An observational study in Glycogen Storage Disease Type Ia, sponsored by Connecticut Children's Medical Center. Recruiting at 1 site in United States. Open to participants aged 0 Years to 60 Years. Per ClinicalTrials.gov, last updated 2026-03-06.
Sponsored by Connecticut Children's Medical Center · Observational
The goal of this observational study is to determine if home lactate meters (both capillary and serum sample) are accurate, compared to lab serum lactate in a population of patients with glycogen storage disease type 1a and to determine if the Accu Chek Guide glucometer (capillary sample) is accurate, in a population of patients with glycogen storage disease type 1a.
The goal of this observational study is to determine if home lactate meters (both capillary and serum sample) are accurate, within 20% of lab serum lactate reading 95% of the time, in a population of patients with glycogen storage disease type 1a and to determine if the Accu Chek Guide glucometer (capillary sample) is accurate, within 20% of lab serum glucose reading 95% of the time, in a population of patients with glycogen storage disease type 1a.
