Uric acid is easily precipitated out of urine, which will affect the kidney function. If you find low pH value during physical examination, you should go for laboratory tests related to kidney system, such as kidney ultrasound and CT, to find out whether there are substantial lesions in kidney, and you should check the value of uric acid and other tests to exclude kidney diseases.
