Need help with additional test Lyme testing

Would sticking to the local labs for co-infection testing make sense (which is all free) or would buying full co-infection panels from Igenex (upwards of about $1000+) make sense?

Also, I know a lot of people here have done testing through Igenex so I almost want to do it just to have it, but at the same time if I do the full Lyme panel it's going to cost around $600.

Do I really need the additional Igenex tests? I already tested positive for the C6 peptide twice, also had IgM 31, IgG 41, and IgG 72, and tested positive for babesia duncani. The western blots are considered negative. I believe this is because I've had symptoms for 10 years so the Lyme knows how to hide.

Thoughts?

I know many here have done Igenex testing, but why the hell is it so expensive? Could cost about $1,500 for full Lyme and co-infection panels...

Stony Brook is reasonable. They were covered under my insurance which is good. Oddly, they don't do co-infection testing which is unfortunate since they are a top ranked Lyme lab. And their western blot tests aren't as detailed as Igenex. They only say positive or negative for a band. My western blots are basically negative which is why I was considering Igenex. Although I thought chronic Lyme can make it difficult to test positive on western blots. I wonder how that will change now that I've been on antibiotics for 3 weeks.

I am also consdering another Igenex WB test since first one was CDC negative. I really want a test that supports what I have been going thru especially since that is what is important to insurance companies. I was on abx for 6 weeks and now off for 3 weeks. I feel slightly better but afraid I'll spend the money and nothing new with show up. So frustrating.
