The program is called The Lyme Test Access Program (Lyme-TAP)
This is a program that helps with up to 75% of testing fees for those who qualify. Wouldn't hurt to look into it.
From their site,
"This nationwide assistance program was made possible by a very generous donation from IGeneX Inc., a CLIA/Medicare licensed laboratory. Any CLIA/Medicare licensed laboratory may be selected for testing: you do not have to use IGeneX for this program."
Hope this helps.
