Low fetal fraction on first blood test

  I just got a call from the doc that the fetal fraction of the sample drawn 3 weeks ago was too low and wouldn't work.  We'll try again at my appt. next week and they also want to take a swab of my husband's cheek to send to the lab.  Anyone else not get a result on your first screening of genetic testing due to low fetal fraction?
