  • Answer
Albumin is a carrier molecule in the blood that helps transport many types of molecules, especially molecules that are not water soluble. Albumin also plays an important role in maintaining the osmolality of the blood, thereby contributing to fluid balance in the intracellular and extracellular spaces.
Normally albumin is not excreted by the kidneys, so an increased amount of albumin in the urine (albuminuria) will result in less albumin in the blood (hypoalbuminemia). A nephropathy can cause the loss of albumin to exceed the liver's ability to replace it.
