Question

Once opened, test strips are good for 180 days and control solutions are good for 90 days or until manufacturer's printed expiration date whichever comes first. True or False?

Answer 1

The statement regarding the lifespan of opened test strips and control solutions is true, as these products have a limited shelf life to ensure accuracy of results due to the sensitivity of the chemical reagents they contain. They revolutionized glucose monitoring, a concept developed by chemist Helen Free.

Step-by-step explanation:

The statement that test strips are good for 180 days and control solutions are good for 90 days or until manufacturer's printed expiration date, whichever comes first, is a True general guideline for the use of these products in glucose monitoring and other similar tests. It is important to follow these guidelines because the chemical reagents on the test strips can degrade or change over time, which could lead to inaccurate results. It's also crucial to pay attention to the proper read time for the test strips to avoid false-negative or false-positive results which is related to the kinetics of the reaction taking place on the test strip pad. Chemist Helen Free was instrumental in developing this technology that significantly simplified glucose monitoring for people with diabetes.
