Assess gestational diabetes risk factors and check glucose values against thresholds.
Diagnostic thresholds for gestational diabetes differ between guidelines, so the same values can be diagnostic under one and not another. Risk factors determine screening timing rather than diagnosis. Gestational diabetes is frequently asymptomatic, which is why screening is offered on the basis of risk factors rather than symptoms.
Gestational Diabetes
Risk factors are scored, and glucose values compared against commonly cited diagnostic thresholds
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. Thresholds vary between national guidelines and this cannot diagnose gestational diabetes. Pregnancy care and glucose testing must be managed by your maternity team. Contact them promptly with any concern about your pregnancy.
