LOINC long common name : Deprecated PhenX measure - oral glucose tolerance test;
LOINC description : A bioassay to measure the concentration of plasma glucose 2 hours after drinking a
dextrose solution. The Oral Glucose Tolerance Test (OGTT), like the Fasting Plasma
Glucose test, can indicate whether a person has diabetes or is at high risk for developing
diabetes (pre-diabetes) and a number of other adverse health conditions (such as metabolic
syndrome) and premature mortality. However, the Oral Glucose Tolerance Test is a more
quantitative measure of glucose handling and impaired glucose tolerance than a fasting
glucose measurement.;
