This series measures insulin before a glucose drink and again one and two hours later. The sequence shows how insulin production changes over the test.

Understanding the test
Also called Insulin Response Series
The three samples allow the clinician to distinguish a baseline measurement from the earlier and later hormone response. A single insulin value cannot show that sequence.
The series provides more detail than a single fasting insulin sample.
A clinician may examine insulin and glucose together when the relationship between them is the question.
Inside this test
Before your sample
Follow the laboratory's overnight fasting instructions and arrange medicine timing with your prescriber. You will have a baseline sample and two timed samples after a measured glucose drink.
A fasting blood draw comes first, followed by the glucose drink and samples at each scheduled hour. At home the team returns for those samples. In Deira, allow for the initial draw and two hours after the drink.

Each insulin value belongs to one time point. The corresponding glucose response, symptoms and reason for testing determine what the changes mean.

Review the three insulin measurements in their time order with any paired glucose results and symptoms during the test.
Patient questions
Allow for the baseline draw and the full two hours after the drink. The measurements must be interpreted with the timing and corresponding glucose information.
Yes. This order specifies fasting, one-hour and two-hour insulin. Confirm separately which glucose measurements your clinician wants to compare with those levels.
Tell the collector the actual timing. A delayed sample represents a different point on the insulin response and may change how the series is interpreted.
