How do I order?

FirstStepDx PLUS should be ordered by a doctor or other healthcare provider (physician assistant, nurse practitioner) for an individual with clinical features of autism spectrum disorder or other disorders of childhood development.
 

The FirstStepDx PLUS® collection kit includes a Test Requisition Form/Informed Consent and buccal (cheek) swab with sample collection instructions. Completed kits can be sent to Lineagen by FedEx. Phlebotomy (blood draw) kits are also available and include prepaid FedEx labels.

For collection kits and support, please submit a request online or call us at 888.888.OPEN (888.888.6736).

FirstStepDx PLUS Test Requisition Form/Informed Consent

Frontside: The blue (left) side of the form is for doctors/healthcare providers and the green (right) side of the form is for the parent/family to complete.

Backside: The back contains the informed consent, which families should review with the ordering provider or with a Lineagen genetic counselor by telephone.

Sample Collection

Each collection kit includes one buccal (cheek) swab. A buccal swab is an easy and painless way to collect cells which contain DNA that can be used for FirstStepDx PLUS genetic testing. In addition to easy collection, there are scientific advantages to using DNA from buccal swabs as well (Sdano, et al., 2014). The collection process takes only a few minutes and should be done at least 30 minutes after the patient has had anything to eat or drink.

  • Step 1: Remove the buccal swab from the pouch. Be careful not to touch the swab tip with your hands or fingers. Place sponge comfortably in mouth and rub inner cheek 10 times back and forth.
  • Step 2: Repeat rubbing motion on the opposite side of the mouth.
  • Step 3: Holding the tube upright, unscrew the cap from the tube. Be careful not to spill the liquid in the tube.
  • Step 4: Turn the cap upside down, insert the sponge into the liquid and close tightly.
  • Step 5: Invert the capped tube and shake vigorously 10 times.

The team at Lineagen will usually receive the kit within 2-4 days via FedEx. If needed, call us to schedule a FedEx pickup. At that time, a Lineagen representative will contact the family to review the billing policy based on each patient’s specific insurance plan and will offer genetic counseling by telephone.
