I think depende sa OB mo po. In my case, I have a normal sugar level, and I have no gest diabetes in my 1st pregnancy, but still, my OB requires me to undergo OGTT in my 2nd pregnancy.
hindi naman po required pero kung may history ka of diabetes or gestational diabetes sa prev preg, mas maganda magpatest kasi dun malalaman if mataas blood glucose mo.
Ako sis di po nirequired. Pero twice ako nag fasting blood sugar test puros normal naman po kaya di na ako pinag Ogtt ng Ob ko.
