Enzyme Function: Zinc is a cofactor for many enzymes involved in various metabolic reactions, including DNA synthesis, protein synthesis, and carbohydrate metabolism.
Other Lab Tests Ordered Alongside a Zinc Test
When zinc levels are tested, it's often as part of an assessment of nutritional status, immune function, or to investigate symptoms related to zinc imbalance. Alongside a Zinc test, several other tests may be ordered to provide a comprehensive evaluation:
Copper and Ceruloplasmin:
- Purpose: Copper levels and ceruloplasmin (a protein that binds copper) are often tested alongside zinc as these trace elements are often interrelated.
- Why Is It Ordered: To assess for copper deficiency or Wilson’s disease (a condition of copper overload), which can sometimes present with similar symptoms to zinc deficiency or affect zinc metabolism.
Complete Blood Count (CBC):
- Purpose: To provide a broad picture of overall health, including red and white blood cells and platelets.
- Why Is It Ordered: Zinc deficiency can affect blood cell production, leading to conditions such as anemia or changes in white blood cell count.
- Purpose: To assess iron status in the body.
- Why Is It Ordered: Zinc plays a role in iron metabolism, and iron deficiency anemia can sometimes coexist with or mimic symptoms of zinc deficiency.
- Purpose: Albumin is a protein in the blood that can affect or be affected by zinc levels.
- Why Is It Ordered: Low albumin levels can lead to low zinc levels, and vice versa; assessing albumin can help interpret zinc levels, especially in cases of malnutrition or liver disease.
Kidney Function Test:
- Purpose: To evaluate kidney function.
- Why Is It Ordered: Kidney disorders can affect the balance of trace elements, including zinc.
Alkaline Phosphatase (ALP):
- Purpose: ALP is an enzyme related to the liver, bones, and other tissues, and its activity is partly dependent on zinc.
- Why Is It Ordered: Low zinc levels can lead to decreased ALP activity, and assessing ALP can provide additional insights into liver and bone health.
Vitamin D Levels:
- Purpose: To measure the level of Vitamin D, which is important for bone health and immune function.
- Why Is It Ordered: Vitamin D status can influence overall health and is often assessed as part of a nutritional status evaluation.
- Purpose: Magnesium, like zinc, is a vital mineral and is involved in numerous enzymatic reactions.
- Why Is It Ordered: To assess for magnesium deficiency, which can occur alongside or independently of zinc deficiency.
These tests, when ordered alongside a Zinc test, provide a comprehensive view of an individual’s nutritional status, trace element balance, and overall health. They can help diagnose the cause of symptoms related to zinc imbalance, such as impaired immune function, slow wound healing, and unusual growth patterns. The specific tests selected depend on the individual's medical history, current symptoms, and the purpose of the zinc testing.
