<unk>  is formally defined as "any degree of glucose intolerance with onset or first recognition during pregnancy". This definition acknowledges the possibility that a woman may have previously undiagnosed<unk>  mellitus, or may have developed<unk>  coincidentally with pregnancy. Whether symptoms subside after pregnancy is also irrelevant to the diagnosis. A woman is diagnosed with<unk>  when glucose intolerance continues beyond 24 to 28 weeks of gestation. The White classification, named after Priscilla White, who pioneered research on the effect of<unk>  types on perinatal outcome, is widely used to assess maternal and fetal risk. It distinguishes between<unk>  (type A) and pregestational<unk> <unk>  that existed prior to pregnancy). These two groups are further subdivided according to their associated risks and management. The two subtypes of<unk>  under this classification system are: * Type A1: abnormal oral glucose tolerance test (OGTT), but normal blood glucose levels during fasting and two hours after meals; diet modification is sufficient to control glucose levels * Type A2: abnormal OGTT compounded by abnormal glucose levels during fasting and/or after meals; additional therapy with insulin or other medications is required<unk>  which existed prior to pregnancy is also split up into several subtypes under this system: * Type B: onset at age 20 or older and duration of less than 10 years. * Type C: onset at age 10–19 or duration of 10–19 years. * Type D: onset before age 10 or duration greater than 20 years. * Type E: overt<unk>  mellitus with calcified pelvic vessels. * Type F: diabetic nephropathy. * Type R: proliferative retinopathy. * Type RF: retinopathy and nephropathy. * Type H: ischemic heart disease. * Type T: prior kidney transplant. An early age of onset or long-standing disease comes with greater risks, hence the first three subtypes. Two other sets of criteria are available for diagnosis of<unk> , both based on blood-sugar levels. Criteria for diagnosis of<unk> , using the 100 gram Glucose Tolerance Test, according to Carpenter and Coustan: * Fasting 95 mg/dl * 1 hour 180 mg/dl * 2 hours 155 mg/dl * 3 hours 140 mg/dl Criteria for diagnosis of<unk>  according to National<unk>  Data Group: * Fasting 105 mg/dl * 1 hour 190 mg/dl * 2 hours 165 mg/dl * 3 hours 145 mg/dl
