Abstract: A biochemical test strip tube comprises a tube portion and a cover portion. The tube portion comprises a solution chamber and a test strip fixing member which has a horizontal spacing between its outer edge and an inner wall of the tube portion. When the cover portion seals off the tube portion, a top of the solution chamber communicates with a top of the test strip fixing member, and a horizontal spacing is provided between an outer edge of the test strip fixing member and an inner wall of the cover portion. Due to the horizontal spacing between the test paper fixing member and the inner wall of the tube portion, the biochemical test strip does not contact or form a wall against the inner wall of the tube portion to avoid affecting the detection effect when the biochemical test strip is provided inside the test strip fixing member.
