Unfortunately, : Unfortunately, genetic testing can take a little time - in some cases up to six weeks depending on the hospital or lab that is running the test. For a more accurate answer, you should call the doctor that sent the test. If they have experience with the genetic testing lab and this particular test, they can give you a better (and possibly shorter!) idea of how long it will take. Good luck to you!

Developmental delays: Self-injurious behaviors ; aggression are seen in many neurodevelopmental disorders. A genetic microarray ; a dna probe for fragile x help determine a genetic cause. See a developmental/behavioral pediatrician for evaluation for other causes ; to develop a multimodal treatment plan. Have a child find evaluation through your local school district for early childhood special education services.
