Is it necessary to test gestational diabetes through gtt or i can have RBS test to screen it?
GDM is usually asymptomatic but has serious consequences that can be reduced by treatment9, making it a candidate for screening. Contenders for screening tests are glucose challenge (mini-GTT) and fasting glucose test (venous or capillary10 blood specimens). However, currently in the UK, NICE does not recommend routine antenatal screening due to lack of evidence but do maintain that healthcare providers “remain alert to signs or symptoms of conditions which affect the health of the mother and fetus, such as.. diabetes”. 11 Thus clinicians must decide on whom they should focus their efforts and usually a risk factor based scheme is used to determine pregnancies that should receive further testing for GDM. This method will only detect about 50% of women with gestational diabetes.12 Urinalysis Urine should be checked for glucose at every antenatal visit. Renal blood flow and glomerular filtration rate (GFR) rise in pregnancy with the result that the renal threshold for glycosuria is reduc
