Abstract: A system, apparatuses, and methods for assisting a person to improve their health. A person's initial blood sample spectra may be processed to identify components that have been found to reflect the impact of a lifestyle program, without identifying a biomarker in the blood. Each lifestyle program may be associated with its own set of spectra components or channel that indicate the impact of the program on blood spectra. Based on the person's initial blood spectra and the channel associated with each program, a process may generate a recommended set of programs that the person could use to improve their health. This set of programs may be filtered based on a demographic characteristic or characteristics of the person by comparing the set of programs to a ranked list of programs found helpful by people with a similar demographic characteristic.

Abstract: Systems, apparatuses and methods for the non-invasive measurement of a surrogate for a biomarker in a person's blood. In the example where the surrogate is a level of fat in the blood of the person and the biomarker is the level of triglycerides in the person's blood, the correlation between measurements of the surrogate and the level of triglycerides may be used to generate a recommendation to the person regarding a change in their intake of food, their exercise regimen, or another aspect of their lifestyle.

Abstract: A blood sample collector can be used to collect a blood sample from a subject. The blood sample collector can be placed in a receptacle of a spectrometer to measure spectral data from the blood sample while the blood sample separates. The container may comprise a window to allow light such as infrared light to pass through the container, with the blood sample at least partially separating within the container between spectral measurements, which can provide improved accuracy of the measurements and additional information regarding the sample. Measurements of the level of a biomarker surrogate in a person's blood may be used to assist the person to make beneficial changes to their diet, exercise regimen, or other aspects of their lifestyle.
