Oddball Question, how could you stop a Clearblue Digital pregnancy test result from fading away after 24 hours?

My wife and I had the pleasure of discovering she was pregnant.  We used the new ClearBlue digital pregnancy test which at first i though was gimmicky, but after realized how awesome it was.  We used several other non digital tests and the results were very faint.  Anyone new to this might be left wondering.  But, i digress... The Clearblue digital activates but having the test strip section dipped in urine.  As it wick ups the fluid it activates a "moisture sensor" of some kind, the test activates and you get a little animated digital hour glass.  After several minutes it will say "Not pregnant" or "Pregnant" followed by how many weeks your pregnant up to 6 weeks.  This was very clear and concise test, not squinting of the eyes.  The down side to this test though is that it only displays the results for about 24 hours, then disappears.  Yes I know its slightly bizarro to keep a pregnancy test, but... its one of those memory things.  Anyway, the question I put out is how to keep the test result from not disappearing?  Sure a larger battery capacity, perhaps with a redundant system built, thats the easy part.  Whats tricky is i believe the test strip.  Its most likely measuring a current drop or gain which is whats activating the test.  As it dries out, current is lost and the circuit ceases to work.  Or the saturated test strip corrodes the sensors, perhaps even the battery just dies after 24 hours, though this seems sketchy.  Any ideas would be great

I honestly doubt you'll ever forget she's pregnant......

Congratulations.

Of course not, the only way to explain would be my answer to Lemonie above.
 
That is one to REALLY embarrass your child with when they bring home a new boy/girlfriend.

Take a photograph of her when it's obvious.
These are disposable consumer-products; once you've had your moment that's it.
I'd hope that your wife would actually know herself if she was, why was a test important (genuine interest)?

Tricky one actually. Its a bit of a miracle that she became pregnant actually and in the next little while it will take another miracle to hold onto the child. It may seem trivial to hold onto something like that, but it may be the only tangible memory she may have. Of course we took photos, and they will do, but sometimes to hold something... its different somehow. This will be her second child.
Thanks for the comment, I think that I'd go with Steve's suggestion.

i would suggest not saving a used pregnancy test.
if this is your first baby, congrats.
pregnancy causes hormonal changes in woman that affect the smell of certain things especially down there. after a couple months in the drawer you will be throwing it out anyways. (the test.. not your wife)

When disassembling the unit all sections that came into contact with pee are simple to remove actually and pop out as a cartridge so all "smell items" would be gone. And you are right, my wife as is is a super smeller, so that would not be good

Put it in a canning jar along with some of the activating fluid and freeze it. It won't keep forever but frozen down to zero and below it will probably keep for years.

If you want even more fun you can also freeze a placenta. There are companies that are "harvesting" them for various reasons and they freeze them to keep them fresh.

Photograph it IN guess it fades because it dries out
Guess it doesn't dry out then.
You could print the bit of the screen and stick it over the real thing - who will know?

Yes, I photographed it minutes after taking the initial result knowing it would fade. Really trying to do this electronically, otherwise I would just print out the section of the photo showing the readout to scale and just slip it into the existing window of the tester
Buy another one, then work out how it holds the reading.

The sensor uses optical methods to detect the position of active regions on the test strip. http://en.wikipedia.org/wiki/Lateral_flow_test
