The reference range of normal values for the white globule ratio is usually between 1.5 and 2.5. Albumin to globulin ratio is the ratio of albumin (ALB) to globulin (GLB), usually written as A/G. Albumin to globulin ratio is an important reference indicator in liver function tests and reflects the synthesis function of the liver. Albumin is synthesized by the liver and enhances the immunity and resistance of the body. Globulin is produced by the body’s immune organs, and the amount of globulin represents the level of the body’s immunity. Normal people rarely have a low albumin to globulin ratio, and an albumin to globulin ratio below 1.5:1 is common in diseases such as cirrhosis and liver insufficiency.
