RBC Zinc

What's 
RBC Zinc
?
Red Blood Cell (RBC) Zinc is a way to measure the amount of zinc in your red blood cells. Zinc is an important mineral that your body needs for many different functions. It helps with your immune system, making proteins, healing wounds, creating DNA, and dividing cells. Zinc is also important for growth and development during pregnancy, childhood, and teenage years. Since zinc is stored in different parts of your body, including red blood cells, the RBC Zinc test gives a more accurate picture of how much zinc you have over a longer time, compared to a regular blood test for zinc.
If Your Levels Are High
Having high levels of RBC Zinc means that your body might be taking in and storing more zinc than it usually needs. This can happen if you're consuming a lot of zinc-rich foods or taking supplements with high amounts of zinc. Some medications, like antacids, laxatives, and certain antibiotics, can also cause your body to absorb more zinc. In some cases, high RBC Zinc levels might be a sign of a health issue that affects how your body manages zinc, such as liver disease or hemolytic anemia. It's important to remember that while zinc is crucial for many body functions, having too much can throw off the balance of other essential minerals like copper and iron.
Symptoms of High Levels
Symptoms of high levels of RBC Zinc may include nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. In severe cases, it can lead to reduced immune function and altered sense of taste or smell.
If Your Levels are Low
Low RBC Zinc levels might mean that your body isn't getting enough of this important mineral, which plays a key role in many processes like supporting your immune system, building proteins, and helping cells divide. This could be due to not eating enough foods rich in zinc, having trouble absorbing zinc in your digestive system, or taking certain medications that can interfere with zinc absorption. Additionally, factors like ongoing stress, diabetes, or gut-related issues could also impact your body's zinc levels.
Symptoms of Low Levels
Symptoms of low levels of RBC Zinc may include a weakened immune system, slow wound healing, loss of appetite, taste or smell changes, and growth and development issues in children and adolescents.
