Selenium RBC (Red Blood Cell) testing is a blood test that measures the level of selenium in the red blood cells. Here are some reasons why you may want to consider getting tested for Selenium RBC:
Selenium Deficiency: Selenium is an essential trace mineral that is important for many bodily functions, including thyroid function, immune system function, and antioxidant activity. A deficiency in selenium can lead to various health problems, including muscle weakness, fatigue, and a weakened immune system.
Monitoring Selenium Status: If you are taking selenium supplements or have a diet that is high in selenium, your healthcare provider may recommend monitoring your Selenium RBC levels to ensure that you are not getting too much selenium, which can also lead to health problems.
Certain Medical Conditions: Selenium deficiency has been linked to several medical conditions, including autoimmune thyroiditis, certain types of cancer, and Keshan disease, which is a type of heart disease. Selenium RBC testing may be used to help diagnose or monitor these conditions.
Environmental Exposure: Selenium levels in the body can be influenced by environmental factors, including exposure to toxic substances such as mercury or cadmium. Selenium RBC testing may be used to assess exposure to these substances.
It’s important to note that the normal range for Selenium RBC levels can vary depending on factors such as age, gender, and geographic location. Your healthcare provider can help you interpret your test results and determine if any further action is needed.
