Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Reflectance Spectroscopy Primary · Baseline and Month 12

Reflectance Spectroscopy (RS) is measured by Reflection Units. Possible scores range from 0 (no carotenoids detected) to greater than 500. Change = (Month 12 Score - Baseline Score).

Late Genetic Results Disclosure290.9± 12.5
Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Resonance Raman Spectroscopy Primary · Baseline and Month 12

Resonance Raman Spectroscopy (RSS) is measured in Resonance Raman Units (RRU). Possible scores range from 0 (no carotenoids detected) to greater than 100,000. Change = (Month 12 Score - Baseline Score).

Change in Ocular Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Macular Pigment Optical Volume Secondary · Baseline and Month 12

Macular Pigment Optical Volume (MPOV) is a unitless measure of the amount of carotenoids present in the macula. Possible scores range from 0 (no carotenoids detected) to greater than 50,000. Change = (Month 12 Score - Baseline Score).

Change in Serum Carotenoid Status in Response to Genetic Risk Disclosure Secondary · Baseline and Month 12

Serum carotenoid levels are measured in nanograms per milliliter (ng/mL). Possible scores range from 0 (no carotenoids detected) to greater than 1,000. Change = (Month 12 Score - Baseline Score).
