HIV I II GenScreen Biorad ELISA method - Question

[orionorion]

Hi there,

I had a gone to take my final test today at the clinic in Trinidad and Tobago.

This is my 12/13 week test. I have not recived the results as yet as they said it will take 2 days to prepare.

I had taken my last test on the 8 week mark and it came back negative.

I asked the lady who was doing the test to give me some information on the type of test that was being issued.  She read the following of  the HIV box "HIV I II GenScreen Biorad ELISA method"

Does anyone know how good this test is and if it realiable and does the 6wk - 8wk still hold for this type of test?

Thanks.

It does indeed. At three months, test generation is irrelevant. Your results won't change.
What was your risk?:)

I perfored oral on a girl of unknown status with a blister on my lip.

I just wanted to know what generation the ELSIA test i quoted above is.

It is not clear what is the standard in terms on generation is in different parts of the world.

The doc stated that in a forum of 300 experts not one person had seen someone turn positive after 8 wks and they were negative before.

However, the statement did not say what generation of tests they used and what type.

I know its two days to wait for the test.. but two days mate feels like a lifetime sometimes yes.

My friend, you wasted your money and your time. I will state here with great authority that you did not have a risk. I am certain that your test result, even if the test was 20 years old, first generation, will be accurately negative.

Congrats:)

Yeah I know.  But you see the person you may have performed on could have been negative.. mines could be different. I know you trying to be supportive .. much thanks.

But am looking for facts.. facts on generation and if the person was positive.

No offennce.. all help and support is greatly appreciated.

It doesn't matter if they were positive or not. It really doesn't because you didn't have a risk.

But since you asked....

Genscreen Biorad is a 4th generation ELISA, and is therefore one of the most up to date HIV tests on the market. You couldn't have had a better one.

If your lady friend was positive and had infected you - an impossibility based on your risk - your test would have been over 99% accurate at 6 weeks. Therefore you're home dry.

Honestly:)

Thanks,

That makes me feel better, much better. Where can I get the information on the generation by the way?

What websites do you use for the research.

Hey I never asked (not like it matters lol ) are you a guy or a girl? Just asking..

Its so hard to find info on generation type and type of test.

[dobber21]

I'm a guy...or if not, a girl who has really let herself go!

Now stop reading and let this go!:)

i asked this question a few weeks about the different type of tests...is MEIA the same as ELISA?  someone replied that, yes, they are the same thing.  After reading the article from http://www.hivmedicine.com/textbook/testing.htm
i am led to believe that they are not the same.  I tested neg at 50 days using a "HIV 1/2 Screen MEIA Test".  Does anyone know the difference b/w the standard ELISA test and the MEIA one i had?  

thanks guys, i look forward to your responses.

Thought I'd let you have a look at this table that is posted on the San Francisco City Clinic (STD clinic).

http://www.dph.sf.ca.us/sfcityclinic/stdbasics/stdchart.asp

It categorically states - giving a BJ = possible, very low risk
any other type of oral sex, risk = NONE.

SF is the city with the third highest number of HIV+ people in the US. If they're putting that on their website, it's pretty believable.

Hope that helps quell any anxieties...

Hi going crazyy. The MEIA and ELISA are basically the same in principle, they just use different "solid surfaces" to which they bind HIV-specific proteins, which the Abs in blood or oral material then binds. The ELISA uses the bottom of a plastic plate to coat, while the MEIA uses tiny particles (microparticles) in suspension.

Basically, they detect the same thing (Abs) with the same sensitivity - 1 just uses a flat surface while the other uses the surface of small spheres. I'd draw you a diagram if I could as it would make it easier to understand.... :)

thanks for the info, and no, you don't need to draw a diagram, i think i get it.  Thanks again.
