Selenium
Selenium is an essential trace mineral needed for a healthy
immune system and proper thyroid hormone production. It also
helps recycle vitamins C and E into their active forms, boosting
their antioxidant effects.
This test measures the level of selenium in your blood to assess
whether you have too little or too much. It can help identify
imbalances that may affect immune function, antioxidant
protection, or thyroid health.
When to use this test:
● To check for deficiency or potential toxicity.
● In cases of unknown causes of thyroid or fertility problems.

Oxidative Stress Markers
Oxidative stress testing helps determine if the body is
overwhelmed by free radicals by measuring markers like 8-OHdG
(which indicates DNA damage) or checking antioxidant levels,
such as glutathione. Some tests also assess the overall balance
between free radicals and antioxidants to evaluate how well the
body is managing oxidative stress.
When combined with a physical exam, health history, and current
symptoms, these test results can provide valuable insights into
possible root causes of health concerns. Based on the findings,
additional testing may be recommended4such as gut
microbiome analysis, screenings for related conditions, or genetic
testing to uncover contributing factors.
