IDEXX laboratories makes a test for vets to use in house called the 3D Snap, it's a quick in house screening test for Lyme, Ehrlichia canis and heartworm.

The Lyme part of it uses C6 peptide technology. IDEXX also offers quantitative C6 testing as a follow up to see if canine Lyme treatment was successful. Their site implies that a drop below 30 indicates a successful Lyme treatment.

Since C6 testing does not seem to be used by the LLMDs I am curious why it's caught on for canine testing.

Any thoughts appreciated.

Thanks,

Janet

I'm afraid that I don't know much about this test, but, FWIW, the ID doctor who dx'ed Lyme for me used this test, as one of several.

Hi,

My first doctor who treated me for Lyme used this test. I had one about every 2 months and I feel that it was pretty accurate in showing the level of lyme load based on my immune response.

Unfotunately, this doc didn't treat properly for the coinfections and I didn't get better even though my Lyme load got lower. I've now been treated for Babs and am feeling a whole lot better.

I liked the C6 peptide assay. I thought it was really good. My latest doc hasn't tested me at all since the first time I went.

The C6 isn't considered a diagnostic test for humans for some reason. It's just never really caught on. The accuracy was shown to be pretty good in a few clinical trials. Better than the ELISA at least.

well, hate to get anecdotal on ya, but my C6 peptide test was negative even though my IgeneX Western was CDC positive. Go figure.

ps, Hi Corgilla, what Babs treatment did you take? thanks.

C6 was negative for me, while all other tests have been positive. Don't know what to tell you about that.

I don't put much faith in it.
