5. Kidney Function Test:

   • Purpose: To evaluate kidney function.
   • Why Is It Ordered: Kidney disorders can affect the balance of trace elements, including zinc.

6. 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.

7. 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.

8. Magnesium:

   • 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.
