Quest test

[CaliGuy79]

Hi Terri,
I’m confused about the kind of test Quest performs. I received a 1.27 for HSV2 and negative for HSV1 from Labcorp on my first test and they said they are out of kits for the confirmation. I then went to Quest and it sounds like I took a HerpeSelect IGG Inhibition ELISA for my confirmation. I have not seen the result of the confirmation yet. What is the chance this confirmation comes back negative?

Is this confirmation test the same thing as a Biokit? I read the study (2005 Morrow, et al.) that makes it sound like the HerpeSelect ELISA test is highly inaccurate, especially for my low index score. Is Quest really giving a test with minimal accuracy as the confirmation test? Or am I missing something?

Other than the WB, is there another option I can take for the Biokit or similar alternative?

With a 1.27, there is an 85-90% chance that this is a false positive.
The quest confirmatory test is not the biokit. It is called the inhibition assay, as you know. That is not the test described in the Morrow paper, it is the IgG you’ve already had done. We have seen both positive and negative IA in comparison to negative western blot. I know of no other test that will be helpful for you as confirmatoy testing.

Is there a place I can find a list of facilities that will process the blood so I can send it to UW?

First, you’ll need to identify a provider to order the blot – you can work with your own health care provider and UW to get this or with me – both are just fine. When I work with patients, we use anylabtestnow and ARC point labs for blood draws.
