- A male patient has had successive fasting plasma glucose readings of 115, 110, and 122 mg/dl. The healthcare provider will inform him that
- To obtain an accurate spectrophotometric measurement of the glucose concentration in the sample
- In the spectrophotometric assay used in this experiment, the as the glucose concentration in the sample increases.
- A female patient has had successive fasting plasma glucose readings of 130, 140, and 128 mg/dl. The healthcare provider will inform her that

- A laboratory technician withdraws a blood sample from a vein in your upper arm knowing that
Review Sheet Results
- What is a glucose standard curve, and why did you need to obtain one for this experiment? Did you correctly predict how you would measure the amount of plasma glucose in a patient sample using the glucose standard curve?
- Which patient(s) had glucose reading(s) in the diabetic range? Can you say with certainty whether each of these patients has type 1 or type 2 diabetes? Why or why not?
- Describe the diagnosis for patient 3, who was also pregnant at the time of this assay.
- Which patient(s) had normal glucose reading(s)?
- What are some lifestyle choices these patients with normal plasma glucose readings might recommend to the borderline impaired patients?
