Blood work....

I've had 3 consecutive miscarriages my insurance wouldn't cover any blood work till after the third. My last was in May 29th at 11 weeks 4 day, the furthest I've made it, my dr. Did put me on low dose asprin and progestin. I had blood work last week, they took 21 vials, and said it would take about 2 weeks for the results, they only took one vial from my husband. Has anyone had this type of blood work done, it's for genetic abnormalities and clotting disorders?
