Factors affecting the accuracy of blood glucose testing

The accuracy of blood glucose measurement is generally concerned with the quality and compatibility of blood glucose test strips and blood glucose meters. In fact, the sealing performance of the test strip barrel is also a major factor affecting the accuracy of blood sugar, so the purchase of test strip barrels for pharmaceutical companies is also very important. 

As a special blood glucose test tool, the test strip should be sealed and stored. If the bottle's tightness is not done well, the test strip in the bottle will easily deteriorate due to moisture, which will affect the accuracy of blood glucose measurement. The tightness of the test paper barrel is mainly considered from three aspects: the material of the packaging, the sealing effect of the bottle cap, and the water vapor transmission rate.

The bottle body of the test paper barrel is generally made of polypropylene, which has better gloss than polyethylene, and the finished product is more delicate, has good dielectric properties and high-frequency insulation, and is not affected by humidity. The bottle cap is made of low-density polyethylene with better toughness, which can achieve better sealing effect. To measure the tightness of the test paper bucket, you can take an appropriate amount of the test paper bucket, put a proper amount of glass balls in each bottle, screw the cap tightly, and place it in a container with an air extraction device, immerse in water, and vacuum to 27KPa and maintain 2 If there is no water or bubbling in the bottle, it is qualified.

The water vapor transmission rate of a medical plastic bottle refers to the water vapor transmission rate of a sample in a certain time under a specified temperature, relative humidity, and a certain water vapor pressure difference. According to the requirements of the test conditions, the amount of water vapor input per liter bottle of the test paper barrel within 24 hours shall not exceed 1000 mg.

Diabetes is a chronic disease. Patients need to adjust the dosage of hypoglycemic drugs at any time according to the results of daily blood glucose testing. The accuracy of blood glucose testing directly affects the patient's medication and health status. Pharmaceutical companies must not only strictly enforce the quality standards of test strips, but also attention should be paid to the tightness of the test strip packaging. Good packaging can make blood glucose test data more accurate.
