Cysteine
Explanation: Cysteine is an amino acid, a building block of proteins. It is considered a semi-essential amino acid, meaning human body can make some of it, but needs extra from foods like eggs, meat, and some grains. Cysteine helps build proteins, supports antioxidant defenses, and plays a role in detoxification.
Test purpose: A cysteine blood test helps assess:
- Nutritional status, particularly in people with malabsorption disorders or protein deficiencies.
- Oxidative stress and antioxidant balance, since cysteine is essential for glutathione production.
