Glucose Measurement Using Microneedle Patches

The microneedle patch will collect interstitial fluid to be tested for glucose level. The microneedles are made from biocompatible polymers or metal. Participants will have fasting glucose levels measured four times, on an hourly basis, during the study visit.

The intravenous (IV) catheter will collect venous blood to be tested for glucose level. Participants will have fasting glucose levels measured four times, on an hourly basis, during the study visit.

The lancet will collect capillary blood to be tested for glucose level. Participants will have fasting glucose levels measured four times, on an hourly basis, during the study visit.
