Just been tested for lupus as my symptoms have changed to joint pain and extreme headaches as well as fatigue. The autoimmune profile came back clear but the blood plasma viscosity came back high, its meant to be between 1.55 and 1.72 and mine is 1.88.
The GP has said that more tests need to be done but that they don't know what, so been referred to a neurologist.
Has anyone else experienced this or know what could be causing this?
p.s. my serum creatinine which was tested before my CFS/ME diagnosis has always been high but hasn't been tested recently, and an ultrasound was done in 2014.
