Pediatric diagnostic testing

Genetic insights on developmental issues and disabilities

Sometimes, a child may be born with intellectual disabilities or developmental conditions that that were not detected during pregnancy, becoming evident only after birth, or when the child’s development seems delayed. In some cases, the intellectual disabilities or developmental conditions are genetic. Uncovering the reasons for these conditions can often help parents and pediatricians provide better care for the child.

Reveal® SNP Microarray can analyze chromosomes for changes that can explain certain birth defects, intellectual disabilities, and autism spectrum disorders.

Reveal SNP microarray is an advanced technique that makes it possible to examine a patient’s chromosomes and allow for the detection of smaller changes in the amount of DNA.1,2

In addition to detecting small gains or losses of genetic material, Reveal SNP microarray can also show if a pair of chromosomes came from just one of the patient’s parents or whether a patient’s parents are closely related.1,2 These events may explain certain genetic disorders.1,2,3


Other testing options

In addition to diagnostic tests, we offer: noninvasive prenatal testing (NIPT) and serum screening for Down syndrome and other conditions; carrier screening for disorders such as cystic fibrosis; and hereditary cancer screening.
