Low globulin will cause the body’s immunity to decline, it is recommended to find out the cause and active treatment. The reference value of normal human globulin is 20~35g/L. Globulin is synthesized by immune cells and is a mixture of many kinds of proteins, including more immunoglobulin and complement, multiple glycoproteins, metal-binding proteins, multiple lipoproteins and enzymes. Globulin is closely related to the immune function of the human body. When the body detects the invasion of pathogens, it will produce different amounts of globulin according to the characteristics of the pathogens to clear the pathogens, and when the amount of globulin decreases, the body’s immunity may be reduced, and the cause needs to be actively investigated and treated. Low globulin is mainly due to liver disease, low immunity and hereditary factors, it is recommended to actively investigate and treat the original disease; some malnourished people may have low globulin due to low protein intake, it is recommended to eat foods rich in animal protein and vegetable protein, such as eggs, milk, beans, etc. When low globulin is detected, it is recommended to consult a doctor in time to have a professional doctor to evaluate and formulate an individualized diagnosis and treatment plan, so as to avoid delaying the condition.
