A urine pH test is a test that analyzes the acidity or alkalinity of a urine sample.
Kidney stones are small masses of minerals that can collect in the kidneys and cause pain as they prevent urine from passing through your kidneys and urinary system. Since these stones tend to form in a highly acidic or basic/alkaline environment, your doctor may test your urine to determine the likelihood you will form kidney stones.
Certain medications can make your urine more acidic. Your physician may order the urine pH level test to determine whether your medications are making your urine too acidic.
The urine pH level test can also determine the best medication to prescribe when you have a urinary tract infection.
After you provide a urine sample, it is tested right away. The health care provider uses a dipstick made with a color-sensitive pad. The color change on the dipstick tells the provider the level of acid in your urine.
A neutral pH is 7.0. The higher the number, the more basic (alkaline) it is. The lower the number, the more acidic your urine is. The average urine sample tests at about 6.0.
If your urine sample is lower, this could indicate an environment conducive to kidney stones.
