Final answer:
Tests for initial screening of type 2 diabetes are Fasting Blood Glucose, Blood Glucose Tolerance Test, and Glycosylated Hemoglobin A1c; therefore, all the given options are used for screening.
Step-by-step explanation:
The tests used for the initial screening of a patient for type 2 diabetes include: Fasting Blood Glucose, Blood Glucose Tolerance Test, and Glycosylated Hemoglobin A1c. A fasting blood glucose level provides information about blood sugar levels after fasting, which can indicate diabetes if the levels are abnormally high.
The glucose tolerance test assesses how the body processes glucose and is particularly useful when fasting blood glucose levels are high but not definitive, or when a patient has a high renal threshold and shows normal fasting glucose levels. Glycosylated hemoglobin A1c measures average blood sugar levels over months, reflecting long-term glucose control and aiding the management of diabetes. Therefore, the correct answer is D, which includes all of the aforementioned tests as part of the initial screening process for type 2 diabetes.
