Zinc (Blood Test)

A zinc blood test measures the level of zinc in the blood, which is an essential mineral that is important for normal growth and development, immune function, wound healing, and many other processes in the body.

Low levels of zinc can lead to symptoms such as slow wound healing, hair loss, poor immune function, and impaired growth in children. On the other hand, high levels of zinc can lead to symptoms such as nausea, vomiting, and diarrhea.

A zinc blood test can help diagnose zinc deficiency or excess, and may be ordered if a person is showing signs and symptoms of a zinc deficiency or excess, or if they have a condition that affects zinc absorption or metabolism. The test is usually done by taking a sample of blood from a vein in the arm and sending it to a laboratory for analysis.

It is important to follow any instructions provided before having a zinc blood test, such as fasting for a certain amount of time before the test.
