roxie60 - Vacutainers look like they're the same around the world. So that shouldn't be problem.
Do you mean mycoplasma fermentans? I don't see anything on google regarding chlamydia fermentans.
I'd go with the LTT test over the igenex. Typical ways of measuring Lyme infection can take a very very long time after improvement to show any change. Whereas LTT is supposed to be better at that, from what I recall.
LTT probably isn't accepted by the CDC. It's a relatively new test (though validated in studies), and CDC prefers to maintain as much denial as possible when it comes to certain disease.
I don't know what got marked on my form. It probably didn't say to send them to the patient, which would explain why I couldn't get the results from them directly. If it says they can release it to you, then I'm sure they will.
When choosing tests, I think the most important aspect is too look for potential underlying or causative infections. So
1) can that infection cause your symptoms?
2) can that infection become chronic?
3) could you have realistically been exposed to that infection?
4) will a positive result for that test be helpful for selecting treatment?
5) will a positive result be helpful for proving disability or illness?
6) has it been shown to be a problem for some other ME/CFS patients?
IgG results will prove absolutely nothing to people assessing disability. Insurance companies and many practitioners will simply interpret even an extreme result as being a past infection and immunity against future infection.
Toxoplasmosis probably can't cause immune dysfunction - in certain countries, something like 50% of the population has had it at some point, but only have problems if there's already immune dysfunction present. Hence it might be an opportunistic infection, but is unlikely to be causitive. And if your cat is an indoor one, it probably wouldn't have it, and you not eating undercooked meats would also make you very unlikely to get it.
Lyme is definitely a suspect in your part of the world, especially with you testing at least partly positive. Hence it makes sense to test LTT Lyme, and co-infections.
HSV is Herpes Simplex Virus 1 & 2. Not the same as HHV or any of the other Herpes viruses. Most people have had at least one these, so they're unlikely to be causative and more likely to be an opportunisitic flare-up. But again, an insurance company would likely dismiss elevated IgG, so not too interesting.
It sounds like chlamydia pneumonia would typically involve respiratory symptoms, and chlamydia trachomatis would typically involves sores at the site of infection (usually genitals) or pelvic inflammatory disease. Again, both of those seem somewhat unlikely.
So basically I think it makes the most sense to focus on Borrelia and its co-infections, out of the options listed. Hard to say if that will prove disability though - the best bet for that is probably a CPET, the two-day one if you're relatively functional.
