The invention discloses a siphon test paper, which pertains to the technical field of bio-sensor. The substrate of the test paper is printed with a working electrode, a reference electrode, an electrical circuit and an interface port connected with a read-out instrument. The working electrode and the reference electrode are composed of carbon coatings which are printed on the substrate at once and printed with a reaction working coating, the components by weight percentage include: 12 to 16 percent of enzyme, 15 to 20 percent of a conducting medium, 10 to 20 percent of an adhesive and 42 to 60 percent of buffer. Two sides of the reaction coating are bonded with a double-sided adhesive layer which is adhered with a hydrophilic membrane that is convenient for sucking sample blood and can limit the quantity of sample blood. The invention applies a screen printing method to produce the siphon glucose test paper at high speed and on large scale. The quality indexes of the test paper such as repeatability and precision further can limit the quantity of samples owning to the improvement of the sampling and introduction structure of the test paper, thereby improving quality and greatly reducing production cost. Raw materials applied can be obtained from various resources, processing is simple, technique maneuverability is strong and the test paper is suitable for large scale industrial production. Once the test paper of the invention sucks human blood, results can be read out conveniently and visually from a corresponding matching testing instrument.
