- Additional information
α and β-carotenes are plant pigments. This method measures the quantity of fortified and natural-occurring α and β-carotenes in food products and supplements. For products containing multiple forms of Vitamin A, carotenes and retinol can be added together to meet requirements for the NLEA nutrition label. Please let us know if results need to be reported as Dietary Carotenes (mcg RAE/100g) or Supplemental Carotenes (Supp. mcg RAE/100g) for your sample.

We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
We will report the Carotene results in mcg RAE (retinol activity equivalents) per 100g of sample. Upon request, we can also report in IU (international units). The mcg RAE unit is now the standard Vitamin A unit for nutrition labeling in the United States.
