What could happen if Albumin found in urine?

Answer 1

Albumin is a protein. It would depend on the amount of albumin and your activity levels. For instance, if you just ran a marathon and had traces of albumin in your urine, it would most likely resolve on its own and cause no problems.

Answer 2

Albumin is a protein present in the blood. Proteins are normally absent in urine because the kidney cells generally prevent large molecules including proteins, from being excreted.

Albumin in your urine may be an early sign of kidney problems although some people have small amounts of albumin in their urine normally. However if the amount increases this can be a sign of kidney problems and would be monitored closely by your doctor to ensure that no serious kidney damage occurred.
Albumin is the main protein in the blood stream. It's main job there is to keep fluid inside the blood vessels and not leaking out into the space between the blood and cells AND the cells themselves.

Normally, it is too big a molecule to leave the blood and go into the tissues (the space) or the cells. This is the same for when blood (with albumin of course) gets to the kidney through the blood.

In the kidney, the blood flows through the capillaries (teeny tiny blood vessels) and into millions of structures called "Bowman's Capsules". The blood pressure in the capillaries causes the fluid part of the blood (along with small molecules like sodium, potassium, etc.) to leave the blood and go into the Bowman's capsule and then into the tubes of the kidney (It is called "filtrate"). Through absorption back into the body from these tubes (water, sodium, potassium, etc), the filtrate eventually becomes urine and then is excreted through the bladder.

As said in the second paragraph above, normally albumin would not leave the blood vessels, including in the Bowman's capsule of course. If the kidney is damaged or sick (renal insufficiency or renal failure), the capillaries in the Bowman's capsule fail to do their job of keeping the albumin in the blood vessel by becoming "leaky". In other words, there are then gaps in the capillaries that will allow the larger molecules (in this case albumin) to leak out of the capillaries and into the filtrate. They don't get reabsorbed back into the body (again, too big). So, they then leave the body through the urine. Thus, your "albumin in the urine".
Albumin (al-BYOO-min) is a protein found in the blood. A healthy kidney does not let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine. The less albumin in your urine, the better.

It would be best to consult your doctor on this issue. It could be related to kidney disease.
