Limitations

Insulin, 30 Minutes may exhibit cross-reactivity with certain insulin analogs, such as insulin aspart, glargine, and lispro. Insulin detemir exhibits approximately 50 percent cross-reactivity, while insulin glulisine shows minimal reactivity. These factors can affect interpretability in contexts involving these analogs. Hemolyzed specimens and certain blood tube additives like heparinized plasma can adversely affect results.
