ZINC (RBC) , BLOOD

The ZINC (RBC), BLOOD test measures zinc concentration within red blood cells (erythrocytes) to provide a more stable indicator of long-term zinc status and tissue stores than serum zinc. By assessing intracellular zinc, the assay reduces short-term variability caused by recent meals or acute-phase reactions and offers clinicians a clearer picture of chronic micronutrient status. The sample is collected as whole blood into an anticoagulant tube and analysed by a certified laboratory using trace‑element–sensitive techniques.

This test is recommended for evaluating suspected zinc deficiency, monitoring patients with malabsorption, chronic liver or kidney disease, those who have undergone bariatric surgery, or individuals on prolonged parenteral nutrition. Results support evidence‑based decisions on dietary counselling and supplementation; interpretation should always be combined with clinical assessment and other laboratory findings by a healthcare professional in Dubai or elsewhere in the UAE.
