, blood and mother to child transmission. If your sexual partner finds out AIDS, you should be alert. The high-risk patients can go to the hospital for examination after one month. If they are negative, more than 90% of them can be ruled out. However, after three months and half a year, they still have to go to the hospital for another examination.

6. Generally, the detection is negative after 4 weeks, and the possibility of turning positive after 4 weeks is very low. Don't worry too much, and the problem is not big. The 4-week exclusion rate was more than 84%
it is recommended to review 6 weeks and 3 months later

7. In the second week and the fourth week after the occurrence of high-risk sexual behavior, you should have a check-up. If you have no problem twice, that means you have no problem for a month, it should not be a big problem. And when you go to the check-up for the first time, the CDC will tell you how to check it. Good luck< The accuracy of 1-2 weeks was 75% - 85%

4 weeks was 97.5% - 99.6% (30 days was 98% - 99.5%)

5 weeks was 99.8% - 99.95%

6 weeks was 99.95% - 99.999%

8 weeks was 99.99999%, which could be completely excluded

8. General high risk 2 to 4 weeks can be detected! If your test is negative in 4 / 6 weeks, you are now healthy. Don't worry! When HIV enters the human body, it takes a period of time for the blood to proce HIV antibody, ring which the antibody test is negative, which is the window period. The number of HIV in infected people will reach a peak at this time, which is highly infectious, and the acute infection period also appears ring this period. At present, the international and domestic consensus is three months. Different routes of infection may infect different subtypes, but they can be detected in the antibody test after the empty window period. At the same time, the number of HIV entering the body will not affect the length of the window period. That is to say, whether it is blood transfusion infection, sexual intercourse infection, breast-feeding infection or other forms of infection, and no matter how much HIV is infected, antibody positive reaction will generally appear after the window period. In addition, on the one hand, the current saliva test paper technology is sensitive enough, even more than the domestic blood test paper. For example, the international brand aware has also landed on TM & JD; On the other hand, we are all healthy young people. Can't we proce antibodies after such a powerful virus for a year? Of course, as far as I know, all people will go to review when they are three months old. It's necessary to add a 100% assurance insurance to their health and give them 100 confidence! I hope my answer can help you, thank you!

9. This is the use of rapid detection reagent, a few minutes out of the results are normal, the results are credible, negative ruled out the possibility of infection.

10. Yes, thermoelectric power generation, Seebeck effect. But the technology for power generation is not mature, now only used for temperature measurement, that is thermocouple< In 1821, Seebeck, a German, discovered that in a circuit composed of two different metals (antimony and copper), if there is a temperature difference between the two joints, there will be a magnetic field around them, and through further experiments, it is found that there is an electromotive force in the circuit. The discovery of this effect lays a foundation for the fabrication of thermoelectric thermocouples, thermoelectric generators and thermoelectric sensors

thermoelectric conversion materials directly convert heat energy into electric energy, which is an all solid-state energy conversion mode without chemical reaction or fluid medium. Therefore, in the process of power generation, it has the advantages of no noise, no wear, no medium leakage, small volume, light weight, convenient movement, long service life and so on Microelectronics and other special applications have an irreplaceable position. In the 21st century, with the deterioration of the global environment and energy conditions, and the difficulty of fuel cells in practical application, thermoelectric technology has become an attractive research direction

the working principle of thermoelectric power generation: when one end of two different types of thermoelectric conversion materials N and P is combined and placed in a high temperature state, and the other end is opened and given a low temperature, e to the strong thermal excitation effect at the high temperature end, the concentration of holes and electrons is also higher than that at the low temperature end. Driven by this carrier concentration gradient, holes and electrons diffuse to the low temperature end, Thus, a potential difference is formed at the low temperature open end; If many pairs of p-type and n-type thermoelectric conversion materials are connected to form a mole, enough high voltage can be obtained to form a thermoelectric generator.
