Principle and method of the procedure used for examinations
The Roche Accu Chek method for measuring blood glucose is based on novel enzyme technology and
microelectronics. When whole blood is applied to the strip, electrons are produced by the conversion of
glucose to gluconolactone by the enzyme glucose dehydrogenase and the coenzyme PQQ. The electrons are
transferred through a mediator, potassium ferricyanide. The resulting current of electrons is proportional to
the glucose level in the blood. This dynamic process is monitored by the sensor and is translated into
accurate glucose readings.
Patient preparation
Wash the test site with soap and water before taking the sample.
Do not perform testing on patients:
(a) on intravenous vitamin C (Ascorbic acid >0.17mmol/L) preparations (IV Pabrinex)
(b) with Triglyceride concentrations > 20.3 mmol/L
(c) with Galactose concentrations > 0.83 mmol/L
Capillary blood glucose sampling should not be performed on patients with impaired peripheral circulation
(i.e.: Dehydration, shock, diabetic ketoacidosis (DKA), decompensated heart failure & peripheral arterial
occlusive disease.). Such patients should have venous/arterial blood drawn and tested on the glucometer.
Type of sample, container and additives
Whole blood from capillary, venous or arterial samples may be used.
Required equipment and reagents
1. Accu Chek Inform II meter - The POCT team will configure the Accu Chek Inform II meter prior to
initial use.
The meter automatically records: the time and date of test, the Identification Data for the operator,
patient and samples, the control solution and test strip information and the test results and comments.
Battery Pack
The meter contains a rechargeable battery pack and begins charging as soon as the meter is docked
in the base unit. Meters must be returned to the docking base unit for recharging when the Battery
Low warning is displayed or at least once in a twenty-four hour period.
Always turn off the meter before removing the battery pack.
Wireless Network Connection
The meter contains an RF card for a wireless network connection which allows the meter to send
data (patient ID, operator ID and test results) to the data management system without the need to
return the meter to the base unit.
2. Base unit
Status display window at the right hand side of the base unit will light up when the power supply is
connected: blue if connected via WiFi, green when hardwired and red if there is an error.
