Carotene (Beta Carotene) Test in Colorado

A carotene (beta carotene) test measures the amount of beta carotene in your blood. Beta carotene is a nutrient the body converts into vitamin A, which supports vision, skin, and immune function. Clinicians may order it to check for a deficiency or to monitor a condition that affects how the body absorbs fats and fat-soluble vitamins.

What it measures

Beta carotene — The main form of carotene measured; a marker of vitamin A status and fat absorption.
Total carotenoids — A broader measure that may include related plant pigments such as lutein and lycopene.
Vitamin A (retinol) — Sometimes measured alongside beta carotene to assess overall vitamin A status.
Lipids (cholesterol, triglycerides) — Carotene travels with fats in the blood, so lipid levels can help interpret results.

Who it is for

The test is usually ordered by a primary care clinician, gastroenterologist, or dietitian when someone has symptoms of vitamin A deficiency, a condition that causes poor fat absorption, or a diet very low in fruits and vegetables.

Preparation

Fasting is often not required, but your clinician may ask you to fast if cholesterol or triglycerides are being measured at the same time. Tell your clinician about any vitamin or carotene supplements you take, since they can affect the result.

Results and what they mean

Results are reported as a number with a reference range, and your clinician interprets them alongside your diet, symptoms, and other tests. Low or high values do not by themselves diagnose a condition. This is general information only and is not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

Do I need to fast for this test?

Not always. If only beta carotene is being measured, fasting is usually not needed. If lipids are measured at the same time, you may be asked to fast for several hours.

Will eating carrots change my result?

Yes. A recent meal rich in carotene or a carotene supplement can raise the level. Tell your clinician what you ate or took before the test.

What can cause a low beta carotene level?

A diet low in fruits and vegetables, poor fat absorption, or certain health conditions can lower it. Your clinician will consider these along with your symptoms.

How long until I get results?

Results are typically available within 1 to 3 business days, though this can vary by laboratory.
