A point-of-care testing (POCT) fully-automatic chemiluminescence device based on a multi-channel parallel pretreatment technology includes a support. The support is provided thereon with a reaction chamber assembly, which reciprocates linearly relative to the support. A multi-channel parallel pretreatment assembly and a photomultiplier tube (PMT) assembly are arranged on the support and are located above the reaction chamber assembly. The multi-channel parallel pretreatment assembly is configured to transfer, clean, and separate reagents in reagent strips in the reaction chamber assembly. The PMT assembly is configured to detect a luminescence value of the cleaned and separated reagents. The device does not have a liquid passage, resulting in low maintenance costs and high reliability. This realizes automatic sample addition, supports whole blood testing, and avoids carry-over. The device solves the problems in the traditional POCT chemiluminescence device of manual sample addition, cumbersome steps, and human errors which are easily made.
