Study summary

This clinical study has been launched to collect spectral raman data paired with validated glucose reference values in private homes of subjects.

Read the detailed description

Subjects will collect 2-4 daily optical raman readings paired with capillary Blood Glucose comparator in own home with maintaining usual routines. Subjects will either collect data for 30 days during a 60 days period or collect data for 90 days during 6 months.

Study arms

  • Experimental
    Short term collection of IMD data

    Subjects will collect spectral raman data on WM3.4NR four times a day for 30 days distributed over a time period of 60 days. Each timepoints are conducted in duplicate. Spectral data will be compared to standard BG measurements.

    Device: WM3.4NR

  • Experimental
    Long term collection of IMD data

    Subjects will collect spectral raman data on WM3.4NR four times a day for the initial 30 days, distributed over a time period of 60 days. Subjects will for the remaining 60 days of measurements, distributed over 120 days collect spectral data twice a day. Each timepoints are conducted in duplicate. Spectral data will be compared to standard BG measurements.

    Device: WM3.4NR

Interventions

  • DeviceWM3.4NR

    Investigational Medical Device collecting spectral raman data from tissue.
