Non-invasive Glucose Measurement With Raman Technology in Patients With Type 1 and Type 2 Diabetes
Non-invasive Glucose Measurement With Raman Technology. Calibration of Newly Developed Devices in Patients With Type 1 and Type 2 Diabetes - Glucobrunn Study
연구 개요
상세 설명
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 able to follow the instructions provided to him/her by the study site and perform all study tasks as specified by the protocol
- 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

- Systemic or topical administration of glucocorticoids for the past 7 days
- Undergoing dialysis treatment
- Have extensive skin changes/diseases at the proposed measurement site (thenar) that could interfere with the accuracy of interstitial glucose measurements
- Have a concomitant medical condition which could interfere with the study devices (study arm 1: intake of acetaminophen study arm 2: intake of salicylic acid or higher doses of ascorbic acid)
- Unsuitable for participation due to any other cause as determined by the Investigator. Mental incapacity, unwillingness or language barriers precluding adequate understanding or co-operation e.g. with required documentation
