Editing Glucose tolerance test (section)

===Procedure===
# A zero time (baseline) blood sample is drawn.
# The patient is then given a measured dose (below) of glucose solution to drink within a 5-minute time frame.
# Blood is drawn at intervals for measurement of glucose ([[blood sugar]]), and sometimes [[insulin]] levels. The intervals and number of samples vary according to the purpose of the test. For simple diabetes screening, the most important sample is the 2 hour sample and the 0 and 2 hour samples may be the only ones collected. A laboratory may continue to collect blood for up to 6 hours depending on the protocol requested by the physician.
