Overview of the Carotenes (Beta Carotene)
The Carotenes (Beta Carotene) blood test is a specialist nutritional investigation that measures the concentration of beta carotene circulating in the blood.
Beta carotene is a naturally occurring carotenoid found mainly in yellow, orange and green fruit and vegetables, including carrots, sweet potatoes, pumpkin, spinach, mangoes and other carotenoid-rich foods.
It is a provitamin A carotenoid, meaning the body can convert beta carotene into vitamin A according to physiological requirements. Beta carotene also has antioxidant properties and forms part of the body's wider nutritional and antioxidant system.
The test contains 1 biomarker: Carotenes (Beta Carotene). It may be requested when nutritional status, excessive carotene intake or impaired intestinal absorption of fat-soluble nutrients is being investigated.
Because beta carotene is absorbed alongside dietary fat, reduced concentrations can occur in some people with malnutrition, steatorrhoea or disorders affecting fat absorption. Higher concentrations are commonly associated with increased consumption of carotene-rich foods or beta carotene supplements.
Markedly elevated beta carotene can cause carotenoderma, producing yellow-orange discolouration of the skin, particularly on the palms and soles. Unlike jaundice, the whites of the eyes generally remain unaffected.
Beta carotene should not be interpreted as a direct substitute for Vitamin A (Retinol). Although the body can convert beta carotene into vitamin A, the two measurements provide different information and should be interpreted within the wider nutritional and clinical context.
What Does the Carotenes (Beta Carotene) Test Check?
This test measures 1 biomarker.
Carotenes (Beta Carotene)
Measures the concentration of beta carotene circulating in the blood. Beta carotene is a plant-derived carotenoid and precursor of vitamin A. The result may provide supporting information about carotene intake, nutritional status, excessive carotene consumption and selected conditions affecting intestinal fat absorption.
Who May Benefit From the Carotenes (Beta Carotene) Test?
This test may be suitable for people requiring targeted assessment of beta carotene because of nutritional concerns, gastrointestinal symptoms, possible malabsorption or unexplained yellow-orange skin pigmentation.
Suspected nutritional deficiency - Low beta carotene concentrations may occur when dietary carotene intake or overall nutritional intake is inadequate.
Possible intestinal malabsorption - Because carotenoids are absorbed alongside dietary fat, reduced beta carotene may provide supporting information when fat malabsorption is suspected.
Persistent steatorrhoea - Pale, greasy or difficult-to-flush stools may occur when fat absorption is impaired and can justify broader nutritional investigation.
Chronic gastrointestinal symptoms - Persistent diarrhoea, unexplained weight loss or other digestive symptoms may lead to investigation of nutrient absorption.
Unexplained yellow-orange skin pigmentation - Elevated beta carotene can contribute to carotenoderma and may be considered when skin colour changes occur without yellowing of the eyes.
High intake of carotene-rich foods - People consuming unusually large quantities of carotenoid-rich foods may develop increased circulating beta carotene.
Beta carotene supplement use - Testing may provide useful information where high-dose or prolonged beta carotene supplementation is being reviewed.
Previous abnormal carotene results - Repeat testing can help establish whether a previously low or high beta carotene concentration persists.
Specialist-requested nutritional testing - The test can be arranged privately where a gastroenterologist, dietitian, nutrition specialist or GP has specifically requested beta carotene measurement.
How to Prepare
Do not stop prescribed supplements or medication solely to alter your beta carotene result unless instructed by the healthcare professional responsible for your care.
Providing an accurate dietary and supplement history can be particularly useful because circulating beta carotene is strongly influenced by intake as well as intestinal absorption.
Symptoms and Reasons to Consider the Carotenes (Beta Carotene) Test
You may wish to consider the Carotenes (Beta Carotene) test if nutritional status, possible malabsorption or excessive beta carotene exposure is being investigated.
Yellow-orange skin discolouration - Excess beta carotene can accumulate within the skin and produce carotenoderma, particularly affecting the palms and soles.
Yellow skin with normal-looking whites of the eyes - Carotenoderma usually does not affect the sclera, which can help distinguish it from jaundice.
Persistent diarrhoea - Chronic diarrhoea may occur with gastrointestinal disorders that interfere with normal nutrient absorption.
Pale, greasy or difficult-to-flush stools - Steatorrhoea can indicate impaired digestion or absorption of dietary fat.
Unexplained weight loss - Weight loss occurring alongside gastrointestinal symptoms can warrant investigation for malabsorption and nutritional deficiency.
Restricted dietary intake - Diets containing very limited fruit, vegetables or other carotenoid sources may contribute to low beta carotene concentrations.
Multiple nutritional deficiencies - Unexpected deficiencies affecting several vitamins or micronutrients may raise suspicion of impaired nutrient absorption.
Very high consumption of carotene-rich foods - Regularly consuming large quantities of carrots, sweet potatoes, pumpkin or similar foods can increase circulating beta carotene.
Use of high-dose beta carotene supplements - Supplementation can significantly influence the measured concentration and may contribute to carotenoderma.
Beta carotene abnormalities can occur for several reasons, and neither a low nor high result establishes an underlying diagnosis by itself.
Low concentrations should be interpreted alongside dietary intake, gastrointestinal symptoms and other nutritional markers. High concentrations are frequently related to diet or supplementation but should still be considered in the context of the wider clinical picture.
Yellowing of the skin together with yellowing of the whites of the eyes, dark urine, pale stools, abdominal pain or other symptoms suggestive of jaundice requires appropriate medical assessment rather than assuming the colour change is caused by beta carotene.
How to Book Your Carotenes (Beta Carotene) Test

A trained professional will collect your blood sample safely and efficiently at the clinic or during your arranged home or hotel visit.
Laboratory analysis
Your sample is sent to the laboratory, where beta carotene is measured using specialist nutritional laboratory analysis.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, gastroenterologist, dietitian, nutrition specialist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Carotenes (Beta Carotene) test is approximately 2 business days after your sample arrives at the laboratory.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround therefore begins when the laboratory receives the sample rather than necessarily from the time your blood is collected.
Specialist nutritional testing may occasionally require repeat analysis or additional laboratory review, which can extend the expected turnaround.
Understanding Your Results
Your Carotenes (Beta Carotene) result shows the concentration of beta carotene detected in your blood according to the reference interval used by the analysing laboratory.
A low result may reflect limited dietary intake of carotenoid-rich foods. Reduced concentrations can also occur with poor overall nutritional status or conditions affecting intestinal absorption of dietary fat.
Because beta carotene is fat-soluble, persistently reduced levels may provide supporting information when malabsorption is already suspected because of symptoms, medical history or other abnormal nutritional markers.
A low beta carotene result does not identify the cause of malabsorption and should not be used independently to diagnose a gastrointestinal condition.
Higher beta carotene concentrations are commonly associated with high dietary intake or beta carotene supplementation.
Marked elevations can produce carotenoderma, resulting in yellow-orange skin pigmentation. This is generally most noticeable on the palms and soles and typically does not cause yellowing of the whites of the eyes.
Beta carotene results should also not be interpreted as equivalent to Vitamin A (Retinol). Although beta carotene is a precursor from which vitamin A can be produced, direct retinol measurement answers a different nutritional question.
Reference intervals can vary between laboratories. Results should therefore be interpreted according to the laboratory report and alongside dietary intake, supplement use, lipid status, gastrointestinal symptoms and other nutritional investigations.
