How's the glucose test at kkh?

towards end of 2nd trimester. they will take blood before u drink. then they will give u orange flavour sugar drink (super sweet ) then wait 1h .take blood again. then wait 1h then take again. total take 3 blood test . u cannot vomit out.. if not u have to come back next time to test again. before the test u have to fast for 12h. no eat no drink. plain water is fine. Good luck !
