Case: Patient Anlan Dicco, a 23-year-old female who is pregnant, came back to the laboratory for a repeat oral glucose tolerance test (OGTT).

The repeat test was necessary due to indeterminate results from the previous OGTT conducted 2 days ago. The physician also ordered a CBC, HBsAg, RPR, HIV screening, and urinalysis as part of the routine screening tests for pregnant women during their first prenatal visit.
