1. Strip: Remove the test device from the sealed pouch, put the end of the test strip print with arrow.into the specimen (about 50-60μl), the interface of urine should not exceed the MAX line, take it out after 5s and place the test stripe on a clean and level surface.
Cassette: Take off the outer packing, put the cassette onto the desk with the sample window up.Drop 3 drops of specimen (100μl) vertically into the circular groove of cassette.
2. Observe the test results immediately within 5-10 minutes, the result is invalid over 10 minutes.
Storage
Store as packaged in the sealed pouch at 4-30°C, avoid hot and sunshine, dry place, valid for 24 months.
