Carotenoid measurements
"Carotenoid measurements of the eye (macula) are obtained through non-invasive ophthalmic photographs using the Heidelberg Spectralis imaging system.~Carotenoid measurements of the skin are measured by a laboratory instrument that uses a painless blue laser light for exposure of the skin and a photodetector for scattered light.~Carotenoid measurements in the blood are obtained through routine venipuncture."
