Providing patients with information they need to make informed care decisions.

Why is Pediatric Microarray Analysis so Important?

Microarray analysis is a type of genetic test used to look at a person’s chromosomes to detect changes in the amount of genetic information (or DNA).  Changes in the amount of genetic information, such as missing or extra pieces of a chromosome, may cause medical conditions or health problems including birth defects, delays in development, learning difficulties, autism, or other health issues. 

Results from our pediatric microarray test may help to determine whether your child’s health problems are caused by a chromosome condition. This information can be helpful for several reasons:

  • Discovering a genetic diagnosis can help your child’s doctor in deciding how to best care for your child.
  • Your child’s doctor may be able to test for other health conditions associated with genetic test results.
  • Your child may become eligible for services at school, such as physical or speech therapy.
  • It may be important for you to know whether there's a genetic cause for your child’s medical problems when considering future pregnancies or the health of other family members

When Might My Doctor Recommend A Pediatric Microarray Analysis?

Pediatric microarray testing is recommended by the American College of Medical Genetics (ACMG) for individuals with one or more of the following:

  • Developmental delays
  • Intellectual disability
  • Birth defects
  • Unusual physical features
  • Autism or Autism Spectrum Disorders (ASD)

How is Pediatric Microarray Analysis Performed?

The pediatric microarray analysis requires a sample of your child’s DNA.  This can be obtained by either a collecting a small sample of blood from your child’s arm or by using our Buccal Swab Kit to obtain a small sample of saliva.  

Test results are typically available within 8-10 days. Your doctor will review the results with you and answer any questions you might have..
