1. A biochemical reaction test strip tube comprising a tube portion and a cover portion wherein the cover portion comprises:
a cover portion lowermost side;
a cover portion inner bottom surface; and
a cover portion outer wall having a cover portion outer wall circumferential surface, and wherein the tube portion comprises:
a tube body comprising a tube body outer wall, a tube body inner wall, a tube body uppermost side, a first chamber and a second chamber wherein the tube body inner wall comprises a tube body inner wall circumferential surface, and wherein the first chamber has a first chamber top and the second chamber has a second chamber top;
a limit unit disposed at the tube body outer wall;
a biochemical chromatographic test strip having a biochemical chromatographic test strip end and disposed in the second chamber, wherein the chromatographic test strip end includes a sample absorption pad;
a first plurality of fitting members disposed on the tube body inner wall circumferential surface and along an axial direction of the tube portion; and
wherein
the cover portion further comprises a second plurality of fitting members disposed on the cover portion outer wall circumferential surface and along an axial direction of the cover portion, wherein either at least one fitting member of the second plurality of fitting members is connectable to the tube portion such that, when connected, the cover portion seals off the tube portion or at least one fitting member of the second plurality of fitting members is connectable to at least one fitting member of the first plurality of fitting members such that, when connected, the cover portion is fitted with the tube portion and seals off the tube portion whereby the first chamber top communicates with the second chamber top, and the biochemical chromatographic test strip end is close to the cover portion inner bottom surface, and one fitting member of the second plurality of fitting members located at the cover portion lowermost side is connected to one fitting member of the first plurality of fitting members located at the tube portion uppermost side.
