Erythrocyte Sedimentation Rate (ESR)
Erythrocyte sedimentation (ESR) is nonspecific test for various diseases.
But I have seen it has value in the diagnosis of various diseases.
If someone complain of vague symptoms,in that case advise ESR. If ESR is raised, it indicate definitely patient has some underlying diseases that may be infections or cancer.
It is raised in the chronic inflammatory diseases, autoimmune diseases and malignancies.
ESR is usually slightly higher in old age.
This test may be used to monitor the autoimmune disease like Systemic lupus erythematosus (SLE).
This test may be helpful to support the diagnosis of temporal arteritis, polymyalgia and vasculitis.
I will suggest if you have patient with history of weight loss, body pain and aches or vague symptoms advise ESR.
