Albumin is produced by the liver. It flows in the blood and helps in keeping fluid from leaking out of blood vessels, maintaining fluid balance. Albumin carries medicines, vitamins, hormones and other substances like calcium throughout the body. It helps in maintaining growth and also aids in tissue repair. Abnormal level of albumin is a cause for concern for physicians as it may indicate issues with kidney and liver functions.
