this test give result about protein escaping into the urine and to detect kidney damage
Sample
24-hour urin sample
methodes of protien measuring
protien is not normally found in the urine, and urine protein tests measure protein being excreted in the urine. There are several different kinds of urine protein tests.
1- A semi-quantitative protein may be performed as part of aurine analysis, generally on arondom urin sample.
2-The quantity of protein in a 24-hour urin sample will be measured and reported as the amount of protein excreted per 24 hours. Also, the amount of protein in a random urine sample may be measured along with creatinine and reported as the ratio of urine protein to creatinine .
Creatinine, a byproduct of muscle metabolism, is normally excreted into the urine at a constant rate. When both a urine creatinine and a random urine protein test are performed, the resulting protein/creatinine ratio approaches the accuracy of the 24-hour urine protein test. Since saving all of the urine for a 24-hour period can be cumbersome for adults and difficult for infants and children, a random urine protein to creatinine ratio is sometimes substituted for a 24-hour urine protein sample
The presence of albumin in the urine
Albuminuria
has been shown to be a sensitive indicator of kidney diseas in patients with diabetes and with hypertension. Therefore, in some situations the doctor may test specifically for albumin in the urine, as opposed to total urine protein
increasing amounts of protein over time indicate increasing damage and decreasing kidney function.
protienuria is associated with many diseases
Amyloidosis, Bladder cancer, Drug therapies that are potentially toxic to the kidneys, Glomerulonephriti, Goodpasture’s syndrome and Kidney infection.
