I know that only a test at 12 weeks is considered conclusive. Can you pls answer the following questions.

1. What % of people as per your opinion will seroconvert in 6,8 & 10 weeks respectievely/

2. what is the cut of ratio in ELISA test mean? If your reading is negative and very close to the cut of (that is 0.807 when cut off is 0.9), does it mean that you are probably going to seroconvert in a few days.

[Teak]

Yes.

Thanks Teak. Does this also mean that a normal person without any exposures can get a negative result with even 0.99 as the ratio?

[Teak]

That is not what I said. I said everytime you test your result will be different. The only concern would be above 1.0,

[ma_ni123]

i have a little confusion here on your answer. you said "Yes" means 0.99 has a greater chance of becoming positive in future. You also told that it would be different every time. can you pls clarify. Sorry for not able to understand properly.

[Teak]

Yes and everytime you take the test the numbers will be different.

[ma_ni123]

Thank You Teak.

Can you pls give me your opinion for my first question.

Also, what does this reading in Elisa Mean? for example in a negative you can have a 0.1 as well as 0.99. is the second reading indicate that you have a greater chance to become positive in future?

The cut off on an ELISA is 1.0 anything under 1 is negative.
