The decrease in the ratio of albumin to liver function is mainly caused by the following two reasons: First, the lack of albumin synthesis ability while the level of globulin is normal, commonly found in pregnant women, who consume too much albumin during pregnancy, so it leads to a decrease in the level of albumin in the serum. Chronic kidney disease glomerulonephritis albumin is excreted from the urine, which also leads to a decrease in the level of albumin in the blood. In severe liver disease and cirrhosis, the lack of albumin synthesis capacity will also result in lower levels. Second, the albumin level is normal, but the globulin level is elevated. It is recommended to do protein electrophoresis to see which specific type of globulin is elevated. The common ones are multiple myeloma, lymphoma or tuberculosis, neoplastic diseases, severe liver disease, etc.
