Zinc - Fingerstick

This blood test measures the zinc level in the blood. Zinc is an essential mineral involved in many processes in the body, including the immune system, wound healing, cell division, and the health of the skin, hair, and nails.

This blood test is also supported by InsideTracker.

Why test for zinc?

A zinc test may be useful in cases of symptoms or conditions where a deficiency is suspected. Possible symptoms of a zinc deficiency include:

• weakened immune system;
• hair loss;
• skin problems or delayed wound healing;
• decreased appetite;
• a reduced sense of smell or taste;
• fatigue;
• growth retardation in children;
• In more severe cases, vision problems.

These symptoms are not specific to a zinc deficiency and may have other causes. A blood test can provide more insight into zinc status.

What does zinc do in the body?

Zinc is an essential trace element and plays a role in hundreds of enzymatic processes. Among other things, it is important for:

• normal functioning of the immune system;
• the formation and regeneration of body tissue;
• cell division and DNA and protein synthesis;
• the health of skin, hair, and nails;
• wound healing;
• the metabolism of carbohydrates, fats, and proteins;
• normal fertility and reproduction;
• maintaining normal testosterone levels in the blood;
• normal vision.

What foods contain zinc?

Zinc is found in various foods. Good sources include meat, cheese, fish, shellfish, eggs, whole-grain products, legumes, and nuts.

Zinc from animal-based foods is generally absorbed more easily. Plant-based foods may contain relatively high levels of phytates, which can reduce the absorption of zinc in the intestine.

What does a low zinc level mean?

A low zinc level may be associated with, among other things, insufficient intake, reduced absorption from the intestine, or an increased need. Certain chronic conditions can also affect zinc status.

If the results are abnormal, it’s important to consider not only the zinc level but also symptoms, diet, any supplements, and other relevant blood test results.

Can zinc levels be too high?

Excessive zinc intake is usually caused by excessive use of zinc supplements and not by a normal diet. An acute excess can cause symptoms such as nausea, vomiting, abdominal pain, and diarrhea.

Long-term use of high doses of zinc can also reduce the absorption of copper. This can eventually lead to a copper deficiency, which may result in anemia and neurological symptoms, among other things.

Therefore, do not use high doses of zinc for an extended period without a valid reason or expert guidance.
