This standard is proposed by the State Food and Drug Administration. This standard is under the jurisdiction of the National Technical Committee for Standardization of Medical Clinical Laboratory and In Vitro Diagnostic Systems.

Blood pressure monitoring systems are mainly used by non-professionals as external diagnostic medical devices. When used correctly, they can help diabetic patients monitor and take measures to control the concentration of glucose in their blood. The main purpose of this standard is to meet the requirements of blood pressure monitoring systems designed for use by non-professionals to obtain acceptable results when the user has received appropriate training, the instrument has been properly maintained, and it has been operated in accordance with the manufacturer's specifications and quality control procedures. This standard specifies the procedures for verifying the performance of blood glucose monitoring systems. This standard describes the general technical properties of self-testing blood glucose monitoring systems, which mainly refers to the information provided by the manufacturer, including the label and instructions for use of the self-testing blood glucose monitoring system. Since the test system is for non-professionals, the information provided by the manufacturer should be clear and easy to understand so that users can understand and correctly follow the operating procedures to perform self-testing. At the same time, appropriate warnings or prompts should be provided to guide the appropriate measures to be taken when abnormal results occur. This standard provides detailed provisions for the information provided by manufacturers.

5.4.2.1 Test samples
Should be obtained by epidermal acupuncture, such as fingertip, to collect a few different capillary blood samples. The range and number of samples are shown in Table 4. The exclusion criteria, such as blood pressure, should be based on the manufacturer's instructions for use. Sample collection, treatment, disposal and, in some cases, sample handling should be carried out in accordance with the instructions for use. Note: In some cases, a second blood sample may be collected to ensure that the sample is completely separated. 2: The capillary blood sample can be separated according to the method in 5.a> to obtain a capillary blood sample with a minimum blood pressure. 5.4.2.2 Test procedure
First, the capillary blood sample is divided into two equal parts. One of the two equal parts is tested for blood glucose using a blood analyzer according to the standard test procedure on the manufacturer's plate. The other equal part is tested using the two blood samples according to the manufacturer's method. If the test part can only be used to test plasma samples, add the manufacturer's coagulant to one of the equal parts and collect the plasma by centrifugation at 1 or 10 rn. Then, the blood plasma is tested according to the manufacturer's standard measurement procedure. The difference between the whole blood/plasma test result of each blood test strip and the whole blood/plasma test result of the reference analyzer is the deviation.
5.5 Batch Difference of Blood Glucose Test Strips
Use two blood test strips of different batches to measure 30 grams of fresh anticoagulated whole blood or quality control material on a blood glucose meter, and calculate the mean deviation of the two test results. To calculate the total mean of the test results of all three batches, the batch difference is calculated according to the formula ().
