The Glucose Challenge Test (GCT) is a screening test for gestational diabetes, conducted over three hours. **First hour:** The patient drinks a glucose solution, and blood is drawn after one hour to measure glucose levels. **Second hour:** Another blood sample is taken to measure how the body is processing the glucose. **Third hour:** A final blood sample is drawn to track glucose levels over the three-hour period. The test helps identify how well the body manages glucose over time, and abnormal results may indicate gestational diabetes, requiring further monitoring and treatment.

The Glucose Challenge Test (GCT) is a crucial screening tool for diagnosing gestational diabetes, administered over a three-hour period. Each hour involves specific steps to monitor how the body processes glucose.

**First Hour: Initial Glucose Intake**

The test begins early in the morning, with the patient arriving at the clinic after fasting overnight. The atmosphere in the waiting room is one of quiet anticipation. Sarah, who is eight months pregnant, sits nervously, thinking about the sugary drink she’s about to consume. The nurse calls her name, and she’s handed a glucose solution, which she drinks quickly, its sweetness almost overwhelming. Sarah then returns to the waiting area, feeling the sugary rush coursing through her veins. An hour later, a phlebotomist draws her blood to measure her initial glucose level. This first draw is critical for establishing how her body initially responds to the glucose intake.

**Second Hour: Monitoring Glucose Processing**

As the second hour begins, Sarah tries to distract herself by reading a magazine. The clinic staff advise her to remain seated and avoid physical activity to ensure accurate results. The waiting room is filled with other expectant mothers, some chatting quietly, others lost in thought. When the clock strikes the second hour, Sarah is called back for another blood draw. This sample will show how her body is processing the glucose, indicating whether her insulin levels are sufficient to manage the sugar load. She hopes for normal results, knowing that any abnormalities could complicate her pregnancy.

**Third Hour: Final Glucose Assessment**

The third and final hour feels the longest. Sarah feels a mix of anxiety and anticipation as she waits for the last blood draw. The initial rush of the glucose drink has worn off, leaving her feeling a bit tired. Finally, she’s called back for the third blood sample. This final test will reveal how her body has managed the glucose over the entire period.

Once the blood is drawn, Sarah is free to go home, though she’ll have to wait a few days for the results. The data collected during these three hours will help her healthcare provider determine whether she has gestational diabetes and if any interventions are necessary to ensure a healthy pregnancy for both her and her baby.
