l was wondering if anyone knows how long first morning urine will be good stored in a cover cup to use on pregnancy tests.
l need to store it because first morning urine has the highest concentration of HCG. If you pee later in the day, it wo not be as concentrated. l just need to store it long enough to be able to run to the store. l know that you can store and have it be good for something like 24 hours but l was not sure. l guess you guys do not know. l will try looking somewhere else.
