Brief Summary

This is a single-center, open-label, prospective study. Blood glucose is measured at different time points during oral glucose tolerance test and hypoglucose clamp test in healthy subjects, using both venous plasma and multi-channel microspatial offset Raman scattering spectroscopy (mμSORS). Venous plasma glucose was set as gold standard. The two measurements were collected synchronously so as to calculate the mean absolute relative difference (MARD) and the consensus error grid (CEG). Accuracy of non-invasive blood glucose testing by mμSORS will be in-depth validated specifically in the 3-10 mmol/l glucose range.

Conditions

Diabetes Mellitus

Outcome Measures

Primary Outcomes (2)

• Mean absolute relative deviation (MARD) of venous plasma glucose and glucose values measured by mμSORS at each time point of OGTT and hypoglucose clamp tests.

  Glucose will be measured using both intravenous sampling (plasma) and multi-channel microspatial offset Raman scattering spectroscopy (mμSORS) detection synchronously.

  2 months

• Consensus Error Grid (CEG) for venous plasma glucose and glucose values measured by mμSORS at each time point of OGTT and hypoglucose clamp tests.

  Glucose will be measured using both intravenous sampling (plasma) and multi-channel microspatial offset Raman scattering spectroscopy (mμSORS) detection synchronously.

  2 months

Secondary Outcomes (2)

• MARD for two measurement methods in different blood glucose ranges.

  2 months

• Incidence of Treatment-Emergent Adverse Events.

Clinical Validation of mμSORS for Noninvasive Blood Glucose Detection in healthy subjects

EXPERIMENTAL

Enrolled subjects will perform oral glucose tolerance test or hyperinsulin-hypoglucose clamp test. A measurement session of blood glucose consists of plasma sample and a measurement by mμSORS will be conducted synchronously.

Device: Multi-channel Microspatial Offset Raman Scattering Spectroscopy (mμSORS) for Noninvasive Blood Glucose Detection

Interventions

Multi-channel Microspatial Offset Raman Scattering Spectroscopy (mμSORS) for Noninvasive Blood Glucose Detection DEVICE

Blood glucose of participants were measured by venous plasma and multi-channel microspatial offset Raman scattering spectroscopy (mμSORS). The two measurements were collected synchronously and analyzed.

• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male or female.
• Aged\>=18 years for OGTT participants or aged between 20 and 40 years for hypoglucose clamp tests participants.
• Fasting blood glucose (FPG) \< 6.1 mmol/L and glycated hemoglobin (HbA1c) \< 5.7% during the screening period.
• There are no scars, obvious pigmentation and other factors that interfere with the detection of the palm skin to be tested.
• Confirmed as healthy based on the results of physical examination, medical history, vital signs and clinical laboratory tests.
• Fully understand the nature, significance, possible benefits, possible inconveniences or potential risks of this research, and should also understand the research procedures, be willing to complete the entire research process, and provide written consent form.

You may not qualify if:

• With diabetes history.
• Any history of serious clinical diseases such as circulatory system, endocrine system, nervous system, digestive system, respiratory system, hematology, immunology, psychiatry or metabolic abnormality, or any other disease that can interfere with the test results, which the investigator considers significant.
• Alcohol dependency or drug abuse.
• Those who have participated in clinical trials of other drugs within 3 months before screening (since the last visit of the previous trial).
• Those who have used any drugs that affect blood glucose levels (such as insulin, oral hypoglycemic drugs, steroid hormones, thyroxine, etc.) within 28 days before screening;
• Pregnancy or lactation period.
• Difficulty in venous blood collection or fainting of needles or blood.
• Other circumstances that the investigator considers inappropriate to participate in the study.
