a complete history and physical examination, the doctors will perform
a battery of laboratory tests. There are numerous tests available
to diagnose diabetes, such as a urine test, blood test, glucose-tolerance
test, fasting blood sugar and the glycohemoglobin (HbA1c) test.
A urine sample will be tested for glucose and ketones (acids
that collect in the blood and urine when the body uses fat instead
of glucose for energy).
A blood test is used to measure the amount of glucose in
A glucose-tolerance test checks the body's ability to process
glucose. During this test, sugar levels in the blood and urine are
monitored for three hours after drinking a large dose of sugar solution.
The fasting blood sugar test involves fasting overnight and
blood being drawn the next morning.
The glycohemoglobin test reflects an average of all blood
sugar levels for the preceding two months.
