1 Oral Glucose Tolerance Test (OGTT) Name Institution Course Professor Date

2 Oral Glucose Tolerance Test (OGTT) The OGTT's primary goal is to examine a person's capacity to manage blood glucose levels. It is used to detect gestational diabetes mellitus (GDM), a type of diabetes that occurs during pregnancy (Eyth et al., 2019). Fasting for at least 8 hours is required, followed by the intake of a glucose-containing solution and numerous blood glucose tests (typically fasting, 1 hour, 2 hours, and 3 hours) to reveal aberrant glucose metabolism during pregnancy. Target Group and Validation The OGTT is designed exclusively for pregnant women to diagnose gestational diabetes. It is not meant to be used in any other age group or situation. It has been evaluated and verified in pregnant women to detect gestational diabetes (Héctor Gallardo-Rincón et al., 2022). Clinical trials and research have shown its usefulness and reference values in this group. Predictive Ability The OGTT is considered a reliable and valid technique for detecting gestational diabetes. It is the gold standard for this purpose, with well-established reference ranges and diagnostic criteria. It delivers precise glucose readings at several time intervals, and high blood glucose levels at any two or more of these intervals (fasting, 1 hour, 2 hours, or 3 hours) are suggestive of gestational diabetes (Héctor Gallardo-Rincón et al., 2022). The predictive values are well- documented, and the test is reliable in detecting GDM. The OGTT is susceptible to aberrant glucose metabolism during pregnancy, particularly GDM. In research by Lapphart and Liabsuetrakul (2020), the pooled sensitivity and specificity were 79% and 74%, respectively, whereas sensitivity was more than 90% in others.

3 OGT is a critical test that I would incorporate into my advanced practice. This test would have been critical for my work with pregnant women, particularly those at risk of GDM, due to its reliability, validity, and predictive characteristics, which make it a standard test for diagnosing GDM.
