Ay, that's a tricky one! If kaunti lang ang suka after the first blood draw, honestly most docs don't require a repeat, kasi the extraction itself ay quick lang and minimal amount of blood talaga, so usually hindi ito affected. But para sure, best to ask your OB directly kasi sila ang may final say on whether the sample is still valid or if they need to retake it, lalo na depende kung gaano kalaki ang suka at anong oras na siya nangyari during the test. Better safe than sorry with OGTT results, especially since crucial ang accurate reading para sa gestational diabetes screening.
