is characterized in that the reagent in the reagent kit 104 can be added to the reaction strip according to the set sequence by the liquid in the soft reagent package 104a under the action of the matched test instrument.

The upper case 101 is provided with a sample addition slot 101b communicating with the reaction strip 102, and can add a blood sample to a user.

Reaction strip 102 comprises chromatographic carrier 102a and absorbent paper 102b, and absorbent paper 102b is located the upper end that chromatographic carrier 102a kept away from liquid feeding hole 101a one side, can make things convenient for reagent to remove to absorbent paper 102's direction from the direction of liquid feeding hole 101a, then can wet chromatographic carrier 102a by a bigger area, convenient follow-up detection.
