As far as I know, only 2nd and 3rd generation tests are approved by the FDA. 4th generation tests are not used in the US, to my knowledge. A test at 3 months is reliable for any generation.
I just did and guess what - nothing came up.
The list that I posted includes tests approved as late as 2007, so I wouldn't call it outdated. I think you are wrong.
That is correct - duo and combi are 4th gen., along with the one Teak mentioned and a few others. None of them is FDA-approved though (as far as I know) and therefore none should be used in the US
Like normal Joey you don't know that much. Do you get the Federal Registrar? If you work for a lab, I'm sure that subscribe to the Federal Registrar. You might look at it for the new approvals.
I'm in an academic lab. So we don't do commercial testing and we don't subscribe to the Federal Registrar, whatever it is. I don't claim to be an expert on the FDA, I don't have any restricted access to their resources. I only have access to what is released to the general public, same as you do. That's why each and every one of my statements included "as far as I know". Now I showed everyone where I'm getting my info - it's an official and recent (2007) FDA release, I think it qualifies as reliable. If you have any ACTUAL information on the subject, I would like to see it. Otherwise, you are just spamming the forum "like normal" and will be reported for that.
i was under the impression that the state of mass. uses 4 th gen testing, but hey i could be wrong, Like teak says it doesnt matter since 3 months is conclusive with 1,2,3,or 4
