The test card holder 30 is slidable on the housing 10 relative to the housing 10 such that the test card holder 30 can carry the test card 200 and onto the test card holder 40. The detection card detection seat 40 is used for generating excitation light to detect the detection card 200 and form a detection signal. The test device 100 may also include a processor (not shown) to control the sliding of the test card carrier 30 over the housing 10 and to control the test card carrier 40 to test the test card and to receive test signals and process the test signals to form diagnostic data.

Referring to fig. 4 and fig. 5, fig. 4 is a schematic structural diagram of the test card 200 according to an embodiment of the utility model, and fig. 5 is a schematic structural diagram of the test card 200 according to another embodiment of the utility model. The test card 200 is also referred to as a molecular diagnostic centrifugation test card or test card. The test card 200 may include a body 201 provided with a sample tube, a flow channel, a waste chamber, a separation tube, and a reagent tube. The body 201 is made of a rigid material such as plastic or the like. The body 201 may be a plate-like structure as a whole.
