Vitamin C (Ascorbic Acid)

Includes 1 test

Vitamin C measurement is used to control subvitaminosis and to monitor supplement therapy.

Vitamin C (ascorbic acid) is a water-soluble vitamin found in citrus fruits and leafy vegetables and tomatoes. Food intake of vitamin C is absorbed by the small intestine and stored in the adrenals, kidneys, spleen, liver and white blood cells. Excess vitamin C is excreted in the urine. Vitamin C is important in maintaining cellular structures, in collagen synthesis, in maintaining capillary integrity, in wound healing, in the absorption of iron from the gut and in resistance to infections.

Humans, unlike most animals, are unable to synthesize vitamin C endogenously and are therefore an essential component of the diet. Vitamin C is required for the synthesis of neuropeptides, the production of adrenal steroid hormones, the promotion of the conversion of trocollagen to collagen, and the metabolism of tyrosine and folic acid. It also plays a role in the metabolism of lipids and vitamins and is a powerful antioxidant. Specific antioxidant effects of Vitamin C include, inter alia: activating liver detoxification enzymes, blocking and destroying free radicals, preserving and restoring the antioxidant potential of vitamin E, and preventing the formation of carotenoids.

Smoking reduces vitamin C levels. Inadequate vitamin C intake results in scurvy development in about 90 days. Scurvy is characterized by the inability to form sufficient intercellular substance in the connective tissues, which results in the formation of swollen, ulcerative lesions in the gums, mouth and other tissues. Early symptoms can include weakness and easy fatigue as well as difficulty breathing and pain in the joints, bones and muscles.

The need for vitamin C is increased in patients who regularly use aspirin, contraceptives, tetracycline and various other medications. Stress and advanced age also increase the need for vitamin C.

Possible Interpretations of Pathological Values
  • Increase: Excessive intake of vitamin C supplements and medications
  • Decrease: Alcoholism, hyperthyroidism, malabsorption, pregnancy, kidney failure, scurvy, smokers




Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
