are proteins found in urine
— Vicky. Normally, the kidneys filter urine from the blood but retain protein, so there is not extensive loss of protein into the urine. Protein may be present in the urine because of acute inflammation or kidney stone disease, or as a sign of kidney damage.An inflammatory process, such as a urinary tract infection, could theoretically increase what we call nonspecific protein.f an underlying infection is the cause, the protein in the urine will usually disappear once the infection clears. If it turns out you have a persistent elevation of urinary protein, you'd be wise to have an evaluation by a nephrologist (kidney specialist) so he or she can figure out its source. Proteinuria is when protein is found in the urine. As blood moves through the kidneys, the kidneys filter out waste, excess fluid and salt. These wastes leave the body in urine. Usually, no protein is found in urine because most proteins are too big to go through the kidneys.If your doctor finds protein in your child's urine, it means your child's kidneys may not be working as they should--possibly because of inflammation (swelling).f there is only a little protein in the urine, your child probably has a benign (harmless) condition such as orthostatic proteinuria (see below). If a lot of protein is found in your child's urine, a more serious kidney disease might be the problem. Major urinary proteins (Mups), also known as α2u-globulins, are a subfamily of proteins found in abundance in the urine and other secretions of many animals. Mups provide a small range of identifying information about the donor animal, when detected by the vomeronasal organ of the receiving animal.ajor urinary proteins (Mups), also known as α2u-globulins, are a subfamily of proteins found in abundance in the urine and other secretions of many animals.

Protein in urine — known as proteinuria (pro-tee-NU-ree-uh) — is any excess amount of protein found in a urine sample.Protein is one of the substances identified during urinalysis, a test to analyze the content of your urine.Low levels of protein in urine are normal. Temporarily high levels of protein in urine aren't unusual either, particularly in younger people after exercise or during an illness.rotein is one of the substances identified during urinalysis, a test to analyze the content of your urine. Low levels of protein in urine are normal. Temporarily high levels of protein in urine aren't unusual either, particularly in younger people after exercise or during an illness. Albumin is a type of protein found in large amounts in the blood. Because it is a small molecule in size, it is one of the first proteins able to pass through the kidneys into the urine when there are kidney problems.This presence of small amounts of albumin in the urine is the condition called microalbuminuria.lbumin is a type of protein found in large amounts in the blood. Because it is a small molecule in size, it is one of the first proteins able to pass through the kidneys into the urine when there are kidney problems. Protein in urine (proteinuria). Protein in the urine, also called proteinuria, is often a sign of kidney problems, or an overproduction of proteins by the body.Healthy kidneys only pass a small amount of protein through their filters.rotein in urine (proteinuria). Protein in the urine, also called proteinuria, is often a sign of kidney problems, or an overproduction of proteins by the body. If there is only a little protein in the urine, your child probably has a benign (harmless) condition such as orthostatic proteinuria (see below). If a lot of protein is found in your child's urine, a more serious kidney disease might be the problem.Proteinuria doesn't cause pain. But when a lot of protein is in the urine, the level of protein in the blood may go down. This can cause swelling in your child's eyelids, ankles and legs.f there is only a little protein in the urine, your child probably has a benign (harmless) condition such as orthostatic proteinuria (see below). If a lot of protein is found in your child's urine, a more serious kidney disease might be the problem. The protein urine test measures the amount of proteins, such as albumin, found in a urine sample. Albumin and protein can also be measured using a blood test.he protein urine test measures the amount of proteins, such as albumin, found in a urine sample. Albumin and protein can also be measured using a blood test. In this article. People with proteinuria have urine containing an abnormal amount of protein. The condition is often a sign of kidney disease. Healthy kidneys do not allow a significant amount of protein to pass through their filters.roteinuria can also be a result of overproduction of proteins by the body. Kidney disease often has no early symptoms. One of its first signs may be proteinuria that's discovered by a urine test done during a routine physical exam. A protein urine test is used to measure the amount of protein in urine. Normally, healthy individuals do not have protein in their urine. However, when the kidneys are not working properly, protein may be excreted in the urine. protein urine test is used to measure the amount of protein in urine.
