Zinc Serum is a blood test that measures the level of zinc in the bloodstream. Zinc is an essential trace mineral important for immune function, wound healing, DNA synthesis, and cell division. Abnormal zinc levels can indicate deficiency or excess.

– Zinc deficiency can lead to symptoms such as impaired growth, hair loss, delayed wound healing, and weakened immune response.
– Excessive zinc levels can cause toxicity, leading to nausea, vomiting, and interference with copper absorption.

The test is commonly used to diagnose zinc deficiency, assess nutritional status, and evaluate conditions like malabsorption, chronic illnesses, or certain genetic disorders.
