IGG Accuracy for HSV1 Confusion

I've read that HSV IGG tests miss between 10-15% of HSV1 infections. Does this mean that 10 to 15% of people will consistently test negative for HSV1, or that the test provides false negatives for HSV1 10 to 15% of the time? Curious because if its the latter, you would think numerous negative tests would rule out this inaccuracy.

Additionally, does anyone know if Western Blot HSV testing is available in Ontario with a doctors requisition?

These Dr's are not here anymore. You can find them at the anerican sexual health association.  They charge $25 a question with two follow up questions. Well worth the money.

So an update.. New recurrence of the genital infection i've been dealing with for the past year. Lasted about 2 weeks in total this time, with spots lasting 2-3 days each but popping up in new areas.
Negative swab (likely not fresh enough) and negative combo IGG EIA test again, done at 3, 6, and 12 months post exposure. Spots seem to recur in the same spot time and again.. red shiny bumps on foreskin which swell and drain, without ulceration (or very small, perhaps). Resembles certain (mild) HSV images found online. Head of STD clinic in my city claims that it visually does not resemble HSV but fungal infection, or possible psoriasis. It seems to me as if fungal usually affects the glans though, while my issues are only on the foreskin. Any further thoughts on this would be appreciated. Western Blot and PCR swabs are the plan going forward I suppose, but the WB seems quite difficult and expensive to obtain.  
I'd love to hear from Dr. Hook / Dr. HHH from the expert forum if at all possible, as i've been dealing with this issue for quite some time. The nature of a recurrent genital infection reoccurring in similar areas makes it difficult for me to accept the test results, although i've had many.

Yes it is in excess of 99% for both HSV1 and HSV2.

Just curious where you read that HSV IGG test miss 10-15% of HSV1 infections? I'd like to read more about that. I was diagnosed with genital hsv1 and have only slept with my husband, but somehow his Igg came back negative....

There is research into this often undertaken by the manufacturers of the tests. They need to publish specicivity of the tests and report this aorund 90% for HSV1.

Then why isn't western blot used more often at all clinics?

Considering looking into the Western Blot but i've also had numerous negative swabs which were taken >48 hours of onset, one of which was PCR... We'll see. Difficult to get WB in Canada.

The western blot picks  will pick up how many of the missing 15%

Pretty much all of them, testing of swabbed positive people with HSV1 reveals that over 99% test positive with Westernblot.

This is not fully known, but I believe it weighs more toward people never revealing a positive over successive tests.
I have heard of people in Canada being phone patients of Terri Warren obtaining the WB, equally I do not see why a Canadian doctor cannot follow the process described on the UofW website. Print this out and take it with you to the doctor.
