Serum Viscosity (SV)

Serum viscosity test is similar to whole blood viscosity test, but the method is simple, and can avoid the influence of red blood cells and other factors, and the effect of plasma protein concentration is very small, so it is sensitive to multiple myeloma and hyperglobulinemia. Sex is higher than whole blood viscosity. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: The serum lipids in newborns are very low, so the serum viscosity is very low. Normal value: Serum viscosity (SV): 1.4-1.8 Above normal: Plasma viscosity is also elevated. negative: Positive: Tips: After taking blood, you need to press it at the pinhole for 3-5 minutes to stop bleeding. Normal value Relative viscosity (serum flow time / time of distillation of distilled water) 1.4 to 1.8. Clinical significance When the relative viscosity is >4, it is suspected to be a high-viscosity syndrome. When the relative viscosity is >6~7, obvious accompanying symptoms may appear. In particular, the serum lipids in newborn serum are very low, so the serum viscosity is very low. High results may be diseases: precautions for children with high viscosity syndrome 1, higher than the reference value, mainly related to elevated serum globulin and lipid concentrations. 2, the blood lipids in newborn serum is very low, so the serum viscosity is very low. 3. When the serum viscosity increases, the corresponding whole blood viscosity and plasma viscosity also increase. Inspection process Steps: 1. Turn on the instrument to warm up and let the constant temperature system reach the test temperature. 2. After the sample is kept at the test temperature for 5 minutes, mix well and add to the sample cup. 3. Press the measurement button and the shear rate is measured in order from high to low. In order to avoid the sinking of blood cells, the choice of shear rate should not be too much, and the retention time should not be too long. 4. After the sample is measured, the sample cup should be cleaned and dried. Not suitable for the crowd No taboos. Adverse reactions and risks Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
