[0030] The present invention provides a colloid osmotic pressure assay reagent pack, comprising a box body 1 and an upper cover 2. The box body 1 can be a rectangular parallelepiped box structure, but other shapes, such as a cylindrical box, can also be used depending on the situation. The box body 1 is closed at the lower end and open at the upper end with an opening. The upper cover 2 snaps onto the upper opening of the box body 1, forming a closed cavity structure within the box body 1. Multiple reagent bags 3 are installed within the box body 1, and the reagent bags 3 are loaded with different reagents, such as different cleaning solutions.
