Zinc, Serum Concentration (Mass Concentration)

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like frequent infections, hair loss, slow wound healing, or fatigue. It may also be done as part of a general health check or if you have conditions like diabetes, liver disease, or kidney problems that can affect zinc absorption or metabolism.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for a few hours before the blood draw if your provider specifies it. Bring any medications you’re currently taking to your appointment.

What the Results Mean

Results are compared to standard reference ranges for healthy adults. While exact values vary by lab, low zinc levels may signal dietary deficiencies or health issues requiring further evaluation, while very high levels could indicate conditions like acute pancreatitis or certain metabolic disorders.

Common Causes of Low or High Zinc Levels

Low zinc levels can result from poor diet, gastrointestinal disorders (like Crohn’s disease), chronic illnesses, or certain medications. High levels may be linked to liver disease, kidney failure, or rare genetic disorders.
