Urgent! Will there be a fake yang when checking HIV? My girlfriends were scared and cried

There is a fake!! The virus cannot be detected in ordinary hospitals!! You need a special check-up!!

Do you know!! And if it's true, this has nothing to do with your current sexual behavior, blood transfusions, blood donations, etc. can be caused! In addition, this incubation period is very long, up to ...... yearsThis is a disease of wealth, and the general population cannot get .........If you don't worry, you go to another hospital for a physical examination, don't say anything, just say that it will be checked**, and say that you will have a routine physical examination every year???

Do you understand, if you want to talk nonsense, it will definitely find out the relevant virus for you, why?? You know!!

In addition, according to the symptoms you said, your girlfriend should be congenital kidney element deficiency, so after sharing a bed with you, Guan Yuan suffered from the cold .........That is, the lower abdomen .........

The internal symptoms are that the spleen and stomach are weak, and the lung qi is not reached, which cannot help the kidney yang .........You use 200 grams of yam (Chinese medicine store, powdered) 10 grams of psyllium, boil carefully, add water seven times, that is, add some cold water, so seven times, make the porridge very white, thick, just take it!! It should stop ......... after two hours

Hello, according to your description, there is a real possibility of false positive results in HIV testing, and the specific diagnosis is generally not in a tertiary general hospital.

Further confirmatory testing at the infectious hospital in the place is recommended. I wish you good health.

Hello! Figuratively speaking, the sensitivity of the test will be strengthened during the initial screening test, so that there will be no fish that slip through the net. Sometimes the virus is mistaken for HIV, so there will be false positive results.

In principle, if an authoritative institution (such as a tertiary hospital or the CDC) gives a false positive result, it is a false positive result, and the false is false, and it will not become true for a long time. You are just excluded and not infected with HIV.

If you're still not sure, there's another way. If you continue to test until the test result is still negative 6 months after the high risk, you can rest assured. If you don't want to go to the hospital or CDC all the time, then I suggest you buy some HIV saliva test kits.

It seems that you can find it on Jing Dong or Sky cat, and there are many brands, such as aware (Aiwei), Youlian ......Especially when summer comes, it is necessary to pay attention to whether there is cold chain transportation, and the detection reagent will be inactivated at high temperatures. Choose according to your needs.

The probability of a false positive depends on the time of the test.

The probability of a false positive is very, very high when tested within three weeks of a high-risk infection.

At the current level of testing, the window period for HIV is generally set at six weeks, and the detection accuracy rate is after six weeks.

It is recommended to go to the ** department of a local tertiary hospital or the CDC for paid or free HIV screening 6 weeks to 3 months after high risk, which is basically accurate for 6 weeks and completely accurate for 3 months.

What is a false positive?

When a person who is not infected with HIV tests positive, the result is considered a false positive. In general, HIV tests have a high degree of specificity (precision), but false positives can still occur, and the vast majority of people who are not infected with HIV test negative.

Causes of false-positive HIV test results.

False-positive test results may be due to technical or biological reasons.

Technical issues include sample mix-ups, mislabeling, mishandling, and misinterpretation of rapid test results (which rarely happens).

Biological causes include interference with the use of certain medications, autoimmune system responses, and the effects of other diseases.

The impact of the AIDS epidemic on false positives.

HIV prevalence refers to the proportion of people living with HIV in the population.

The prevalence of HIV in the population being tested affects the proportion of false positives in the proportion of positive results from the first test.

High prevalence areas: If you test 10,000 samples with a high HIV infection rate (2%), 200 of which are true positives, 9,800 samples are for people who are not HIV-infected. If the specificity of the test is high, about 20 results may be false positives.

In this case, there may end up with 220 positive results (200 true positives, 20 false positives). Of these, 91% are actually infected with HIV. The number of true positives far exceeds the number of false positives.

Low prevalence areas: If the prevalence of HIV is low (, then only 10 out of 10,000 samples are from people who are actually infected with HIV (true positives) and 9,990 are from people who are not infected with HIV. If the specificity of the test is high, there will be 20 possible false positives.

In this case, only 33% of the final 30 positive results (10 true positives plus 20 false positives) are infected, and the number of false positives will exceed the number of true positives.

In China, there are about 700,000 people living with HIV, accounting for about the total population, and in this case, the number of false positives will be much higher because of the above reasons.

What is Specificity?

If 1000 uninfected people are tested for HIV and 4 of them are false-positive, then the specificity of the HIV test is a true negative result (1000 uninfected people).

How to identify false positives.

When a screening test is positive, additional testing is generally needed to determine whether a positive result is accurate or if a screening test result is falsely positive. In the case of laboratory tests (blood tests drawn from hospitals and other institutions), additional tests are usually performed using the original sample.

In the case of a rapid dipstick test, a blood test can be done by going to the nearest hospital to determine whether there is an infection or to rule out false positives. However, if subsequent tests are negative, a NAT test may be done, or a return visit to the hospital or CDC for a blood test (laboratory test) may be done at a later date (usually 4 to 6 weeks) to rule out early infection.

If a single test is positive, don't be discouraged, it's likely to be a false positive.

1. When using the AIDS test strip test, other substances entered, and the wrong result appeared, and there was a false positive.

2. Adding too much blood or buffer makes the AIDS test strip too wet, and a red mark formed in the detection area looks like a false positive.

3. Premature detection, the amount of HIV antibody is too small, and a weak positive (false positive) appears, which is more dangerous.

4. There are other diseases, and the cross-reaction is a false positive.

5. Long-term use of some drugs has changed some substances in the human body, and false positives appear when tested with AIDS test strips, and can return to normal after re-examination about a month after stopping the drug.

6. The probability of false positive in the detection of products is very low, and strict and detailed tests have been done before leaving the factory.

In the above situation, do not panic, it is impossible for any kind of test to be 100% accurate, and there may be incorrect results in hospitals and CDC tests, so there will usually be "pending re-examination" and repeated testing. So don't worry if you have a false positive, you can repeat the test, and you can rest assured.

For the questions you asked.

Since the purpose of the primary screening reagent is to test all positives. Therefore, the reagent should be as sensitive as possible, and even if it is possible to test a healthy person positive, it cannot miss a real patient. Therefore, it is better to mistakenly screen healthy people as suspected of HIV infection.

There are many factors that go into a false positive. For example, people with blood malignancies, autoimmune diseases, multiple biliary cirrhosis, alcoholic hepatitis, multiple myeloma, kidney transplantation or chronic renal failure, malaria or filariasis, or vaccinated (influenza, hepatitis B) are prone to false-positive results.

I believe you already understand that the false yang is because the reagent is too sensitive, and healthy people are mistakenly shown as positive. i.e. a false yang.

A positive initial screening does not necessarily mean AIDS, but a high suspicion of AIDS. You must have been diagnosed with HIV by the Center for Disease Control and Prevention.

Hello, not all symptoms will appear, some are only one or two, and some may have six or seven, and the symptoms are very different depending on the individual's constitution, so the symptoms do not represent the standard of being infected with AIDS. If you are infected, it usually takes 2-12 weeks, an average of about 45 days, for HIV antibodies to be detected in the blood. The period of time between infection and the production of antibodies by the body is not detectable for HIV antibodies, which is called the window period.

Although HIV antibodies are not detectable during the window period, if they are infected, they still have the HIV virus in their bodies and are also infectious. To put it simply, it will not be detected if it is done too early, and it can be ruled out after 6 weeks with a negative test. Don't forget.

One out of 100 healthy people is found to be an HIV carrier or positive for HIV antibodies, which is what 1% false positive.

If you really don't feel at ease, get a public welfare test strip and the test will not be over. It's not so scary now.

Antibody tests for all viruses show false positives.

There is no probability of being negative!

If there is, there is, and if there is none, there is none.

There will only be a false yang, and there will be no false yin.

It can be ruled out as long as you test negative within the specified time frame.

What causes false positives in HIV primary screening tests?

1. Blood malignant lesions.

2. Autoimmune reactions.

3. Primary biliary sweat cirrhosis.

5. Vaccination (influenza, hepatitis B).

6. Multiple myeloma.

7. Kidney transplantation or chronic renal failure.

8. Malaria or filariasis.

9. The amount of antibodies in the human body is too low, so it should be rechecked.

10. The problem of the use of test strips should be re-tested.

What causes false negatives in HIV primary screening tests?

1. HIV window period.

2. Immunotransplantation.
