This invention relates to the field of point-of-care testing devices, and more particularly to a microfluidic immunochromatographic reagent kit. It includes a chip shell and an external diluent addition component. The chip shell has a blood collection head at its front end, and a chromatography chamber for placing test strips inside the chip shell. The blood collection head communicates with the chromatography chamber through a microfluidic channel within the chip shell. The external diluent addition component is detachably connected to the front end of the chip shell and is used to add diluent to the chromatography chamber through the blood collection head and the microfluidic channel. The blood collection head collects blood samples. The microfluidic channel has a capillary structure to ensure that the blood sample is premixed with the diluent as it passes through the microfluidic channel, and to slow down the flow rate of the mixture into the chromatography chamber. With this invention, medical personnel only need three steps—"puncture-merge-observation"—to complete the operation and testing, requiring no professional training.
