The normal urine pH range is between 4.5 and 8. A urine pH test is carried out as part of a urinalysis, which helps doctors diagnose various diseases. The pH of urine can vary depending on factors such as diet, medications, and underlying medical conditions. A urine pH of 8.5–9 may indicate a urinary tract infection (UTI). The formation of different types of kidney stones is strongly influenced by urinary pH.
Factors Affecting Urine pH:
- Diet: Eating a diet high in animal protein or acidic foods can lower urine pH, making it more acidic. Conversely, a diet rich in fruits and vegetables can increase urine pH, making it more alkaline.
- Medications: Some medications, such as diuretics and antacids, can affect urine pH.
- Medical Conditions: Certain medical conditions, such as kidney failure, diabetes, and urinary tract infections, can alter urine pH.
Interpreting Urine pH Results:
- Acidic urine (pH below 6): This may indicate conditions such as metabolic acidosis, dehydration, or a high-protein diet.
- Alkaline urine (pH above 8): This may indicate conditions such as urinary tract infections, kidney failure, or a high-vegetable diet.
Key Takeaways:
- Urine pH is a measure of the acidity or alkalinity of urine.
- The normal urine pH range is between 4.5 and 8.
- Urine pH can be influenced by diet, medications, and underlying medical conditions.
- A urine pH test can help doctors diagnose various diseases.
