Don't send blood before the beginning of march, the lab is not doing anymore blood test right now. They are searching for the direct test and hopefully will find it by the end of february.
Congrats on the newest member of your family!
I have a Fanconi dog and part of the reason he has done so well is because strip testing caught it early. I'm sure your B will be fine and live a long, healthy life. Do post photos. :)
