Hey there, I am sorry you have Crohn's but I am relieved for you that you now know what is going on.
The ESR (Erythrocyte sedimentation rate) is an easy, inexpensive, nonspecific test that has been used for many years to help diagnose conditions associated with acute and chronic inflammation, including infections, cancers, and autoimmune diseases. ESR is said to be nonspecific because increases do not tell the doctor exactly where the inflammation is in your body or what is causing it, and also because it can be affected by other conditions besides inflammation. For this reason, ESR is typically used in conjunction with other tests.
Does that help explain a sed rate............it is only one tool to use in determining what is going on.
Gentle hugs to you and please know we are here for you.
