Summary

The goal of this clinical trial is to test microwave metamaterial glucose sensor on blood samples. It means to compare the results of glucose values obtained by microwave metamaterial sensor and by standard biochemical analyzer.

Detailed description

Participants will include physiological and pathological populations. Participants donate approximately 5 ml of blood sample. Three sample tubes will be collected from ten adult participants. In the first test tube, the blood glucose content will be determined by a validated biochemical analyzer (Roche, Switzerland). In the remaining volume of the blood sample, the dielectric parameters (relative permittivity and conductivity) will be estimated using a coaxial probe (Keysight, USA). Microwave metamaterial sensors with 5, 7 and 9 unit cells will be loaded with blood samples and the specific scattering matrices will be obtained using a vector network analyzer. The main monitored outcome measure will be the phase of parameter S21.

Conditions

• Diabetes

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	In vitro full blood diagnostic test.	Participant will donate approximately 5 ml blood sample. Later in a laboratory the sample will be processed in the microwave metamaterial sensor for non invasive blood glucose monitoring and standard biochemical analyzer. Specific dielectric properties and scattering parameters will be measured for blood glucose level determination.
