Red Blood Cell Zinc

Overview

Red Blood Cell Zinc measures the amount of zinc inside your red blood cells, which are the cells responsible for carrying oxygen throughout your body. Zinc is an essential mineral that plays a crucial role in many bodily functions, including supporting your immune system, helping wounds heal, and aiding growth and development. By looking at the zinc levels within your red blood cells, we get a picture of your body's zinc status over the past few months, rather than just a momentary snapshot. Think of it as checking the balance of your savings account instead of just the cash in your wallet. This longer-term view helps us understand if you're getting enough zinc in your diet or if your body is absorbing and using it properly.

Testing Levels:

• High (14 µmol/L) - If your Red Blood Cell Zinc levels are higher than normal, it might mean you're taking in too much zinc, possibly from overusing supplements. Too much zinc can cause symptoms like nausea and headaches, and it can make it harder for your body to absorb other important minerals like copper and iron. It's important to check your zinc intake and adjust it to avoid these issues.
  
  
• Mid - Having Red Blood Cell Zinc levels within the normal range means your body has the right amount of zinc to support its many functions. It shows that you're getting enough zinc from your diet and that your body is absorbing and using it properly. This balance is a good sign of overall health.
  
  If your levels are nearing the upper limit, it suggests your zinc levels are on the higher side. This could be due to a diet high in zinc or from supplements. While it's not necessarily harmful yet, it's a good idea to keep an eye on how much zinc you're consuming to prevent any potential problems.
  
  If your levels are close to the lower limit, it might be a hint that you're not getting quite enough zinc or that your body isn't absorbing it as well as it could. While you're not deficient yet, you might want to look at your diet to make sure you're eating enough zinc-rich foods.
  
  
• Low (9 µmol/L) - Low Red Blood Cell Zinc levels indicate a zinc deficiency. This can lead to issues like getting sick more often, slow healing of wounds, loss of appetite, and changes in taste. It's important to find out why your zinc is low - whether it's not eating enough zinc-rich foods, problems with absorption, or increased loss - and take steps to improve it.

Why We Test Red Blood Cell Zinc

Testing Red Blood Cell Zinc offers a more accurate picture of your body's zinc status over time compared to standard blood tests. It can help identify if you're low or high in zinc, which is important because both too little and too much zinc can affect your health. Knowing your levels can guide you in adjusting your diet or supplements to support your well-being.

What Affects It

Several factors can influence Red Blood Cell Zinc levels. Your diet is a major one - if you're not eating enough foods rich in zinc, your levels might be low. Conditions that affect digestion, like Crohn's disease or coeliac disease, can make it harder for your body to absorb zinc. High levels of physical stress, infections, or inflammation can also impact zinc levels. Additionally, drinking too much alcohol and certain medications can interfere with how your body handles zinc.

How to Improve

If your Red Blood Cell Zinc levels are high or nearing high, you should consider reducing zinc supplements or high-zinc foods to prevent potential problems. If your levels are low or close to low, increasing foods rich in zinc - like meat, shellfish, legumes, nuts, and seeds - can help boost your levels. In some cases, a zinc supplement might be recommended. It's also important to address any issues that might be affecting absorption by consulting with a healthcare professional.
