Zinc, Serum / Plasma Test Overview
Zinc is an important mineral for human health, and it supports various immune functions and protein production in the body. The zinc serum test is used by doctors to determine the level of zinc in your blood and accordingly assess whether you have any zinc deficiency or not. Based on the results of the zinc serum plasma test, doctors can diagnose certain medical conditions and offer treatment for any zinc deficiency in the body. The zinc serum test is generally recommended in response to symptoms presented by doctors. In some cases, the zinc serum test is also recommended as a screening test to eliminate zinc deficiency as a cause of medical symptoms.
A zinc serum test is prescribed in response to symptoms presented by patients. The primary medical condition that’s diagnosed with the zinc serum plasma test is zinc deficiency or excessive zinc levels in the blood. Here are the symptoms that warrant doctors to prescribe a zinc serum test.
Slow wound healing
Loss of appetite
Weakness
Immune system compromise
These symptoms can be caused both by zinc deficiency or excess zinc levels. The real underlying cause can only be determined by the results of a zinc serum plasma test.
The normal range of a zinc serum test is between 66 to 106 mcg/dL. Any zinc serum plasma test result that’s below 70 mcg/dL in adult women and 74 mcg/dL in adult men can indicate zinc deficiency. In case of abnormal zinc levels, doctors will, in most cases, recommend a course of treatment to help correct the zinc level in the body.
The zinc serum test is performed as a simple blood test with a blood sample drawn from the veins in the patient’s forearm. There are some prerequisites that patients must follow before taking a zinc serum plasma test. This includes not having any seafood or freshwater fish for at least three days prior to the day of the test.
