The acid loading test (pH) measures the ability of the kidneys to send acid to the urine when there is too much acid in the blood VSports手机版. This test involves both a blood test and urine test.
How to Prepare for the Test
Your health care provider will tell you to take ammonium chloride capsules by mouth for 3 days before the test.
"VSports注册入口" How the Test will Feel
When the needle is inserted to draw blood, some people feel moderate pain VSports最新版本. Others feel only a prick or stinging. Afterward, there may be some throbbing or slight bruising. This soon goes away.
The urine test involves only normal urination, and there is no discomfort.
Why the Test is Performed (V体育ios版)
This test is done to see how well your kidneys control the body's acid-base balance.
"V体育安卓版" Normal Results
Urine with a pH less than 5.3 is normal.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples V体育官网入口. Talk to your provider about the meaning of your specific test results.

Risks (V体育官网)
