Glucose Tolerance Test
Start with the big picture
OGTT results depend on preparation, glucose administration, timing of blood sampling, and accurate specimen handling. The lesson outlines when testing may be considered or unsuitable, how to prepare, and the standard oral glucose load and sampling approach. It introduces interpretation of two-hour plasma glucose results, including impaired glucose tolerance and diabetes thresholds, alongside gestational diabetes criteria. The source also covers intravenous testing in selected circumstances, glucose-curve patterns, and factors that can affect results. These details help connect the test’s measurements with clinical interpretation while emphasizing conditions that may distort findings.

- Distinguish normal, impaired, and diabetic two-hour glucose results.
- Identify gestational diabetes criteria and selected uses of intravenous testing.
- Recognize factors and specimen-handling issues that can affect results.
