ORCHID = Optimisation of Rural Clinical and Haematological Indicators for Diabetes in pregnancy; GDM = gestational diabetes mellitus; PG = plasma glucose; FLOXICE protocol = fluoride-oxalate (FLOX) samples stored immediately on ice; FLOXRT protocol = FLOX samples stored at room temperature (RT); FC Mix protocol = fluoride-citrate-EDTA samples stored at RT; PST protocol = lithium-heparin plasma separation tubes centrifuged within 5 min of collection at 1300× g for 5 min and stored at RT. † GDM diagnosed if one or more International Association for Diabetes in Pregnancy Study Groups (IADPSG) 2010 glucose criteria were met: FPG ≥ 5.1 mmol/L; 1-h PG ≥ 10.0 mmol/L; 2-h PG ≥ 8.5 mmol/L.
