How long can you save FMU for and stillget an accurate result on an HPT?

Courtney,

I know I read somewhere last night that after 45 minutes, the hcg might start to break down.....let me check something for ya!

Thanks girls!! I wasn't able to make it to the store for an HPT to test with this am but I peed in a cup instead and thought I would run get a test. But if 45min is the case I better be running to the store very soon.

37. Can I still use pee that's been sitting in a cup for several hours? hCG (pregnancy hormone) does break down and dissipate from urine once it leaves the body. It has a half-life of 24 hours, meaning the total amount will be cut in half for every day it sits out. If you are testing very early when only a small amount of hCG is present to begin with, that half might make a difference (for example, 25 mIU/mL of hCG will be detected with any early pregnancy test. By the time that pee sits out for a day, it has only 12.5 mIU/mL left, and only a very sensitive test may detect it.)

However, most women aren't peeing in cups and leaving it around for days; most women just want to save their FMU (or other concentrated urine) to be used later in the day (may need to purchase an HPT, want to wait for darling dearest to get home from work, may pee in a cup out of preference and then get distracted by a toddler doing a serious number on the poor kitty before you get the chance to dip the test, etc. All very common scenarios.) A few hours is unlikely to make a serious difference in the amount of hCG in your urine, so it's fine to use older pee. Putting your pee in the fridge will also slow the breakdown of the hormone, but I will disavow all knowledge of this suggestion in the event that your husband is grossed out by its proximity to his leftover pizza.





Did you get a positive??? What's going on?

Thanks Sabina,
I will put it in the fridge and run get a test on my way to my scrapbook party. Then I will try to post my result with all of you this evening. Thanks for helping me out because I actually thought it was bad to put it in the fridge. Dh won't complain he's not even home this am.
