Glucose Test Strips Types and Their Use

Glucose Test Strips are a feature of most diabetic peoples lives, the need to check blood glucose levels is critical in the management of a diabetic's condition. Strips depend on measuring conductivity through a minute sample of blood taken by the diabetic from a local site with a lancet.

Understanding the reaction that occurs on the strip once the minute blood sample is placed there by user

The proper name for the strips is Electrochemical blood glucose test strip (EBGTS). Indeed this name summarises how the strips work. An electrochemical reaction occurs between the blood sample and the chemical in the strip. A number of different chemicals can be used, but essentially they all work similar. On some strips, glucose oxidase is used, risk of oxygen interference with the sample can affect the reliability of this method and the currents sent to the meter.

Dehydrogenase is used in various forms, it has the benefit of not reacting in the same way with oxygen. Some forms of it do not react with maltose and their use is being phased out. Ensure that the glucose test strip you use or intend to use is capable of measuring non glucose sugars.

An electric current or charge is passed between two electrodes and measures the current or charge. The current or charge level will vary depending on the glucose level and this is transmitted and computed into the figure you read off the test meter.

As can be seen from above glucose test meters and strips vary in the way they measure the glucose level. Rigorous testing is done to ensure error factors are eliminated or minimized. Most modern meters will give an error result if the blood sample is insufficient.

Calibration of meters and strips has became automated and most strips will now incorporate a code which adjusts the meter. Accuracy is maintained by rigorous testing at the manufacturing stage and the removal of any glucose test strips that do not meet the rigorous quality and test standards laid down.

Use should only occur after consultation sell test strips with your medical adviser and follow their recommendations regarding strips and glucose test meters. Use articles such as this to inform yourself and be in a position to ask pertinent questions about the glucose test strips they recommend.
