  • Patent number: 11353446
    Abstract: Disclosed is a method for correlating a biomarker in a non-blood bodily fluid with the same biomarker in the blood of an individual, including: measuring, in a first period in time, the biomarker in non-blood bodily fluid and measuring the same biomarker in the blood of the same individual to establish an R ratio of [NBBF1]/[BB1], where [NBBF1] is the biomarker concentration in non-blood bodily fluid in the first period in time, and [BB1] is the biomarker concentration in the blood in the first period in time; storing the ratio in a memory; measuring, in a second period in time, the biomarker in non-blood bodily fluid to determine [NBBF2], where [NBBF2] is the biomarker concentration in the non-blood bodily fluid in the second period in time; and correlating the measured [NBBF2] with the R ratio to generate a correlated [BB2] biomarker concentration in the blood of the individual in the second period in time.

  • Publication number: 20220113292
    Abstract: Systems and methods for monitoring the health status of a subject are provided. In certain embodiments, the method includes: applying a sample provided from a subject to a signal enhancing detector configured to indicate an output that is representative of the sample; processing the output with a device configured to acquire the detector output as input data and process the input data to generate a report; and receiving the report. In certain embodiments, the device is a mobile device. In certain embodiments, the method further includes transmitting the sample-derived data in the device to a remote location where the transmitted data is analyzed; and receiving the results of the analysis. Also provided are systems for use in practicing the methods. Kits for use in monitoring the health status of a subject are also provided.
