Frequently asked questions
Is Fasting Plasma Glucose high or low in Type 1 Diabetes?
Elevated. Studies summarised in the OSMF atlas report higher Fasting Plasma Glucose in Type 1 Diabetes than in the reference group of the cited comparison (T1D patients vs healthy/normal reference range). Source: Yang et al. 2024.
Which test measures Fasting Plasma Glucose?
The atlas record does not list a standardised clinical test code (LOINC) for Fasting Plasma Glucose, which usually means it was measured with research assays or study-specific protocols rather than a routine clinical panel. Check the cited source for the exact method.
Is one abnormal Fasting Plasma Glucose result diagnostic of Type 1 Diabetes?
No. No single biomarker is diagnostic of Type 1 Diabetes. Fasting Plasma Glucose findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
Is Fasting Plasma Glucose specific to Type 1 Diabetes?
No. The same marker is also reported in Type 2 Diabetes in this atlas, so it reflects shared biology (for example inflammation or vascular stress) rather than a condition-specific signature.
