An observational study in Glycogen Storage Disease Type IA, Glycogen Storage Disease Type I and Glycogen Storage Disease Type IB, sponsored by Connecticut Children's Medical Center. Recruiting at 1 site in United States. Open to participants aged Up to 60 Years. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Connecticut Children's Medical Center · Observational
The goal of this study is to determine if the Lactate Plus meter is accurate compared to lab lactate levels, and to determine if the Accu chek guide glucometer is accurate compared to lab serum glucose levels in patients with Glycogen Storage Disease Types Ia, Ib and XI.
To determine this, patient's will have a one-time planned admission to Connecticut Children's for approximately 8 hours and receive hourly blood draws as well as finger-sticks.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
