Overview of the Vitamin C
The Vitamin C blood test measures circulating ascorbic acid, providing information about current Vitamin C status.
The test contains 1 biomarker: Vitamin C (active).
Vitamin C is a water-soluble vitamin and antioxidant required for normal collagen formation, wound healing, iron absorption and several enzymatic reactions.
Humans cannot manufacture Vitamin C and therefore depend on dietary intake.
Good sources include citrus fruit, berries, peppers, tomatoes and many vegetables.
Severe deficiency causes scurvy, although clinically significant deficiency usually develops gradually and is now uncommon in people eating a varied diet.
Risk is higher with highly restricted diets, severe food insecurity, malabsorption, alcohol dependence and some chronic illnesses.
Smoking is also associated with increased Vitamin C turnover and lower circulating levels.
Vitamin C is relatively unstable in blood specimens, which means appropriate sample handling is important for reliable analysis.
A result primarily reflects recent Vitamin C availability rather than long-term tissue stores.
What Does the Vitamin C Test Check?
This test measures 1 biomarker.
Vitamin C (active)
Measures circulating ascorbic acid to support assessment of current Vitamin C status and possible deficiency.
Who May Benefit From the Vitamin C Test?
Testing may be appropriate where dietary history or clinical features suggest inadequate Vitamin C.
People with very restricted fruit and vegetable intake - Vitamin C depends on regular dietary supply.
People with suspected malnutrition - Deficiency can accompany broader micronutrient inadequacy.
People with gastrointestinal malabsorption - Intestinal disease can reduce nutrient absorption.
People who smoke heavily - Smoking increases oxidative stress and Vitamin C requirements.
People with unexplained bruising or gum symptoms - Severe deficiency can impair collagen integrity.
People with poor wound healing and nutritional risk - Vitamin C is required for collagen synthesis.
People taking high-dose supplements - Testing may occasionally be useful when intake is substantial.
People with a previous low Vitamin C result - Repeat measurement can assess response to dietary correction.
How to Prepare
Choose a sample collection route capable of meeting the laboratory's handling requirements.
Do not stop clinically necessary supplements without appropriate advice.
Symptoms and Reasons to Consider the Vitamin C Test
Symptoms generally occur only when deficiency is significant.
Easy bruising - Impaired collagen integrity can increase capillary fragility.
Bleeding or swollen gums - Gingival changes are characteristic of more substantial deficiency.
Poor wound healing - Collagen synthesis requires Vitamin C.
Small red or purple skin spots - Petechiae can occur in severe deficiency.
Corkscrew-shaped body hairs - This is a recognised feature of scurvy.
Fatigue with substantial nutritional risk - Vitamin C deficiency may coexist with other deficiencies.
Joint or muscle discomfort in severe deficiency - Connective-tissue changes can contribute.
Very restricted dietary intake - Deficiency may be present before classic symptoms develop.
Bruising, bleeding and fatigue have many possible causes.
Unexplained significant bleeding or severe illness requires clinical assessment rather than assuming Vitamin C deficiency.

When Will I Receive My Results?
The current customer-facing turnaround for Vitamin C is approximately 8 days after your sample reaches the laboratory.
Vitamin C is a specialist nutritional assay and requires appropriate handling and processing.
The report is released once analysis, quality control and authorisation are complete.
An unsuitable or poorly preserved specimen may require recollection because Vitamin C can degrade after collection.
Understanding Your Results
A low result can support Vitamin C deficiency when dietary history and clinical circumstances are compatible.
The degree of reduction helps determine how clinically important the finding may be.
A normal result indicates adequate circulating Vitamin C at the time of collection.
Higher concentrations are commonly associated with recent supplementation or high dietary intake.
Because circulating Vitamin C can change relatively quickly, the result should be interpreted alongside dietary pattern rather than as a permanent measure of nutritional status.
