Probably first generation test? Cobas Mira

[someone1]

Hello,

i hope this will be my last question in the forum as i m waiting on monday my almost conclusive test. I was tested arlready negative at 7 weeks.

I found that my test was done in a "Cobas Mira" series diagnostic machine, made by the french company Roche. Do you have any idea what elisa generation it uses? From what I find, these diagnostics machines were out on the market in the first years of 1990'. So I am afraid that my test was a first generation.

Does anybody knows if an old diagnostic machine can run a newer elisa if it is provided with "modern" materials?

Anyway all these have no great meaning as in 2 days i ll take my results. But i would like it so much if  i 'd learmed that i could find some reliability in my 7 weeks test.

Hard times...

thank you

Can't be of much help, but here's a clinical study that used a Cobas Mira.  It's not an HIV study, but it was in 2001.

My best guess is that the machine CAN do 2nd and 3rd generation ELISA tests, but it's only a guess.  You'll have to ask the Dr's or possibly someone else knows here for sure.

What i mean is, can an old diagnostic instrument perform a test using more modern eliza assays?

thanks again

Hello Teak, thanks for the reply.

I know that a 7 week test is not conclusive, this is why I took another one today close to 3 months. When i was at the labratory (private) i noticed the "diagnostic machine" that possibly my test was performed.

I am anxious waiting the results and i try to find some optimism this why i ask about "generation question". Of course the result is all that it counts, and the result is the one of the three months, but it would be good for my anxiety if i knew that this "cobas mira" performs the so called in this fourm "modern test".

I know that my question is very specific but do you know anything about? Could a diagnostic machine of 90's perform a more up to date elisa test or it performs only the tests of its time.

thanks

A 7 week test is not conclusive if that is what you wanted to know. A test taken at 3 months is conclusive.
