What this test is
This test quantifies the concentration of zinc, an essential mineral involved in immune function, wound healing, and enzyme activity. It is used to evaluate suspected deficiencies or excesses, though blood zinc levels do not always perfectly reflect total body stores.
What it measures
- Zinc — reflects the amount of zinc circulating in the blood at the time of collection
What the test involves
A healthcare professional collects a small sample of blood, typically from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if you have symptoms suggesting a zinc deficiency, such as poor wound healing or frequent infections, or if you have conditions that affect nutrient absorption. It can also be used to monitor zinc levels in people receiving zinc supplementation or with certain chronic illnesses.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection laboratory. This may include fasting for a certain period or avoiding zinc-containing supplements beforehand.
How results are reported
Results are reported as a numerical value that your healthcare provider will interpret in the context of your health history. Reference ranges differ between laboratories, so the normal range on your report is specific to the lab that performed the test.
