Sample collection instructions regarding fasting are included in each sample collection kit, which must be read before collecting any samples. Oral fluid testing requires collection between 6 am and 9 am, with no eating one hour before and no drinking 30 minutes before collection.

Can I order Cyrex tests for children under the age of 15?

Yes, however, there are some stipulations:

  • Not all draw centers have the equipment and/or staff to conduct blood draws for children. We recommend that you call the center to see if they can conduct pediatric blood draws.
  • Due to circumstances beyond our control, pediatric blood draws are not included under Cyrex’s contracted phlebotomy. All patients 15 years of age and younger are included in the pediatric group. Pediatric blood draws must be scheduled by the parents at a laboratory of their choosing. A draw fee may be required. Back to top
