Is there any benefit to checking serum viscosity in patients with autoimmune disease and headaches/migraines to see if aspirin or clopidogrel may be beneficial?
SLE, APLS, Sjogrens, and RA can sometimes have associated serum hyperviscosity. Is the standard viscosity test sensitive enough for these conditions and, if so, would standard hyperviscosity treatments be beneficial?

The serum viscosity test measures the time required for the serum to flow through a calibrated capillary tube under controlled pressure. Clinically significant elevations in viscosity (≥2.5 centipoise, normal range 1.4 - 1.8 cP) can cause symptoms and are most commonly seen in hyperviscosity syndrom...
