The diagnosis of GDM is made following the GTT where a
fasting plasma level is greater than or equal to 5.5mmol/l, and a two hour GTT plasma level post a
75g oral glucose load is greater than or equal to 8.0mmol/l. However, more recently research
published by ADIPS suggests a slightly different criterion: with a diagnosis of GDM made
following a fasting glucose of greater than or equal to 5.1mmol/l and a two hour GTT post glucose
load of greater than or equal to 8.5mmol/l (Nankervis et al. 2012).
