📝 Before testing, the sample should be restored to room temperature (20–30°C) and cut into pieces of about 1 cm. Weigh 2.00±0.05 g of the sample into a 15 mL centrifuge tube, then add 3 mL of extraction solution, close the lid, vortex or manually shake up and down for 1 min, let stand for 1 min, and obtain the test solution. Note: After sample pretreatment, spotting should be completed within 5 min.

🧪 Test Procedure

before the experiment, Before the experiment, please read the instructions carefully. Before use, bring the test card and microwell reagent to room temperature (20–30°C). Remove the test card from its original packaging and use it immediately after opening. After taking out the required microwell reagent, immediately close the reagent bucket lid to prevent moisture. Use a micropipette to take 100 μL of the test solution into the microwell reagent, slowly aspirate (2–3 times) to mix thoroughly with the reagent in the microwell. After incubation at room temperature (20–30°C) for 3 min, use a pipette to draw 100 μL of the mixed solution and vertically drop it into the sample well (S well), or use the disposable dropper provided in the kit to draw the mixed solution and slowly add 3 drops vertically into the sample well (S well). Start timing when the liquid begins to flow. React for 10 min, then interpret the result according to the schematic diagram. Readings taken at other times are invalid.
