Potassium, 24H Urine

This test measures the levels of potassium excreted in your urine over a 24-hour period. Potassium is vital for muscle contraction, nerve function, and maintaining fluid balance. Abnormal levels can indicate kidney diseases, hormonal imbalances, or nutritional deficiencies.

This test is done to:

• Assess kidney function
• Evaluate electrolyte balance
• Diagnose conditions affecting potassium levels
• Monitor treatment effectiveness for specific diseases
• Identify potential causes of abnormal heart rhythms

This test is recommended for patients with:

• Known or suspected kidney disease
• Heart rhythm abnormalities
• High blood pressure
• Symptoms of electrolyte imbalance (muscle weakness, fatigue)
• Diseases affecting potassium levels

• Normal range typically between 25 - 125 mmol/day
• Abnormal levels may indicate kidney issues, hormone imbalances, or dietary concerns

Consult your doctor for interpretation and further investigations

During this test:

• You will collect all urine over 24 hours
• Keep urine refrigerated
• Lab will analyse potassium levels using ISE method

• Avoid bananas, tea, coffee, and cold drinks.
• Provide accurate urine volume collected info to lab.
• Inform lab about any recent medications or health conditions.
• Reach out to your healthcare provider for any specific requirements.

Other tests alongside might include:

• Sodium Testing: To measure sodium levels for electrolyte balance evaluation
• Creatinine Testing: To assess kidney function through waste product levels in blood
• Urine Protein Test: To detect protein presence linked to kidney disease

24-hour urine potassium test

Hypokalemia refers to low blood potassium levels, often due to excessive loss from urine or vomiting. Hyperkalemia indicates high blood potassium levels and can be caused by kidney dysfunction or certain medications.
