                        Hi Michelle,       I am so sorry to hear that your Mother is not doing well and that she has Polymyalgia Rheumatica.         You asked about another blood test, but I am unclear as to what blood tests your Mother has had.  I can only tell you from my experience with PMR.  I had several blood tests to rule out such things such as Lyme Disease and Lupus, but I can't remember what they were called, since my tests showed that I didn't have those diseases.  Those initial blood tests were taken along with some tests that showed that I had PMR.  The PMR blood tests were C-Reactive Protien and the Sed Rate.  Both of mine were  fairly high.       I hope your Mother feels better very soon.  I recommend that she see a rheumatologist.         Best wishes!  Shar
