Study information
Scientific title
A non-randomised interventional clinical laboratory study to assess whether Lein's novel non-invasive glucose measurement technique offers a viable alternative to the current invasive capillary blood glucose solution
Acronym
DRN208
Study hypothesis
To assess whether Lein's novel non-invasive glucose measurement technique offers a viable alternative to the current invasive capillary blood glucose solution.
The purpose of this trial was to check for correlation between measured results taken from Lein's meter, the current leading capillary glucose meters and a gold standard venous blood laboratory measurement.

Condition
Topic: Diabetes Research Network; Subtopic: Both; Disease: Device studies
Intervention
Volunteers were tested over a period of 4 hours with blood glucose readings taken with conventional finger stick meters and a gold standard venous blood meter every 15 minutes. Eye data was also collected every 15 minutes in order to enable the investigating team to compare the readings. The volunteers were provided with a sandwich lunch part way through the trial in order to produce a change in their blood glucose levels.
