How Accurate Is The HIV Test 28 Days After Risk?
Hello, I want to ask if this article is correct “Day 28: 95% of cases, antibodies can be detected accurately through testing (HIV testing) Day 90: 99.7% of cases, antibodies can be detected accurately. ” 1. Are there 28 patients with HIV non-reactive tests, then 90 days of testing become reactive? 2. Tests in private laboratories such as Prodia and Farma chemistry usually use what generation and what method? 3. Do I need a test today, which is the 28th day after a risk? 4. Is it true that the window period is up to 6 months or 1 year? I am very worried. Thank you
Good evening, thanks for asking at HealthReplies.com. We understand your concern. To answer that question, it is important to understand that there is a window period. Window period is the period or period in which a disease has actually infected someone, but can not be detected through investigations.
In HIV, the window period is from the 4th to the 12th week, or the first to the third month after risk behavior. Or maybe based on the article you read, on the 30th day to the 90th day. That is why, patients suspected of HIV have to do two HIV tests, namely at the 4th week and the second at the 12th week. This is because if you are declared negative at the 4th week, it will not necessarily be negative at the 12th week. After the 12th week, usually the results will remain in most cases. But if it is positive at week 4, then it will usually be positive at week 12.
Regarding your second question, to avoid misunderstanding, it would be better if you ask directly about the method they use. But because the point that you want to know is its validity or accuracy, with a laboratory that has such a big name, the test they should do is quite accurate.
For further questions, we recommend that you continue to do the test as early as possible, because if it is indeed diagnosed positive now, treatment can be given immediately. That is why even if the test results are used at 12 weeks, you still have to do the tests at 4 weeks.
Finally, as we said earlier, the window period for HIV only exists in the first 1-3 months. Even if there are doctors who ask to have an HIV test after 3 months, for example in the 6th or 9th month, this is usually only in certain cases where the risk is very high, but the results are still negative or less reliable. So it's not routine, and generally enough until the third month.
Apart from that, we realize that you are anxious, many people are like that when they wait for the results of their HIV tests. Even not uncommon, who have twice gotten negative results also remain worried. Therefore, all you need to do now is do the test, and sincerely wait for the results later. Calm yourself, and consult a doctor immediately. So, hopefully answering your question.
