Urine protein (UP, PRO)
Proteins are complex natural macromolecules. They are engaged in all processes occurring in the body and are vital for cellular functions and the formation of cells. Enzymes, biological catalysts, consist of proteins accelerating all biochemical processes in the body.
A urinalysis that includes a protein test is extensively used for diagnostic purposes and may be a sign of a renal disorder.
An abnormal amount of protein in the urine is called proteinuria.
Normally, healthy adults have no detectable protein in their urine. Small amounts of protein may also be found in healthy adults and may not be indicative of a disease.
Such proteinuria may be due to the eating whole protein-rich foods (raw eggs, milk, etc.), strenuous physical activity, exposure to cold, nervous tension. Mild proteinuria may be caused by an elevated body temperature.
Proteinuria may be seen in newborn babies in the first days of life. Even overfeeding a baby may cause protein in the baby’s urine. Such proteinuria is temporary and requires no treatment.
Protein may be found in the urine due to menstrual blood or vaginal discharge mixed in with the urine.
Protein in the urine may be an indicator of renal disorders, mostly glomerulonephritis, or an inflammatory process in the kidneys and urinary tract.
Protein found in the urine in early pregnancy may be a symptom of an undiagnosed renal disorder developed by the woman before the pregnancy. If so, medical supervision is needed.
Protein in the urine during pregnancy may be an incidental finding in one of the tests. You need to consult your doctor if protein has been detected in your urine repeatedly.
