What this test is
The carotene (beta carotene) test is a blood test that quantifies the amount of beta carotene circulating in your bloodstream. Beta carotene is a provitamin A carotenoid found in colorful fruits and vegetables, and it plays a role in vision, immune function, and skin health. The test helps assess whether your intake or absorption of this nutrient is adequate.
What it measures
- Beta carotene — Reflects recent dietary intake and absorption of this provitamin A carotenoid.
- Vitamin A (retinol) — Sometimes measured alongside beta carotene to assess overall vitamin A status.
- Total carotenoids — May be reported to give a broader picture of carotenoid levels.
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if you have symptoms suggesting a vitamin A deficiency, such as night blindness or dry eyes, or if you have a condition that impairs fat absorption. It can also be used to monitor nutritional status in people with malabsorption disorders or those receiving certain treatments.
Preparation
Your lab will provide specific instructions, which may include fasting for several hours before the blood draw. Always follow the collection lab's directions exactly, as preparation can affect the results.
How results are reported
Results are typically reported as a concentration of beta carotene in your blood, along with a reference range. Reference ranges vary by laboratory, so your result should be interpreted using the range provided by the testing lab and in the context of your overall health.

FAQ
Frequently asked questions
Do I need to fast for a beta carotene test?
Some laboratories request fasting for several hours before the blood draw, while others do not. The instructions can vary, so it is important to check with the lab that will collect your sample. Following their specific preparation guidelines helps ensure accurate results.
What can affect my beta carotene level?
Recent intake of foods rich in beta carotene, such as carrots, sweet potatoes, and spinach, can raise your level temporarily. Certain medical conditions that affect fat absorption, as well as some medications, may also influence results. Your clinician can help interpret these factors.
Is a low beta carotene level dangerous?
A low level may indicate inadequate intake or absorption of beta carotene, which could affect vitamin A status over time. However, only a healthcare professional can determine whether your result is concerning and what it means for your health. Do not change your diet or supplements based on a test result without consulting your clinician.
How long does it take to get results?
Results are typically available within one to three business days after the sample reaches the laboratory. The exact turnaround time can vary depending on the lab's workload and other factors. Your ordering clinician will receive and discuss the results with you.
