Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Indicators can react with specific components in blood samples to produce color changes, making the results more intuitive and easy to read. Through the depth of color change, indicators can help accurately measure the concentration of certain components in the blood.

[0040] Stabilizers can protect biological enzymes and other sensitive components from inactivation during storage and use. By inhibiting microbial growth and chemical degradation, stabilizers help extend the shelf life of blood test materials.

[0041] Surfactants can improve the surface properties of blood test materials, making it easier for blood samples to be evenly distributed on the materials. They help to improve the contact efficiency between various components in blood samples and test materials, thereby increasing reaction speed and detection sensitivity.
