serum viscosity

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 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 / distilled water flow time) 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: multiple myeloma considerations (1) The reason is higher than the reference value, which is mainly related to the increase of serum globulin and lipid concentration. (2) The blood lipids in newborn serum are very low, so the serum viscosity is very low. (3) When the serum viscosity is increased, the corresponding whole blood viscosity and plasma viscosity are also increased. Inspection process (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 descending order. 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 each 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.
