Albuminuria, or having far too much protein in your urine, is a symptom of renal illness. Blood contains the protein albumin. Albumin cannot cross from the blood to the urine in a healthy kidney. Some albumin can leak into the urine as a result of renal injury. The better, the less albumin there is in your urine.
Symptoms and signs
Although it normally has no symptoms, there may be yellowish foam in the urine. If severe albumin losses result in low blood protein levels, swelling of the face, hands, tummy, or ankles may happen (nephrotic syndrome).
Albuminuria can be a sign of renal disease or an excessive salt consumption since the kidneys generally do not filter big molecules into the urine. Patients with chronic diabetes, particularly those with type 1 diabetes, are also susceptible. Reclassification of renal disease (CKD) according to etiology, glomerular rate group, and albuminuria category was done in accordance with recent international criteria (KDIGO 2012). (A1, A2, A3). 
The quantity of protein excreted can be used to distinguish different albuminuria causes.
An average person with nephrotic syndrome excretes 3.0 to 3.5 grams per 24 hours.

Microalbuminuria, defined as between 30 – 300 mg/24 hours, mg/l of urine, mg/mg of creatinine, or a combination of these, might be a precursor to diabetic nephropathy. Since there is neither a “little albumin” (microalbuminuria) nor a “large albumin,” the term albuminuria is currently favored in nephrology (macroalbuminuria).  A1 denotes a urinary albumin/creatinine ratio that is normal or only mildly elevated (30 mg/g or 3 mg/mmol); A2 denotes a moderately elevated (30 mg/g or 3 mg/mmol; formerly known as microalbuminuria) urinary albumin/creatinine ratio; and A3 denotes a severely elevated urinary albumin/creatinine ratio (>300 mg/g or 
Why is albumin in urine significant?
Urinary albumin measurement is a crucial tool for
the detection of kidney illness
tracking the development of kidney disease
As part of a typical physical examination, healthcare professionals frequently check patients for albuminuria and keep monitoring urine albumin in those with renal disease.
If the amount of urine albumin remains unchanged or decreases, therapies may be effective. The likelihood that kidney disease may develop to renal failure may be reduced by treatment that decreases the urine albumin level.
Renal disease is more likely to affect individuals who have diabetes, a high blood pressure, cardiovascular disease, or even a family history of renal failure. How frequently you should undergo a pee test for albumin should be discussed with your doctor.
How may albuminuria be found out?
A urine dipstick test, followed by a pee albumin and creatinine measurement, is frequently used by a healthcare professional to check for albuminuria.
In the clinic of your doctor or another medical facility, you will be requested to produce a urine specimen in a particular container. The sample is either tested on-site by the office or facility, or it is sent to a lab for evaluation.
Test for albumin using a dipstick. The amount of albumin in the urine may be found using a dipstick test on a urine sample. A nurse or specialist injects a dipstick—a strip of paper that has been chemically treated—into the urine to conduct the test. When protein is in the urine, the dipstick’s color changes.
measurement of albumin and creatinine. This measurement is used by a healthcare professional to calculate the ratio of albumin to creatinine in the pee and to assess how much albumin is expelled in a 24-hour period. A waste product called creatinine is processed in the kidney and eliminated through the urine. When the urine albumin-to-creatinine ratio exceeds 30 mg/g, it is regarded as abnormal by healthcare professionals.
How can I tell whether my urine contains protein?
you can undergo a straightforward urine test. This is a standard exam component. You would be asked to urinate into a “specimen cup,” which is a clean cup. Two teaspoons or less of your pee is all that is required for the test. A dipstick, a tiny plastic strip inserted in the urine, is used to do an immediate test on some of the pee. The remainder is under a microscope and submitted to a lab for an ACR (heparin ratio) test. If you have protein in your urine, an ACR will indicate it. Less than 30 mg/g of albumin is considered normal in urine. anything more than 30
What’s wrong if my urine contains a protein called albumin?
Your kidneys’ primary function is to filter the blood. Important substances like protein that your body requires are kept in your blood by your kidneys. They also eliminate waste and surplus water from your body, both of which are unnecessary.
You should contain little, if any, protein is your urine if your kidneys are functioning properly. However, if your kidneys are compromised, protein may “leak” into your urine.
How may albuminuria be diminished?
Taking ACE inhibitors or ARBs, which lower blood pressure, may help you lessen the quantity of protein in your urine. These drugs have names that finish in -april or -sartan.
Working with a certified dietitian who can assist you with meal planning and behavior adjustment may also help you protect your kidney and lower albuminuria. You may benefit from the food plan.
- If you are overweight, lose weight.
- avoid salty or sodium-rich meals.
- eat the proper kinds and quantities of protein.
Does albuminuria indicate renal disease if I have it?
e renal disease if I have it?Your doctor will perform more testing to rule out other possible causes of albuminuria, such as dehydration, before concluding that it is an indication of kidney disease in its early stages. The albumin test will be redone if your doctor has any reason to believe you have renal disease. Kidney disease can be detected by three positive outcomes over six months or longer.
A quick blood test will also be performed on you to determine your GFR. Glomerular filtration rate is known as GFR. Your GFR value can be used to assess well how your kidneys function.
You might also receive:
imaging exams (A CT scan or ultrasound). This creates an image of your urinary system and kidneys. It can reveal whether you have kidney problems or even other issues with your kidneys.
A renal biopsy This can assist determine what triggered your kidney illness and the extent of kidney damage.
Research on numerous illnesses and ailments is conducted and supported by the Central Institute of Health’s (NIH) Institute of the Digestive and Kidney Disorders (NIDDK) and other NIH divisions.
Are clinical trials suitable for you and what are they?
The foundation of all medical advancements is clinical research, which includes clinical trials. Clinical trials examine novel approaches to avert, diagnose, or cure illness. Clinical trials are also used by researchers to examine various facets of treatment, including improving the life quality for those with chronic diseases.
Do I need to get treated if I have albuminuria?
How frequently should I get tested for proteinuria (albuminuria)?
A healthcare professional should do this test as a routine check on those who are more likely to develop renal disease. Those at higher risk consist of:
- those who have diabetes
- High blood pressure sufferers
- people having a history of renal failure in their families
- those who are at least 65 years old
- certain ethnicity
Do I need to get treated if I have albuminuria?
If disease is identified, your doctor will come up with a treatment strategy. You can also be instructed to visit a nephrologist, a type of kidney specialist. Your therapy can consist of:
- alterations to your diet
- Lifestyle adjustments like quitting smoking, exercising, and losing excess weight
