Urine Test Could Predict Life Expectancy

Urine that has been used as a health indicator could help predict a person's life expectancy. A report from the National Kidney Foundation's American Journal of Kidney Diseases, shows a strong correlation between the level of protein in the urine (proteinuria) with the risk of death.

Based on these reports, healthy people tend to have low levels of proteinuria. This signals the kidneys to function properly, the organs that filter out the protein to remain in the body. Proteins that go wasted indicate a specific defect that causes the kidneys to leak.

"Our report shows, high proteinuria can reduce life expectancy in the majority of men and women," says researcher Dr. Tanvir Chowdhury Turin of the University of Calgary. This study used 810 thousand urine samples of patients who are not hospitalized in Alberta, Canada. The patient also had no history of renal disease associated with.

The results showed moderate to high levels of proteinuria lower life expectancy 30-85 years of age in men and women. Men and women age 40 years without proteinuria have a life expectancy of 15.2 and 17.4 years longer, than those with higher levels of proteinuria. Women and men without proteinuria also have a life expectancy of 8.2 and 10.5 years longer, than those with moderate levels of proteinuria.

Testing usually use dipstick proteinuria and can be done in any laboratory. In healthy conditions, proteinuria usually still be found in small quantities. Moderate to large amount of proteinuria indicates an error in the filtering system (glomeruli) or wound in the kidney area. This condition can be symptoms of glomerulonephritis. Infection in the urine such as cystitis or pyelonephritis also cause high levels of proteinuria.

In healthy conditions, a person can spend proteinuria ranging from 0-8 mg / dL. Normally a small amount of protein that passes into the renal re-absorbed by the body. This may be because the kidneys also control the amount of protein in the blood. When a protein in the blood is too high then the protein escaped and joined the urine. The magnitude of the exit marked proteinuria foamy urine (foamy).

The greater proteinuria was out, the higher the number on the dipstick marker (marker level urine). Figures 1 + proteinuria cater for as many as 30 mg / dL or the equivalent of less than 0.5 g / day. Figures 2 + proteinuria indicate that came out was 100 mg / dL or the equivalent of 0.5 to 1 g / day. Figures 3 + proteinuria is for the exit of 300 mg / dL or less the equivalent of 1-2 g / day. The highest score 4 + is intended for proteinuria more than 200 mg / dL or the equivalent of more than 2 g / day.

Previously only known link between the level of proteinuria with early onset of symptoms associated with kidney disease. Given this research, it allows one to know the immediate risk to his life, and plan for the recovery from the outset.
