CombiScreen® urine test strips: Instructions for proper storage and use To ensure the effectiveness of CombiScreen® urine test strips, it is important to carefully follow the storage instructions. The test strips should always be stored in a cool, dry environment. Storage at temperatures around 230°C is recommended. Be sure to close the container immediately after removing a strip to protect the remaining strips from moisture. It is also important to keep the test strips out of direct sunlight and not to refrigerate them. Treatment of urine samples When performing a urine test, only well-mixed and uncentrifuged samples should be used, and these should not have been stored for more than four hours. First morning urine is preferred. To ensure sample quality, the sample should be protected from light. If you cannot perform the test immediately, store the sample at a temperature of 24°C.
