Vitamin C

The vitamin C test measures the levels of vitamin C (ascorbic acid) in the blood. Vitamin C is a powerful antioxidant essential for the immune system, skin health, and the body’s ability to repair tissues. It also plays a key role in collagen production, iron absorption, and overall protection against oxidative stress. Vitamin C is crucial for maintaining a strong immune response, healing wounds, and supporting skin health. A deficiency in vitamin C can lead to issues such as weakened immunity, fatigue, joint pain, and in severe cases, scurvy. Testing helps determine whether your body has adequate levels of this essential nutrient. Indications for testing - Frequent infections or weakened immune system - Poor wound healing or skin issues - Chronic fatigue or general malaise - Bleeding gums or oral health issues - Suspected scurvy or vitamin C deficiency due to malnutrition - People on restrictive diets or with gastrointestinal conditions affecting nutrient absorption What can be detected - Vitamin C deficiency: Low levels can indicate a lack of this important nutrient, leading to potential health issues such as scurvy, immune dysfunction, and skin problems. - Antioxidant status: Vitamin C levels also reflect your body’s ability to fight oxidative stress, which can impact inflammation and aging. How to prepare for the test Preparation for a vitamin C test is usually minimal. Fasting is not typically required, but it’s recommended to avoid taking vitamin C supplements for 24 hours before the test to prevent artificially elevated results. Follow your healthcare provider’s instructions for the most accurate outcome.
