I don't recall a lower limit on sed rate (whcih doesn't make sense to me), but anyway, my first blood test was 1 mm/h. On one of the health pages it mentioned that low sed rate is common in CFS patients. I mentioned this to the ID and he had never heard of this correlation. I got remeasured and it was 4. So maybe the test itself is also not so consistent. My LLMD didn't comment on my sed rate being low as an indication (for or are against) Lyme.
I read what jason80 did. Remember, tests are ususally negative in lyme disease.
How low is your sed rate ? If your sed rate is between 0-3, then I can tell you this is common in CFS and not too common in healthy individuals.
Interesting. Well here is the source on low (but normal) sed rates in CFS patients. Dr. Cheney explains somewhere (over the internet) why this happens, but I can't remember what that reason was
.Sed Rate (ESR) --- The most consistent laboratory abnormality in patients with CFS is an extremely low erythrocyte sedimentation rate (ESR), which approaches zero. Typically, patients with CFS have an ESR of 0-3 mm/h. An normal ESR or one that is in the upper reference range suggests another diagnosis.
