A 1-step approach for gestational diabetes (GDM) screening using a 75 g-oral glucose tolerance test (75 g-OGTT) has been recommended. We undertook an audit (January 2007-June 2010) to assess adherence to an existing 2-step approach (50 g-glucose challenge test followed by a 75 g-OGTT). Adherence was sub-optimal. Overall follow-up was missed in 14.5% of those screened. Only 36% of those who met dysglycemia criteria for a follow-up 75 g-OGTT received the test as per step 2 of the protocol.
