Can you store urine in a cup to use later that day for a pregnancy test?

By storing your HcG, you should cover it over in a cup and place it in the fridge. When you want to use the test, take it out of the fridge and let it warm to room temperature before testing.

BUT.. you can't use this urine after 7 hours of storage as the HcG in your urine will begin to break down. Keeping it in the fridge gives you a little more time, but eventually it becomes undetectable.
