Hi, During pregnancy a blood glucose level below 140 is considered as normal, where as a level between 145-199 is diagnosed as pre-diabetic and a level of 200 is diagnosed as diabetic. As you are having your blood sugar 182, hence it is to be taken as pre-diabetic. These patients may eventually have a risk of developing diabetes, hence further screened by 3 hour screening test. In 3 hour test,1st sample is taken after a complete fasting of 8 hours. Then you are given 100 gm. of sugar. After this, 2nd sample is taken after1 hour, 3rd after 2 hours &4th sample after 3 hours. The four samples are then analysed for glucose levels. Normal limits of these samples is taken as below--- * Fasting up to 95 mg% * After 1 hour up to 180 mg% * After 2 hours up to 155 mg% * After 3 hours up to 140 mg * If one sample out of 4 is above normal, then patient will be tested again after 4 weeks. * If out of 4 any 2 or more samples are above normal, then the patient will be taken as of gestational diabetes and will be further managed with all the precautions like a patient of diabetes. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Satnarain Bansal, General & Family Physician
