Hello doctor I have done CBC, tsh, urine and gct CBC, tsh and urine done durning fasting, which is normal. Before doing gct I took breakfast then after half an hour took 50g glucon-D which we get in normal medical shop, then after one hour test was done which showed 285 Now I got doubt whether usual gluconD can be used for test or is there anything like we must take 75g glucose provided in hospital for maternity only..?? Can you please advice me on what to do now Should I take test again
