Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Expert:  Dr. David replied 9 months ago.

The "index value" (also called the "signal-to-cutoff ratio") is a technical term having to do with how this type of HIV-antibody test is conducted.

Values less than 0.90, are definitively negative.

Values between 0.9 and 1.0 would be equivocal or borderline.

And values above 1.0 would be preliminarily positive. These preliminarily positive (or provisionally reactive) tests require a confirmatory test before someone is told they are HIV positive

does your index value say you are preliminary positive or equivocal?

Customer: replied 9 months ago.
It actually does not say one way or the other
Expert:  Dr. David replied 9 months ago.

can you take a photo of your test results and upload them here?

Customer: replied 9 months ago.
I can but it will be a little bit
Expert:  Dr. David replied 9 months ago.


Customer: replied 9 months ago.
it wasn't an HIV. It was HSV
Expert:  Dr. David replied 9 months ago.

right herpes type 1 and 2 virus.

there still should be an explanation of what the index results mean.

Thanks for using

Customer: replied 9 months ago.
Here are the results we were talking about
Expert:  Dr. David replied 9 months ago.

that is not the complete blood tests results.

you need to ask your doctor to get the complete blood results from the herpes blood antibody test results.

Customer: replied 9 months ago.
I didn't think so either. But what does that number represent?
Expert:  Dr. David replied 9 months ago.

it represents the "signal-to-cutoff ratio" and the likelihood you could have herpes virus.

but you need the full test results for antibody IgG and IgM levels for both HSV1 and HSV2

the full report will show this

you could have herpes type 1 virus which causes cold sores in your mouth and fever blisters.

and this could cause a index level of 12.5 for herpes type 1 virus.
