TRUE METRIX Control Solution Bundle with TRUEplus Log Book is designed for people with diabetes who rely on consistent, accurate blood glucose monitoring to support everyday decisions. This bundle is an essential part of your blood glucose testing routine and works exclusively with TRUE METRIX Blood Glucose Test Strips. Our control solutions are meant for use for practice to ensure your testing technique is good, when opening a new vial of test strips, if results seem unusually high or low, if a vial has been left opened or exposed to extreme heat or cold or humidity, whenever a check on performance of the system is needed, and if meter damage is suspected (meter was dropped, crushed, wet, etc.). The bundle also has an included log book, which allows you to conveniently record daily blood glucose results, track insulin and medication doses, and add personal notes. TRUE METRIX products are made by Trividia Health, a trusted name with 40 years of experience in producing high-quality blood glucose monitoring supplies. Accuracy is confidence-and confidence starts with the right tools.
