Snow White
HPT was pure white today, just like it was two days ago.
When I lay yesterday's and today's HPTs next to each other it's pretty damned clear that the HPT from yesterday picked up something yesterday (pink, not gray, so it's not an evap line). I wonder if morning urine being slightly tainted with PIO suppository residue can screw up these tests?
When I used to work in the immunology lab many years ago, we'd be testing for the presence of a protein and find that some other protein molecules could also bind to the substrate just like the protein that you were testing for...that they had the same affinity for the substrate you were testing them with. Isolating out the desired protein was a bitch.
I wouldn't doubt if something in the PIO gets into urine and binds to the HPT area.
But the color change part doesn't make sense. That's a new complex that forms from the union of b-HCG and whatever the substrate is.
Damn.
Well, beta's on Tuesday. Three more days so I can move onto my MRI.

post a commentDamn, that's so cruel. I definitely don't think the PIO would have anything to do with the colour you saw yesterday. It is quite a bit early though and if you had for some reason a more diluted urine this morning it may not ave picked it up. Still. I know how you feel, hope is fading away but I think it would be worth investigating immuno-issues (I know your doc does not really believe in it but it's no harm in getting checked out). Lots of love and hope your way, Fran
I agree with Fran. It's still early. Also, my tests are always stronger in the afternoon than in the morning. Not sure why as I know it's supposed to be opposite, but there you go. Crossing fingers very hard.
Ugh. I hate hpt's so much and this is exactly why--they fuck with your head and who ever knows for sure what they mean anyway. The information on the box says they're supposed to be a certain sensitivity but then, in practice, who really knows because everyone's experiences are always so different. And then you have to worry about bullshit like evaporation lines too. I'm sorry. Here's hoping for a nice clear line tomorrow morning.
