Measures zinc levels in the blood.
Zinc is essential to wound healing, immune function, cell growth and reproduction and overall bodily function. Low levels of zinc can see all of the aforementioned areas suffer where too much zinc can cause zinc poisoning. High zinc levels are not extremely common; low levels are far more common and can often be corrected by simple changes to diet.
High levels of zinc can be fatal and can be caused by overexposure to products that contain zinc, such as certain metals, household cleaners, paints and rust removers and related items. Excess zinc supplementation can also be problematic. Brain damage and organ failure are both possible with prolonged high zinc levels.
Low zinc levels are far more common and have been linked to poor zinc absorption. Low levels may promote hypogonadism (low testosterone), a weakened immune system, impotence and skin and eye lesions. Zinc deficiency has been referred to as an epidemic in some medical circles.
