the arrangement of hospital is totally different, i took the test at PYN on last sat and return to the hospital yesterday to attend the class and see the nutritian to follow the diet. my GDM index was 7.9 which is just 0.1 exceed their passing rate (7.8 or below), and the index should be between 4-7 for 2 hours after meal.
I was requested to buy the small blood testing machine and do the test everyday and have doctor visit every 2 weeks to monitor the progress.
I think they will definitely get in touch with you if your result is fail.
