Descrizione dettagliata
Subjects are recruited at two different sites.
Site 1: In group 1 subjects will on their regular stay in the clinic perform four measurement sessions a day. A measurement session consist of a reference capillary blood sample and two measures on the IMD.
Site 2: The study in group 2 consists of 26 home-based measurements and two in-clinic days. During the home measurements, 6 measurement sessions will be performed by the subjects a day. A measurement session consists of two reference BGMs, two reference CGMs and two measurements on the device. On in-clinic visits, subjects will be administered high glucose breakfast and the following 6-7 hours, measurement sessions are performed every 15 minutes.

- Be willing to provide written signed and dated informed consent
Exclusion Criteria:
- Inability to comply with the study procedures as described by the study protocol, according to the opinion of the investigator, due to e.g. known psychiatric diagnoses, lack of cognitive ability, alcohol dependency, drug use, psychosocial overload

Sperimentale: RSP-09-02
Enrolled subjects will measure at home for 26 six days and visit the clinic two times.
During home measurements, 6 measurement sessions will be performed by the subject a day.
A measurement session consists of two BGMs, two CGMs and two measurements on the Prototype 0.3.
On in-clinic visits the subject will be administered a high glucose breakfast and the following 6-7 hours, measurement sessions will be performed every 15 minutes.
