The invention discloses a portable urinalysis test paper capable of reducing interference. The urinalysis test paper comprises a substrate, test paper blocks arranged on the substrate, and isolation pads arranged among the test paper blocks, wherein the test paper blocks on the substrate sequentially comprise an ascorbic acid test paper block, a pH test paper block, a specific gravity test paper block, a protein test paper block, a glucose test paper block, a calcium ion test paper block, an occult blood test paper block, a urobilinogen test paper block, a bilirubin test paper block, a ketonebody test paper block, a creatinine test paper block, a leukocyte test paper block, a microalbumin test paper block, a nitrite test paper block and compensation pad arranged from one end of the substrate to the other end of the substrate. By optimizing the sequence of test strips and designing the isolation pads among the test paper blocks, the mutual interference is reduced; potassium iodate andsodium chlorate reagents are added into textured layers of the test paper blocks to reduce the interference of ascorbic acid, a reagent block for detecting the ascorbic acid is correspondingly added to serve as accuracy of the contrast inspection result, and thereby the influence of the ascorbic acid is reduced to the maximum extent.
