can someone tell me what this means..its on the result slip.
lyme immunoblot testing is only indicated if screening lyme igG antibodies are positive
as from 9th sept 2014 lyme serology will be performed on the liaison and immunoblot by euroimmun assay
It means that you got the least sensitive of the tests - Lyme serology. They are usually called either ELISA or IFA.
" Tests for Lyme disease using IFA have received mixed reviews and some authors believe that the interpretations of IFA assays are overly subjective and that the tests are either functionally insensitive for Lyme-specific antibodies or display considerable cross-reactions with antibodies to other spirochetal organisms."
"Most commercial ELISA tests have comparable sensitivity and specificity because they were made to compare to one another for the FDA 510K process. However, most are inadequate as a screening test because they were not designed by the manufacturers to be sensitive at the 95% level, which is required for screening."

And I've never seen the "ChLIA" testing before. From what I can find, it's a virus though, not Lyme but the Human T-lymphotropic virus.
