Hi All:

I'm curious to learn more about the what cd57 test results mean. My number was extremely low "8". This in conjunctin with many Lyme symptoms, an equiv. Western Blot, a borderline positive for erlichiosis and a positive Bowen bone biopsy test have led us to the the Lyme treatment path.

My Lyme tests done by regular docs have all come back as negative: Elisa, PCR for Erlichiosis, spinal tap.

Of course reg docs say I have no lyme disease, they dx depression and fibro.

Right now our only option is to go with the llmd's, we've started a course of rifampin and ketek.

I have been on abx for the past year but not at high doses nor extended courses. The longest was 8 weeks on iv rocephin but only 75ml/day.

Hopefully the highdose/extended course will be the answer.

I have been bedbound since Sept 04 and slowly declining since last April. I have a 3 year old son. So needless to say life has been tough.

Thanks for any insight on the cd57 test.

Regards, Lisa

A count under 10 definately shows chronic Lyme as normal people have counts generally over 180 to my understanding.

I actually thought co-infections made the count a bit higher ...for instance I have Babesia and Bartonella and have had these infections 15 yrs but my first CD57 was 53.

Most LLMD's use Rocephin in combination with other oral abx to get all the Bb forms. Also make sure you stay on abx until your CD57 goes over 180 to prevent relapse.

if on a regular differential my lymphocytes were at 1, would this mean that I would score a low number on a specific cd57 test?

Research the link between cortisol and NK cells.

If this is the same test I had 4 yrs ago, mine was 14. I'm now doing very well.

Lisa, I would be aggressive with this. It sounds like your only hope of recovery. And that's worth alot to your 3yr old!

Agreeing mostly with Cave - remember the CD57 is a **marker** only!!!!! Don't put more validity in it than that. It shows trends in people overall - but not totally accurate for each person! But unlike Cave said, my daughter who is significantly disabled with LD has frequent counts of 0 - zero!!!! We look at it with interest - but not total validity - we look at how she is doing overall - not on these numbers!
