Why is the 24-Hour Urine Zinc Test Important?

Zinc deficiency or excess can significantly impact overall health. The 24-hour urine zinc analysis helps in diagnosing and monitoring conditions such as:

1. Chronic zinc deficiency

2. Malabsorption syndromes

3. Kidney and liver disorders

4. Wilson’s disease and other metabolic conditions

5. Chronic diarrhea or gastrointestinal diseases

6. Excessive zinc supplementation toxicity

This test is often recommended when long-term zinc imbalance is suspected or when monitoring treatment effectiveness.
