25 Replies: 1  Well, first of all, you are not alone. Ha ha, second of all, I don't have an answer for this. 2  Have you been tested for glaucoma. If not get yourself tested by an ophthalmologist, not an optician. 3  I don't think my problem is that serious.... I mean becoming blind.
So, the calculated normal reference value of whole blood viscosity (230 s â 1) of old women in Beijing can be obtained, and it is 4.85 Â± 0.55 (mPa Â· s), the normal reference value of whole blood viscosity is in the range between 4.30 (mPa Â· s) and 5.40 (mPa Â· s).
Blood viscosity is determined directly by four primary factors: hematocrit, RBC (red blood cell) deformability, plasma viscosity, and RBC sedimentation/aggregation. The effect of hematocrit makes intuitive sense â the more blood cells that one has, the thicker one's blood is going to be.
