What is the normal pH of urine?

The article was consulted professionally by Associate Professor, PhD, Dr. Le Ngoc Hung – Head of Laboratory Department – Micropsynian – Laboratory Department – Share99 Central Park International Hospital.

Urine is a eptic fluid produced by the kidneys and discharged out of the body through the urethra. Urine has many ingredients such as water, salt and substances dissolved from metabolism.

The urine test will have a pH specification that shows the balance of compounds in the urine that affect acidity levels. urine pH is a test that analyzes the acidity or alkalinity of urine.

1. What is the normal pH of urine?

The pH will assess the acidity of urine through the free H+ ion concentration in the urine, the normal urine pH is about 6.0 but can still range between 4.5-8.0 with normal health conditions. If this index falls below 5.0, the urine is acidized and higher than 8.0 is alkalized urine.

2. What urine pH indicators mean beyond normal

Kidney stones are small volumes of minerals that can accumulate in the kidneys causing pain when preventing urine from falling from the kidneys into the ureter. Kidney stones tend to be easy to establish when urine is too acidic or too alkaline. Your doctor surveys your urine pH to see if you are at risk of kidney stones.

Urine pH helps diagnose a number of abnormal diseases

One of the factors that greatly affects the pH of urine is food, so abnormal urine pH can also be the result of people being tested for overeing foods as follows

Acidic foods: Wheat, fish, soda, protein-rich foods or sugary foods.

Alkaline foods: Dried nuts, vegetables and the majority of fruits.

In addition, abnormal urine pH is also the result of a number of conditions. If urine pH is higher than 8.0 patients may be suffering from a number of diseases such as:

  • Kidney stones
  • Urinary tract infections
  • Renal dysfunction such as renal tubular acidosis, chronic renal failure
  • Alkali conversion due to vomiting
  • Respiratory alkalinity due to increased ventilation, abnormal rapid breathing
  • Gastric rotting
  • Obstruction of the position
  • Vomiting a lot

If urine pH is below 5.0, more acidic urine usually signals the following conditions:

  • Metabolic acidosis
  • Diabetes ketoacidosis
  • Diarrhea or severe undernutritriy
  • Dehydration
  • Not due to the disease but to the side effects of some drugs.

3. How urine is taken and what factors impact the urine pH test

To get urine properly it should be done as follows:

  • Before conducting urine sampling it is necessary to clean the genital area
  • After that, urinate normally and use a ileant vial to drain the urine
  • Urine must be taken in the middle of the line, i.e. do not take at the beginning of urination, and at the end, the amount of urine needs to reach 30-60ml to be eligible for pH testing.

Factors affecting test results:

  • Urine samples left long before being taken for testing can cause bacteria to increase the decomposition of ure to form NH3 causing urine alkalization (increased pH)
  • Ammonium chloride salt causes urine acidification
  • Sodium bicarbonate, potassium citrate and acetazolamide cause urine alkalization (increased pH)
  • Some medications can alter urine. Your doctor will recommend stopping before trying urine pH
  • Urine is alkaline after eating due to the excretion of stomach acid.
