What is Protein Urine?
The Protein, Urine test is performed to screen for excessive proteins excreted in urine to help in monitoring kidney functioning. It also helps to determine any damage caused to the kidneys.
Why is Protein Urine done?
The Protein, Urine is done:
To monitor kidney functioning as a part of a routine checkup or as part of a follow-up to a previous positive urine protein test
To check for damage when the patient is suffering from a condition that affects the kidneys
To see if a kidney function is responding to the suggested treatment
If you have symptoms of a urinary tract infection (UTI)
What does Protein Urine Measure?
The Protein, Urine measures the excessive protein excreted in the urine. The urine protein tests measure the protein which is released into the urine. Normally, the urine protein elimination is less than 150 mg/day and less than 30 mg of albumin/day. Temporarily raised levels may be seen in conditions such as stress, infections, pregnancy, cold exposure, diet, or heavy exercise.
The appearance of persistent protein discharge in the urine suggests possible kidney damage or the requirement of additional tests to know the cause.
In a normal functioning kidney, the filtered proteins are retained or reabsorbed and sent back to the blood. Whereas, if any damage is caused to the kidneys then it may affect their functioning which may cause detectable amounts of protein extracted into the urine.
