Diagnosis is a confirmation of GDM in people with a positive screening test. There are several tests for the diagnosis of GDM, but the most commonly test is OGTT. And what is OGTT? Usually OGTT is performed in women at an increased risk. For example, in women with previous GDM, the OGTT is performed early after diagnosis of gestation (Bartha, 2003) or when GDM is identified on a screening test.

For the diagnostic test, many hospitals in Australia use a 75g OGTT. Fewer hospitals use a 50g OGTT and 100g OGTT (Rumbold and Crowther, 2001). The requirement of elevated blood glucose levels also differs between Australia hospitals (the requirement ranges between 1-3 elevated blood samples). There is also variety in the management for GDM. Regimens include self-monitoring of blood glucose level, laboratory monitoring of blood glucose level, exercise, diet control, and a combination of diet and insulin therapy (Rumbold and Crowther, 2001).

Glucose load and timing also vary in different places around the world (Scott, 2002). In some countries, where large glucose loads are used, women may feel uncomfortable using 75 g glucose-loads (Scott, 2002). Moreover, the test results are less satisfactory with this higher load than with lower loads (Scott, 2002). There are also side effects with the high concentrated glucose load, for example nausea, vomiting and bloating may affect the test results (Murphy, 1994; Shushan and Samueloff, 1998). Different timing of assessment also influences the results of the test.
