Zinc, Serum Test
Zinc, Serum Test
Zinc is an essential trace element required for various biological processes, including immune function, wound healing, enzyme activity, and DNA synthesis. The Serum Zinc Test measures the level of zinc in the blood to assess nutritional status, immune function, and metabolic disorders.
Zinc deficiency can lead to impaired immunity, slow wound healing, hair loss, and developmental delays, while excessive zinc levels can cause nausea, dizziness, and immune suppression. This test helps detect deficiency, toxicity, or underlying metabolic disorders affecting zinc absorption or utilization.
What is the Zinc, Serum Test Used For?
- Diagnosing zinc deficiency in individuals with malnutrition or absorption disorders.
- Monitoring zinc levels in individuals on long-term supplementation.
- Assessing patients with unexplained immune dysfunction or slow wound healing.
- Evaluating individuals with growth retardation or developmental delays.
- Checking for zinc toxicity due to excessive supplementation.
Symptoms Indicating the Need for the Test
Frequent infections due to weakened immunity
Slow wound healing and skin rashes.
Loss of taste and smell.
Hair thinning or loss.
Delayed growth in children.
Nausea, vomiting, and diarrhea.
Dizziness and headaches.
Imbalance in copper levels, leading to anemia.
Preparation for the Test
Fasting is not required, but avoid zinc-containing supplements for 24 hours before the test. Inform your doctor about medications, multivitamins, or mineral supplements, as they may affect zinc levels. A blood sample is collected from a vein in your arm for analysis.

FAQs
What are the common causes of zinc deficiency?
Poor diet, malabsorption disorders (such as Crohn’s disease or celiac disease), chronic illnesses, and excessive alcohol consumption.
How is zinc deficiency treated?
By consuming zinc-rich foods (meat, seafood, nuts, and whole grains) or taking prescribed zinc supplements.
Can excess zinc intake be harmful?
Yes, excessive zinc can cause nausea, impair immune function, and interfere with copper absorption, leading to anemia.
How does zinc affect the immune system?
Zinc plays a key role in immune cell production, reducing inflammation and promoting faster recovery from infections.
Are there other tests related to zinc levels?
Serum Copper Test, Hair Zinc Analysis, and Metallothionein Tests may help assess overall mineral balance.
