For four years after being diagnosed with RA I kept hearing "your sed rate is not elevated."  I have a blood disorder and it's in my chart. Well I researched online and guess what?  A sed rate cannot be done on a patient with spherocytosis because it will give a false reading.  Of course it will but why didn't anyone else know it?

There are other diseases that affect the sed rate and I wonder if other patients know enough to research their own diseases and lab results.  To date I have informed pathologists, family medicine docs and rheumatologists.  Don't expect anyone to have all of the answers and be very diligent....trust your own common sense.
