can a positive swab but negative western blot happen?

I have a few questions:

1. If someone has a positive swab, but negative western blot, does that mean its still herpes?
2. If someone has a low IGG (less than 3.5). negative western blot, positive swab, is that even possible? If so, why does that happen?
3. If someone has a low IGG (less than 3.5), but consistently negative western blot, is that a correct result?

I have a low IGG, and I am waiting for the western blot test result. I could not swab test since it was scabbing already. But can #2 for some people?

Btw, I forgot to add, when I had the encounter on Oct 18, the week later I saw scabs on the underside of my penis. I went to a clinic and they said it does not look like herpes, but when they did a swab test they said it was scabbing and they could not do it. I was sensitive in that area before all this (when she gave me a handjob), and I am not sure if it is herpes.

Well I can give a timeline and maybe you can decide if enough time has passed:

Oct 18 2014 - encounter

Nov 24 2014 - IGG test, and the results came next week:

hsv 1 >6
hsv 2 1.85

I went ahead and did another IGG test at the same place thinking it could be a false positive after reading online.

Dec 22 2014 - IGG test, and the results came next week:

hsv 1 >6
hsv 2 1.87

At this point I was scared and the doctor said it is herpes positive and no other tests are required. Now, when the results came back (last week of December 2014), the same week I was not feeling well and I may have gotten sick. But I noticed a bump on my penis and thought maybe this is an outbreak. I went to different clinic, and they said it isnt herpes. They took another blood test for labwork and the results came back next week (I didnt get a copy of it so I dont know the full story). I asked the nurse on phone and this is what she said:

hsv 1 8.00  (high)
hsv 2 3.1  (high)

Now at this point I was depressed and very scared of what is happening. On Jan 19 2015, I went ahead and took the hsv western blot, and maybe tomorrow I will know the results. Would you say I have waited long for this?

I thought maybe that last week of December was where I was become fully positive, and maybe the western blot would detect it. About the encounter, there was no vaginal, but there may have been oral but I dont remember. All I remember was a handjob, and I fingered her and kissed her breast. If I am showing for hsv 2, wouldnt it be possible that she may have touched her genitals and then touched my penis? And if fingered her and had fluid, wouldnt I get finger herpes? Nothing happened on my fingers.

Fleet is correct that the only issue or cases known where the WB missed an infection deals with HSV1. I would agree about 10 cases or so where this has happened and a swab positive result confirmed an HSV1 infection with a negative WB via blood.

I would also say that for HSV2, I would take this result as definitive as well if it has been 5-6 months post exposure, as the U of W will tell you yourself that its 99% accurate if taken 6 months or beyond from exposure.

So you have a low IGG? If so, what was the score and for what type again?

Please post your results when you get them. I would be interested in seeing them.

Yes excessively rare issue with WB and HSV1 only. I am not aware of any issues with HSV2, not a single case.

Alright, so these cases happened for hsv 1 and not 2? I will be getting the results very soon and I am getting worried.

The HSV2 test is extremely accurate. The answer will be definitive. You read all sorts of stories on the net, this doesn't mean they have herpes, it usually means they don't.
