ABSTRACT:
Use of13C glucose in an analytical assay to monitor glucose metabolism by measurement of labeled exhaled CO2is provided. A breath test and kit for performing the breath test are described for the diagnosis of diabetic indications and monitoring of glycemic control. The breath test utilizes the measurement of expired13C-labeled CO2following the ingestion of a13C-enriched glucose source.
