Testing on Friday is too late as you probably wouldn't get results until early the following week. Test on Thursday for Friday result. then determine where to go.
Test on Friday morning, send out Friday morning, if you can get the results back Saturday a.m. Otherwise you'd have to wait. Monday is Labor Day. If you do test on Tuesday you won't get results until Wednesday. That's cutting it a little too close for me. Good luck.
I got same day results. So I knew exactly what was going on. I would check with the vet's office to see if they get same day results and test accordingly.
I agree, I would test Thurs. for Friday. You get a shipment Sat. That might be the best you can do. Whatever that number is, you might ask for a shipment Tues. for Wed. bet she will be ready about Mon/Tues. of next week.
Make sure the tech knows to use a red top non separator tube. This is important with progesterone and I have had to point it out to techs who had no idea.
