Arkadaslar smdi rna pcr’da sadece negatif yazmasıyla ilgili test oldugum labı aradım doktor negatif yazması birtane virüs bile bulunmadığını gösterir dedi söz konusu dahi olamaz dedi bir virüs dahi olsa saptanamadı ve negatif yazması aynı seydir dedi testi yapan yerin doktoru şafak göktaş 2 pcr testimin altında lineer aralığı 60-50.000.000kopya mldir diyor minimum saptama limiti 33.45kopya mldir diyor 1u/ml 0,5 kopyaya denk gelmektedir diyor bu test artus Qiagen hı virüs 1 rg rt pcr kiti ile çalışılmıştır diyor yani 0,01 virüs bile çıksa negatif yazarmıydı sizce
Arkadaslar gelisimde pcr olupta negatif alan kimse varmı varsa eger negatifin yanında sonuç kısmında saptanamadı ibaresi yazan varmı sonucunda ? Sadece negatifmi yazıyor yanındasaptanamadı yazan kimse varmı ?
No HIV test can detect HIV immediately after infection. If you think you’ve been exposed to HIV in the last 72 hours, talk to your health care provider about post-exposure prophylaxis (PEP), right away.
The time between when a person may have been exposed to HIV and when a test can tell for sure whether they have HIV is called the window period. The window period varies from person to person and depends on the type of test used to detect HIV.
A nucleic acid test (NAT) can usually tell you if you are infected with HIV 10 to 33 days after an exposure.
An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure. Antigen/ antibody tests done with blood from a finger prick can take longer to detect HIV (18 to 90 days after an exposure). When the goal is to tell for sure that a person does not have HIV, an antigen/antibody test performed by a laboratory on blood from a vein is preferred.
Antibody tests can usually take 23 to 90 days to reliably detect HIV infection. Most rapid tests and home tests are antibody tests. In general, antibody tests that use blood from a vein can detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid.
Ask your health care provider about the window period for the test you’re taking. If you’re using a home test, you can get that information from the materials included in the test’s package. If you get an HIV test after a potential HIV exposure and the result is negative, get tested again after the window period for the test you’re taking to be sure. If your health care provider uses an antigen/antibody test performed by a laboratory on blood from a vein you should get tested again 45 days after your most recent exposure. For other tests, you should test again at least 90 days after your most recent exposure to tell for sure if you have HIV.
If you learned you were HIV-negative the last time you were tested, you can only be sure you’re still negative if you haven’t had a potential HIV exposure since your last test. If you’re sexually active, continue to take actions to prevent HIV, like using condoms the right way every time you have sex and taking medicines to prevent HIV if you’re at high risk.

If you take a test in a health care setting, when it’s time to take the test, a health care provider will take your sample (blood or oral fluid), and you may be able to wait for the results if it’s a rapid HIV test. If the test comes back negative, and you haven’t had an exposure for 3 months, you can be confident you’re not infected with HIV.
If your HIV test result is positive, you may need to get a follow-up test to be sure you have HIV.
Your health care provider or counselor may talk with you about your risk factors, answer questions about your general health, and discuss next steps with you, especially if your result is positive.

There are three types of tests available: nucleic acid tests (NAT), antigen/antibody tests, and antibody tests. HIV tests are typically performed on blood or oral fluid.
A NAT looks for the actual virus in the blood. The test can give either a positive/negative result or an amount of virus present in the blood (known as an HIV viral load test). This test is very expensive and not routinely used for screening individuals unless they recently had a high-risk exposure or a possible exposure and they have early symptoms of HIV infection. Nucleic acid testing is usually considered accurate during the early stages of infection. However, it is best to get an antibody or antigen/antibody test at the same time to help the health care provider understand what a negative NAT means. Taking pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP) may also reduce the accuracy of NAT if you have HIV.
An antigen/antibody test looks for both HIV antibodies and antigens. Antibodies are produced by your immune system when you’re exposed to bacteria or viruses like HIV. Antigens are foreign substances that cause your immune system to activate. If you’re infected with HIV, an antigen called p24 is produced even before antibodies develop. Antigen/antibody tests are recommended for testing done in labs and are now common in the United States. There is also a rapid antigen/antibody test available.
Most rapid tests and home tests are antibody tests. HIV antibody tests look for antibodies to HIV in your blood or oral fluid. In general, antibody tests that use blood from a vein can detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid.
While most laboratories are now using antigen/antibody tests, laboratory-based antibody screening tests are still available. These tests require blood to be drawn from your vein into a tube and then that blood is sent to a laboratory for testing. The results may take several days to be available.
With a rapid antibody screening test, results are ready in 30 minutes or less. These tests are used in clinical and nonclinical settings, usually with blood from a finger prick or with oral fluid.
The oral fluid antibody self-test provides fast results. You have to swab your own mouth to collect an oral fluid sample and use a kit to test it. Results are available in 20 minutes. The manufacturer provides confidential counseling and referral to follow-up testing sites. These tests are available for purchase in stores and online. They may be used at home, or they may be used for testing in some community and clinic testing programs.
The home collection kit involves pricking your finger to collect a blood sample, sending the sample by mail to a licensed laboratory, and then calling in for results as early as the next business day. This antibody test is anonymous. The manufacturer provides confidential counseling and referral to treatment.
If you use any type of antibody test and have a positive result, you will need to take a follow-up test to confirm your results. If your first test is a rapid home test and it’s positive, you will be sent to a health care provider to get follow-up testing. If your first test is done in a testing lab and it’s positive, the lab will conduct the follow-up testing, usually on the same blood sample as the first test.
Talk to your health care provider to see what type of HIV test is right for you.
After you get tested, it’s important for you to find out the result of your test so that you can talk to your health care provider about treatment options if you’re HIV-positive. If you’re HIV-negative, continue to take actions to prevent HIV, like using condoms the right way every time you have sex and taking medicines to prevent HIV if you’re at high risk.

How soon after an exposure to HIV can an HIV test detect if I am infected?

Arkadaslar suan özelden görüştüğüm bu siteden eski arkadaslardan birkaçı wodoo ile ilgili baya bilgiler verdi bana kesinlikle o adamın peşine gitmeyin uçuruma sürükler insanı diyorlar eski nicki 3335 bu arkadasın eski tum konusmalarına tek tek bakın arkadaslar bu adamın sundugu tum iddaalar çürütülmüş ve bu adama 90 da pozitifti dedigi kişiye ulaşılmış ve o kişi negatif almıs dogrulamadan ve negatif olarak hayatına devam ediyormuş ve wodoo bunu bile bile bunu paylaşıyor arkadaslar tum sundugu iddaalar çürütülmüş ve burda birkaç kişiye çok ama çok agır küfürler etmiş agıza alınmicak kufurler hepsi eski konusmalarda var tek tek okuyun diyorlar kendiniz görün diyorlar farkederseniz bi var bi yok net cevap alamıyorsunuz bu adam oynuyor arkadaslar eski arkadaslar sakın bu adamın peşine takılmayın yazık olur ordakilere diyor tek dedigi dogru şu diyorlar antikor yanıtı milyonda bi gecikse dahi 4. Nesil testle herzaman dpgru cevabı alırsınız diyor ikisinde birisini bulur ve 90 son gündür diyorlar ltfen herkes okusun aktarsın ve eski konusmalarını takip etsin.
Yes, you should feel pretty good about negative results from a 4th generation, antigen/antibody combo test with a blood sample taken 33 days after your last suspected exposure.
By day 21, an ELISA test like the one you describe would react positive for most infections.
By day 48, it would catch almost all infections.
By day 90, you could consider negative results to be officially conclusive.
What most clinicians would advise right now is that you breathe a sigh of relief and take a second test at or after the 90-day mark to confirm your results.
Two tests are considered to be standard and prudent.
No HIV test is reliable for negative results at only 14 days post-exposure.
The 4th-generation test you refer to would be a combination antigen/antibody assay. Such tests could certainly detect an HIV infection at 14 days, but that's only the beginning of the so-called window period that needs to elapse before negative results are conclusive.
Timing for antigen/antibody tests is generally as follows:
Most infections are detected by 21 days after exposure.
Almost all infections are detected by 48 days after exposure.
Negative results can be taken as conclusive at 90 days after exposure.
The NAAT test that you refer to is a PCR test that looks directly for viral RNA. It's sometimes called a viral load test.
It may very well be that an infected person would have a detectable viral load 14 days after exposure. Many infected people would be expected to have a very high viral load at that point, as a matter of fact.
That isn't always the case, however. Sometimes viral levels remain low for quite a long time, low enough for the PCR test not to detect significant quantities of viral RNA.
Public health authorities advise that viral load tests should not be used to rule out HIV infection.
Antigen/antibody tests can be used to rule out HIV infection, but according to the timeline outlined above.
Combination antigen/antibody tests for HIV are considered to be over 98 percent reliable for negative results at 48 days post exposure.
They are considered conclusive for negative results at 90 days.
The 90-day standard has quite a lot of confidence buffer built into it. So, by 80 days, you could have virtually complete confidence in negative results.
A negative result anytime after about 48 days would be cause for a huge sigh of relief, with prudence dictating a final, follow-up test at 90 days or later to rule out anomaly.
Public health authorities recommend a minimum of two tests in any case, just to rule out the minimal possibility of lab error.
A 4th-generation, combination antigen/antibody ELISA assay is limited in reliability by the amount of antigens and antibodies present in the blood of an infected person.
The subject is complicated, but in general, reliability of negative results increases on a curve as a function of time.
There's actually a small, anomalous bump intitially after exposure as high viral loads can result in high antigen count. That drops off quickly, usually.
After that point, antibody production increases fairly predictably.
At 21 days post exposure, well over half of all infections would be detected.
At 48 days, almost all infections would be detected.
By 90 days, public health authorities advise that negative results can be considered conclusive.
So, at the six week mark, or 42 days, you can have a great deal of confidence in negative results.
Breathe a sigh of relief and have a final test at 90 days or after as confirmation. That would be the advice you'd receive from most experienced HIV clinicians.
