[The population study of total antioxidant activity of human blood serum and urine]
Abstract:
Many diseases are accompanied with the development of oxidation stress. The analysis of total antioxidant activity is one of the techniques to assess the oxidation-reduction balance. In spite of availability of normative documents recommending to apply this examination the antioxidant activity analysis technique is used in practice not very often. The absence of reference values of this indicator is one of the reasons of this situation. The article presents the results of the study of total antioxidant activity of human blood serum and single portion of urine. On the basis of the results the reference limits were estimated. The correlation analysis of interrelationship between antioxidant activity analysis technique assessment and age, gender and content of substances mostly inputting into analysis results.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
