We just found out that our blood sample took 5 days to get to the lab. IgM and IgG turned up negative under CDC criteria but positive under IGeneX. Also, CD-57 was 9. How does "stale" blood affect the test results? Anyone know?

Hey there...
Welcome to LymeNet!
I do know old blood is bad if doing babesiosis tests. But I've not heard anything about it affecting Lyme tests. It could... but I've not heard any thing about that.
i suggest you call igenex and ask the question there. many lymies have talked to DR. HARRIS in the past! just an idea where he could explain this in user-friendly terms.
WHO and where was the hold up on blood??? ****************************************
