Should protein in the urine be ignored? Sometimes protein appears temporarily after strenuous exercise, fever, dehydration, or an illness. But when it remains elevated, it may be an early warning of kidney damage—even when your kidney function blood tests still look normal.
In this video, Dr. Kevin Lowe explains:
• Why protein can leak into the urine
• The difference between albuminuria, tubular proteinuria, and overflow proteinuria
• What your urine albumin-to-creatinine ratio, or UACR, means
• Why a regular urine dipstick may miss smaller amounts of albumin
• When an abnormal result should be repeated
• How persistent albuminuria is connected with kidney disease, heart attack, and stroke
• Steps that may help reduce albumin in the urine and protect your kidneys
If you have diabetes, high blood pressure, reduced kidney function, or another risk factor for kidney disease, ask your doctor whether you should have a urine albumin-to-creatinine ratio. This simple test may uncover kidney damage before routine blood tests do.
One abnormal result does not necessarily mean that you have chronic kidney disease. Your result should be confirmed and interpreted along with your estimated GFR, blood pressure, medications, medical history, and overall health.

00:00So, protein showed up on your urine tests.
00:03Should you be worried or can you safely ignore it?
00:08Sometimes, protein in the urine is temporary,
00:12occurring after strenuous exercise or fever or dehydration.
00:18But when it persists, it may be one of the earliest signs of kidney damage,
00:24even when your kidney function and blood tests still appear normal.
00:31It can often signal a higher risk of heart disease and stroke.
00:37In this video, I'll explain what causes protein to enter the urine,
00:43what the numbers mean, and what you should do if your result is abnormal.
00:50Urine can contain several kinds of protein.
00:53The protein doctors most often measure is albumin
00:58because increased albumin excretion is a sensitive marker of damage to the kidney's filtering system.
01:08Albumin can get into the urine when the tiny filters in your kidneys become damaged and start to leak.
01:17This can often occur in autoimmune diseases or chronic diseases such as diabetes or hypertension.
01:26Protein can also show up when the kidney tubules are damaged.
01:30These tubules normally take back proteins that pass through the filters.
01:38If they're not working properly, some of the protein ends up in the urine.
01:45Sometimes, there's simply too much of a particular protein in the blood for the kidneys to handle.
01:52This can happen with antibody proteins as in multiple myeloma or with myoglobin released in serious muscle injury.
02:01Not every protein in the urine is abnormal.
02:05The kidneys normally release a protein called uromodulin, which helps prevent urinary tract infection and performs other kidney functions.
02:15So, how do doctors measure albumin in the urine?
02:18They usually use a test called the urine albumin to creatinine ratio or UACR.
02:27This test helps correct for whether your urine is very concentrated or very diluted.
02:33A result below 30 is considered normal to mildly increase.
02:40A result between 30 and 300 is moderately increased.
02:46And a result above 300 is severely increased.
02:51A regular urine dipstick may miss smaller amounts of albumin.
02:56That is why the UACR is usually the better test for finding early kidney damage.
03:02But don't panic over one abnormal result.
03:05Exercise, fever, dehydration, infection, menstruation, and other short-term illnesses can temporarily increase the amount of albumin in your urine.
03:18Your doctor will usually repeat the test before deciding that there is an ongoing problem.
03:26So, as you can see, protein in the urine can have tremendous significance and can signal an increased long-term
03:36risk that may prompt further evaluation and management.
03:42The important thing to remember is that protein in the urine should not be ignored.
03:48But one abnormal result does not necessarily mean that you have kidney disease.
03:55If the protein remains elevated, treating the cause can often bring it down and help protect your kidneys and your
04:04heart.
04:06That may mean controlling your blood pressure or your diabetes, reducing salt, managing your weight, taking the right medication, or
04:17avoiding medications that may harm your kidneys.
04:20So, if you have diabetes, high blood pressure, reduced kidney function, or another risk factor for kidney disease, ask your
04:32doctor about the urine albumin to creatinine ratio.
04:36It is a simple test, but it may uncover kidney damage before your regular blood tests do.
