1. Introduction

Product Name: Blood Glucose Test Strips (Supporting product: blood glucose tester)

Product Composition:

Generally, it consists of an electrode, a reagent, a protective cover film, and a PET substrate. The reagent is generally composed of an enzyme substance (glucose dehydrogenase, glucose oxidase), an enzyme protective agent, and a non-reactive component.

Working Principle:

1) Electrochemical method

pyrroloquinoline quinine

Electrochemical method uses the principle of detecting the current signal generated during the enzyme reaction to reflect the blood glucose level. The electrons generated by the reaction between the enzyme and glucose pass through the current counting device, read the quantity of electrons, and then convert it into a glucose concentration reading.

According to the enzyme used in the electrochemical blood glucose test strip, it is divided into two types: glucose oxidase (GOD) method and glucose dehydrogenase (GDH) method. GDH is also required to use different coenzymes in the reaction, namely pyrroloquinoline quinine glucose dehydrogenase (PQQ-GDH) and flavin adenine dinucleotide glucose dehydrogenase (FAD-GDH). And nicotinamide adenine dinucleotide glucose dehydrogenase (NAD-GDH).

2) Photochemical method

Photochemical method is to detect the color change of the test strip during the reaction to reflect the blood glucose level. The enzyme used in the blood glucose test strip is generally glucose oxidase (GOD), an intermediate (color-containing substance) produced by the reaction of the enzyme with glucose. After the reaction, the color of the test paper is changed, and the absorbance of the reflective surface of the test paper is detected by a detector, and the blood glucose concentration can be obtained according to Lambert-Beer's law.

Typical Structure:

1. Electrode receiving area: Insert the area of the machine and accept the current generated after the reaction.

2. Handheld area: Take the part of the test strip.

3. Reaction zone: The area in which glucose in the blood reacts with chemical reagents.

4. Inhalation zone: Place blood drops close to this area and blood can be automatically inhaled into the reaction zone.

2. Classification

Classification Code (IVD Reagent): II-2 Class II Reagent for sugar detection

Product Description: It is used to detect the content of glucose in human samples, which is mainly used to reflect blood sugar levels.

3. Registration Unit

Divided into the same registration unit:

1. The composition is the same and can include different packaging specifications (difference in the number of test strips);

2. Different packaging specifications (difference in the number of test strips) and applicable to different types of instruments;

Divided into different registration units:

1. The reaction enzymes of blood glucose test strips are different;

2. Applicable objects (adults/babies);

The calibrator and quality control can be registered with the blood glucose test strip or applied for registration separately. The same registration unit can contain only calibrators or control products, as well as calibrators and controls.
