1 Adhere to the instructions for test procedures. Do not run more than 8 tests at one time. 2 Store test kits at 2-8˚C when not in use, and do not use the kits beyond the expiration date. 3 Please don’t touch the membrane on the strips. 4 Remove the microwell sealer slightly to prevent the powder from being released from the wells. 5 The sample to be tested must be a homogeneous liquid that cannot be agglomerated, fermented, rancid precipitated, etc., and cannot be colostrum. 6 The sample should be thoroughly mixed with the reagents in the microwells to avoid foaming. 7 Avoid direct sunlight and direct blows during testing. 8 Do not reuse pipette tips, test strips, or microwells. 9 The unsealed microwells should be used within 1 hour. 10 Do not take tap water, distilled water, or deionized water as a negative control. 11 After incubation, be sure to immediately remove the sample pad at the lower end of the test strip and read the result within 1 minute because the color depth of the test strip will increase after drying, which affects the result
