Wow thanks
Thanks a lot I got HIV pcr negative after 15 days of exposure with a sex worker I was worried about the window period but thanks to you I have got clear my mind by anxiety so HIV pcr test is accurate after 12 days thanks a lot.....
Bro I have unprotected sex with a sex worker today and I am very scared
What should I do I need ur guidance
No you need the 30 day test. he just said it takes one month to produce antibodies. I hope you not having sex.
@@thisblackmansperspective4453 yes but if it depends of what kind of Exposure u have like unprotected with men or women
First comment! :) Awesome simple video. Thanks!! :)
How long window peirod for elisa test ?
so is it the p24 or the rna that can be detected first?
for future readers: rna can be tested first. p24 is close though
I have read so many article but kind a still confuse about the date of testing..is negative elisa test at 28th days quite reasurring? Or should i get tested at 30th day...since many article say 1 month...what is 1 month? At 28th day after exposure or at 30th day?
elisa tests can detect antibodies (the immune response) AS EARLY AS four weeks but anything before six weeks is def not conclusive if you had a high risk experience. i'm not sure where you're located but 4th generation tests which look for antibodies and hiv-specific proteins, which can be detected at 30 days.
@@Lil08103 i am located in Jakarta Indonesia. The test I took is 4th Generation elisa test. I tested twice 28th and 36th days. Is. My test result reassuring? Regardless high or low risk exposure, since im not sure about the risk terminology
@@luffy-zd8bw i will answer in two parts: short answer and long answer. the short answer is that your first test at day 28 is reassuring while the one on day 36 probably does not carry any additional significance.
@@luffy-zd8bw long answer: i agree with your original point regarding slightly conflicting info across articles about the ideal date to test. paused at the 4 min mark, this video implies 35 days after potential exposure would be the most ideal date to test. but most sources suggest p24 antigens (hiv specific proteins) have already dropped drastically by day 35 because antibodies have been produced. at the same time, there aren't enough antibodies to be detected by day 35. in my extensive reading, 28-30 days is ideal. immediately after is a long shot until 60 days. if a person has potentially been exposed, my recommendation is to test at day 28, 60 and 90.
Test are bs if u have HIV aids symptoms u have the virus if not u are ok government scam test do research
This is by far the best video I have seen on this subject, clearly presented, easy to understand and very informative. Helped me a lot to understand my testing options. Thank you 👍🏽
Quick question, after HIV exposure If a course of PEP had been started within 72 hours. Would the HIV test be accurate at day 10 and 28, or would the PEP have suppressed the HIV virus and produce a false negative positive reading ?
Tested non-reactive at 26 days should I re-test? Using a test that detects p24
Is there chance of false negative result after non reactive using CMIA in week 5 then rapid antibody week 13. Both test are non reactive. Now iam verry worry
did u test again??
Moved on dude your negative
How u confirm that a donor blood has not HiV my be he is in the window period?
The test used by Blood banks are even more sensitive then the regular tests so there is a chance it can give false positive but there is no chance it will give false negative, further more there are no known cases where hiv has happend through blood transfusion in modern medical faculties.
Can anyone answers this question??
Does the different Hiv Strains ( the Types or Subtypes) have an impact on the result of the test?
An Antibody test for Hiv1 type M Subtype B or Non B can as well well detect Hiv1 type O or N ?!?
Is Hiv Antibody Cross Reactive?
I have heard that some type of Hiv like Type O and N can't b detected by the conventional antibody test , is it true?
yes, for example western blot is only for HIV1 antibodies, while the rest are for both
can u tell me how you draw these and upload on UA-cam ??plz

Sir reactv or non reactv ka kya matleb hai hiv may
Hi
How about cmia sir
so, do you mean that after taking a lab 4th generation ag/ab duo is conclusive at 4 weeks ?
william encarnation it’s conclusive at 28 days or more but you should still get a confirmatory test at 3 months. It’s just protocol because 5% of people take another 2 months (after the original 4 weeks post exposure) for antibodies to show up. Hope this helps
@@thehangoutpodcast2263 3 months or 12 weeks? I am gonna become paranoid
I tested negative at 3 months with antibody test is it conclusive ?
@@helloagain1400 yes move on
@@joshua50101 3 months is 12 weeks lol
I've had 2 blood transfusions (2 pints both the first and second time for a total of 4 pints). I was told that I needed to be tested for HIV and I was so scared.While awaiting those results,i was a bundle of nerves because I heard that one of the ways that HIV is commonly transmitted is via blood transfusions.I was first tested in 1995 and then some years later in 2014 I believe. I was given those transfusions in 1993. Fortunately I tested negative for HIV both times. I was so relieved when I was told my results for HIV were negative. How many times does someone who has has blood transfusions need to be tested,even if those transfusions were given years ago?
Carla Head lol. Did you watch the video?
+Thomas Cogger - I'm sorry but I missed what was supposed to be so funny about her question?
@@MakeWay4CJ Its funny because she asks this elaborate and specific question but clearly did not watch the video, because the video has all the answers to what she asked
I say don't worry about a dn thing.
Tests are also NON SPECIFIC
I wonder what is the accuracy of the 4th gen test after 4 weeks, it seems to be around 85%? and yes I know the gold standard is to wait 45 days after the last exposition to have a 99.9% accurate result
thank you Lord for giving Dr Jibola the wisdom to fine the cure for Hepatitis B
I’m an engineering student and I’m pretty good at it but I don’t know how medical students memorize all this stuff
Is immunoassay test is ELISA.I got tested and says non reactive reagents for hiv 1 and hiv 2.what does it mean.
A non-reactive result should be intepreted as that there is no labratory evidence of an HIV infection.
@@richardma9691 so am i Hiv negative.it means
san sat that depends on how much time have passed since your previous possible exposure to HIV. If your test was conducted outside of the window period then yes you are HIV-. If not then get retested after the window period. Always consult your healthcare provider before making any decisions about your sexual health. Good luck my friend.
@@richardma9691 bro i did test recently and result said non reactive
Exposure in 2018
san sat oh then if there is not another potential exposure between then and when you got tested you should be confident that your status is HIV-. This is not a medical advice and again you should always consult your healthcare provider regarding decisions about your health. Good luck and be well.
You gotta give it to the current "dating" market that a lot of these diseases are being thwarted.
As of 2018, a 4th Generation HIV 1 & 2 duo/combo Anitibidy test (has a 95% accuracy in 30 days after possible exposure) along with a HIV 1 RNA QL TMA (99% accuracy after 30 days). Both test will be a blood draw taken to a laboratory for processing (not a rapid test). The 4th generation HIV 1/2 Antibody is far better than the 3rd generation. Along with the 4th generation an HIV1 RNA QL TMA (early detection test) will be given just to be conclusive. The HIV1 RNA looks for the actual HIV DNA in your system and has pretty much replaced the Western Blot.
Mr. M A J E S T I C XIII . Blackstruggle77 that’s what’s advertised, 90% proven to be wrong lol this is a joke
How about roche cobas taqman hiv-1 rna test (quantitative) limit 32 copies.
Is it reliable 30 days post possible exposure?
If u got symptoms of HIV and aids u got virus if not Don't worry about it or test will give u the virus
@@kingkato2731 what's wrong with you dude? You are saying totally the opposite of what's really the case with hiv infection, please go throw your crappy inf somewhere else.
Is the finger prick blood test for HIV reasonably accurate ?
Yup .. take 3 rapid finger prick tests. If all 3 come back positive, you'll need to get Elisa or NAT test to figure out just how sick you really are. This is because you have HIV that might actually be AIDs !
Is RNA test accurate 88 days after exposure ?
yes its considered highly accurate after 11 days
I got the hiv result test is non reactive only by 90 minutes with combe Elisa method.. after 91 days ..is it valid ? Cuz you said elisa takes few days or a week to get the result ?
Was my doctor did the mistake ?
Same condition aapne dobara karwaya kya
Tested hiv1 rna qualitative pcr got negative after 30days... am I safe or not
same i have done this after 2 months safe or not ? bro what is ur status
The NAT is RT-PCR?
Yes
Do you know the difference between the NAAT test and the viral load test?
Hi
Can Hiv, Aids virus died very quickly in air and water ?
I tested negative 3 months after I had unprotected sex. I retested 3 months after and still negative. Am I in the clear now?
Willy Rodas you are in the clear as long as you haven't had any other encounters since then to put you at risk. Dirty needles, unprotected sex, breast milk feedings, en utero, or during birth process are basically the main ways people become infected.
Willy Rodas ur negative be careful not be infected
Negative doesn't mean shit if u have a lot of HIV aids symptoms u have it if not u are fine test not accurate
@@kingkato2731 based on your experience right😆
@@kingkato2731 i know you are hiv positif
What if I punched my cousin on the mouth and never got tested until 2017 would it test negative?
It really amazing to hear good news from Africa herbal doctors these days,I truly appreciate #doctorogie for his help and getting some of his herbal medications though it's affordable and very effective as promised,I truly say thank you for your help and assurance of my health I'm so happy💯💯💯
4 weeks after exposure get a HIV blood test, but 2 weeks before get a Chlamydia/Ghonorrhea urine test.
Meeting #DrKanayo Peterson on UA-cam is like meeting GOD himself because what you did in my life is what
no doctor can’t do. Thank you for curing my hiv totally😁♥️
I had a negative ELISA on day 35 after exposure and was advised to repeat after 1 month. But I still have swollen and painful lymph nodes. What would you advise me to do next? All this happened after high risk exposure through unprotected sex.
Andrew OKUNI then you should repeat a test. 28days of elisa, should be conclusive. But, to rule out, you should have retest. All the best.
Please stop googling and looking for the symptoms. Sometime, stress also can cause swollen lymph nodes.
@@adamf4950 thanks
Raj Jairu hi raj did u get tested again? I had unprotected oral sex in which I was the receptive. After two weeks I begin to have pain in my groin area and in armpit. It’s now the 30 day. I tested after 2 weeks but it was negative. Should I go and test after 35 days?
@@adamf4950 , thank you. The anxiety associated with high risk exposure is unmatched. I repeated the test after 1 month, still negative. I also had a sample taken off for PCR at day 55 post exposure and the result was negative. I agree with you about the stress being a possible cause of swollen lymph nodes, repeated flu-like bouts and general unwellness.
andrew okuni that’s true buddy, anxiety can cause swollen lympnodes in groin, armpit and neck. I had oral sex I tested after 2 weeks it was negative then after 50 days it was negative now I have to wait almost 90 days to test again. But hiv antigen/ antibody hiv1/2 can detect 96% virus after 4 weeks but I would wait for 3 months to pass to be sure.
If u don't have sex or any sexual contact or breast feed... can u still get it?
if you share needles with hiv infected people . Or press your wounds on other hiv infected people for whatever reason for a certain amount of time
Your video was amazing, thank you very much for the info. One question, the NAT can give you a diagnostic? ~LUCKYLOBO
It's shit
A negative result in 143rd (5th month from exposure) day in ECLIA HIV 1 and 2 test is conclusive? Or anyother test is needed for confirmation?
conclusive no further testing required .
@@BlinkGill sir i had sex 3 years ago and i didnot test my hiv at that time now its 2020 and i tested yesterday and it came negative but i heard from. Someome that you find your hiv accurate if you test within 6 months if you test after 6 monthss as i tested after 3 years you test can't detect hiv after 3 years. So sir u tell is it right or i am safe and i tested hiv 1 2 rapid test
@@ManveerSingh-xe5sy your safe don't worry your negative
@@ManveerSingh-xe5sy hiii bro
Hi kevin
So after 1 month of risk, when you got your Combo test negative which includes P24, that means you're not infected?
Dandi lf no you need a PCR-RNA test it is the only definitive answer. But it’s not cheap so they probably won’t offer it.
Yesv
Both tests are non specific. Proteins are all non specific.
1986 + 1991 tested positive
2019 tested negative. 27 years of ARVs.
wow...does this means u r cured from hiv?
@@UnKnown-rz9hn no
Probably never had it
This isn't a real conversation. This dude is just playing games.
You'd never test negative if you really had HIV. (That's true)
You would never test positive twice in a row if you didn't have HIV !
You got what's called a "false negative" and need to test again if this is actually a truthful conversation.
My greatest gratitude goes out to #Drkanayo Peterson, I’m glad
my husband was able to
get rid of the hepatitis B and HIV Aids virus with your 14 days negative.
Meeting #DrKanayo Peterson on UA-cam is like meeting GOD himself because what you did in my life is what

What is the window period for HIV DNA PCR TEST ??
I Took if between 10 - 12 days of exposure.
Is it valid ??
take antigen/antibody test, 3 months would be conclusive. pcr is expensive and prone to false positive
