Tactile bead protein, also known as bound bead protein, is found in serum and body fluids, with normal values ranging from 1.0 to 2.7 grams per liter. Binding beads below 1.0 g/l are potentially dangerous. Haptoglobin is an alpha 2 globulin synthesized by the liver, accounting for about 1% of total plasma protein, which binds to hemoglobin in the plasma to form a stable complex. When hemolysis occurs, there is an increase in free plasma hemoglobin, an increase in the amount of bead protein bound to it, and a decrease in plasma haptoglobin, which is a very sensitive indicator of intravascular hemolysis. This is a very sensitive indicator of intravascular hemolysis. A low level of conjugated albumin is often seen in hemolytic anemia, megaloblastic anemia, acute and chronic hepatocellular diseases, infectious mononucleosis, and congenital unconjugated albumin hemorrhagic disease. If you have a low binding protein, you should go to the hospital in time to find out the cause of the disease and take targeted treatment under the guidance of the doctor.
