This test is used to evaluate deficiencies in zinc since the body does not store this important mineral. Levels may be low in fever, sepsis, estrogen therapy, stress, or heart disease. Zinc deficiencies may result in abnormal development, poor immune function, and hormone imbalances. Additionally, people with low levels of zinc often report altered taste and smell, impaired night vision, and emotional instability.
Fasting is not required for this test. Take all medications as prescribed.
