About this trial
More than 100 million U.S. adults are now living with diabetes or prediabetes. Investigators still do not fully understand how diabetes develops and how the disease worsens. Insulin is a hormone that helps the body use sugar as a fuel and control blood-sugar levels. People with diabetes have problems making insulin. This is because their insulin-producing beta cells -in the pancreas-are damaged or destroyed. A biomarker is a biological molecule (such as DNA, RNA (the genetic material of cells) or protein) that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker can be measured and found in blood and/or other body fluids (such as saliva and urine). Understanding the biology of beta cells could help find diabetes-related biomarkers. The discoveries from this research could help with early diagnosis of diabetes and lead to the creation of therapies for treating diabetes.
Eligibility criteria
Qualifiers
Documented informed consent/ assent from the subject
Type 1 diabetes patients (including pediatric patients) -OR-
Adult type 2 diabetes patients -OR-
Volunteers who are islet auto-antibody positive (i.e. insulin, GAA, IA-2, IAA and ZnT8 antibodies) with HbA1c ≤ 5.6% (including pediatric patients)-OR-
Disqualifiers
Control subjects must not have any chronic conditions or have undergone cellular, tissue or organ transplant
Sickle cell disease or anemia (exception: anemia that is corrected with treatment and source documents confirm corrected blood parameters current within 6 months of blood draw)
Active infection
Active malignancy (i.e., currently undergoing treatment)
Trial design
Treatments tested in this trial
- One-time blood (up to 100 ml) will be drawn and the amount of blood drawn is based on weight. Saliva and urine will be collected during the blood draw visit.
