What it measures
Zinc is a mineral that helps your immune system fight germs, helps wounds heal and supports your senses of taste and smell. This shows how much zinc is in your blood.
Why it matters for women
Your body needs more zinc during pregnancy and breastfeeding. Low zinc can be more common if you eat little or no meat or seafood, have a gut condition like Crohn’s disease, or have had weight-loss surgery. Zinc and copper compete in the body, so very high zinc can lower copper.
You might check it if…
- you eat little or no meat or seafood
- you get sick often or wounds heal slowly
- you’ve noticed changes in your taste or smell
- you’ve had weight-loss surgery or a gut condition like Crohn’s
What your result may mean
High Zinc: what it may mean
High zinc may mean supplement use, including lozenges and cold remedies, and long-term high intake can interfere with copper absorption. Very high zinc can lower copper enough to cause anemia or nerve problems. Too much zinc can cause nausea, vomiting or stomach cramps, and some people may have no symptoms. Zinc denture creams can add to the total. A sample can also read falsely high if red cells break open or the tube isn't made for trace metals, so a clinician may repeat it and check copper.
Low Zinc: what it may mean
Low zinc may affect immune function, wound healing, taste and skin health. It can happen with vegetarian or vegan diets, malabsorption, Crohn's disease or weight-loss surgery. Zinc needs can rise during pregnancy and breastfeeding, and long-term birth control pills can lower zinc a little. Some people may notice more infections, slow-healing cuts, hair loss or a dulled sense of taste. Illness, inflammation and time of day can also lower plasma zinc, so the timing of the draw can matter.
