Insulin, 60 Minutes
Also known as: INSULIN 60
Use
The Insulin, 60 Minutes test measures insulin levels in serum to evaluate the patient's insulin response following glucose intake. This test is valuable in assessing insulin secretion and could help diagnose or monitor conditions related to insulin resistance and diabetes. It provides information about how a patient's insulin levels respond within 60 minutes of a glucose challenge, typically performed as part of an oral glucose tolerance test.
Special Instructions
Not provided.
Limitations
The test may exhibit cross-reactivity with various insulin analogs. It reacts nearly equimolarly with insulin aspart, insulin glargine, and insulin lispro, whereas insulin detemir shows about 50% cross-reactivity. The test has negligible reactivity with insulin glulisine (<3%). Potential interference could arise from improper specimen handling such as hemolysis, or from unacceptable specimen types such as heparinized plasma and I.V./vitreous fluids.
