3.TEST METHOD
| 1 | Use sample collection tube to collect, mix well and dilute the sample. Use sampling stick to take about 30mg of stool. Then, transfer the stool to a sample collection tube containing sample diluent, tighten by rotating, and shake sufficiently. |
| 2 | If stool of patient with diarrhea is loose, use disposable pipette to draw the sample, add 3 drops (about 100μL) of sample-to-sample collection tube, and shake the sample and sample diluent sufficiently. |
| 3 | Take the test device out of the aluminum foil bag, place it on a horizontal worktable flat, and make a proper mark. |
| 4 | Discard the first two drops of diluted sample. Then, vertically, and slowly add 3 drops (about 100μL) of bubble-Free diluted sample to the center of sample hole of the test device and start timing. |
| 5 | The result shall be read within 10-15 minutes. Test result obtained after 15 minutes is invalid (for detail about result see Interpretation of Test Results). |
