What are the precautions for performing a test with the UScreen Cup?
The UScreen Cup is for external use only. Do not use if the pouch is punctured or not sealed. The test cannot be used more than once—discard after first use. Do not use beyond the expiration date shown on the pouch. Keep out of the reach of children.
Users should follow the appropriate federal, state, and local guidelines concerning the frequency of assaying external quality control materials. There is an internal procedural control line in the test device termed the ‘Control Region’. However, the use of external controls is strongly recommended as good laboratory testing practice to confirm the test procedure and to verify proper test performance. Positive and negative controls should give the expected results. When testing the positive and negative control, the same assay procedure should be adopted.
