Micronutrient, Selenium, Blood
Quest Diagnostics
Sample type: Whole blood
Requires fasting: No
Phlebotomy required
Details
Selenium (SE) is a key component of a number of functional selenoproteins required for normal health. The best known of these are the antioxidant glutathione peroxidase enzymes, which remove hydrogen and damaging lipid and phospholipid hydroperoxides generated in vivo by free radicals and other oxygen-derived species. If not removed, lipid hydroperoxides impair membrane structure and function and cause blood-clotting disturbances by decreasing the production of prostacyclin while increasing the production of thromboxane.

Estimated days for results: Results should be available in 2 - 5 business days after the sample is collected
Selenium is crucial for our body, acting as a building block for important proteins called selenoproteins. These proteins, including powerful antioxidants like glutathione peroxidase, protect our cells from damage by removing harmful substances produced by our body. Without selenium, our cells could be damaged, leading to problems with blood clotting and cell membrane integrity by affecting substances that control blood clotting.
