Sodium in Urine

Sodium is an essential electrolyte vital for the proper functioning of the body, particularly the nervous system and muscles. It works alongside other electrolytes like chloride, potassium, and bicarbonate to regulate the body’s fluid balance. The sodium in urine test, available at IntroLab in Belgrade, is an important diagnostic tool that can help diagnose and monitor various conditions affecting sodium levels.

What is the purpose of the sodium in urine test?

This urine test helps diagnose and monitor various disorders that affect the body’s acid-base balance and fluid regulation. These disorders can lead to either low or high sodium levels. The test is typically conducted for:

• Individuals with symptoms of dehydration caused by diarrhea, vomiting, excessive sweating, or frequent urination
• Individuals with symptoms of fluid overload, such as significant swelling due to heart, liver, or kidney disease
• Patients with blood pressure problems.

How is the test performed?

The test requires a urine sample. Typically, the sample is collected in the morning, and no special preparation is needed. Results are usually available within one day.

Elevated sodium levels

Elevated sodium levels in urine, known as hypernatriuria, can be associated with several conditions, including:

• Dehydration
• Kidney disorders
• Use of certain medications (diuretics and corticosteroids)

Low sodium levels

Low sodium levels in urine can be linked to:

• Sodium deficiency in the diet
• Adrenal gland disorders (Addison’s disease)
• Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
