What could cause a false positive with a treponemal cia serum test?
A doctor has provided 1 answer
Lyme disease and...: False positives for this test are extremely common. See http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6005a1.htm There are many possible causes- see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2095002/table/T4/ for a list. I would be particularly concerned about Lyme disease causing a false positive and advise a Western Blot from IgeneX lab. See http://betterhealthguy.com/lyme/testing
