What's this test for?

This test is ideal if you're trying to understand the genetic cause behind developmental delay, intellectual disability, dysmorphic features, or congenital differences. It's also useful if a child has been diagnosed with a pervasive developmental disorder and you want to know whether a specific chromosomal change is responsible. Many families use this test to get answers when other basic genetic tests haven't found a cause.

What happens after I get my results?

Your results will be available in your account, with an explanation of what each finding means and how it compares to typical genetic patterns. If a copy number variant or unusual genetic region is found, the report will explain its significance, and next steps may include testing parents to see if the change was inherited or new. You can download the full lab report directly from your account at any time. Because this is a one-time genetic test rather than a fluctuating biomarker, ongoing trend tracking is not typically needed, but your results remain saved in your account for future reference.

What's included in this test?

This test uses ClariSure® Oligo-SNP chromosomal microarray analysis to detect aneuploidies (extra or missing whole chromosomes), deletions, duplications, and long continuous regions of homozygosity across the entire genome. Analyzing the whole genome this way matters because many genetic conditions are caused by tiny gains, losses, or rearrangements of genetic material too small to see under a microscope with standard karyotyping. This approach also identifies long stretches of matching genetic material inherited from both parents, which can point to certain inherited conditions. This test can also be run on parents to determine whether a copy number variant found in a child is inherited or occurred new (de novo).

How can I naturally support a child's development while awaiting genetic answers?

While you wait for results, focus on consistent routines, early intervention therapies (like speech or occupational therapy), and a balanced diet to support overall growth and brain development. Regular sleep schedules and reduced screen time can also support developmental progress in young children. These steps don't replace genetic answers but can help support day-to-day development in the meantime.

When will I get my results?

Results are typically ready within about 7 days after your sample is received at the lab. Genetic testing like this requires detailed laboratory analysis, so the turnaround is longer than a standard blood test. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

This test is often considered for children with unexplained developmental delay, intellectual disability, unusual physical features, or multiple congenital anomalies. It's also appropriate for parents of a child with a known genetic variant who want to find out if they carry the same change. Families building a more complete picture of a child's health history may also find this test valuable.

What symptoms may indicate a chromosomal microarray could help?

Signs that this test might be useful include delayed speech or motor milestones, learning difficulties, distinctive facial features, slow growth, or multiple birth differences appearing together. Repeated, unexplained medical issues in a child can also be a signal. If several of these are present without a clear cause, this test can help identify an underlying genetic explanation.

What is a chromosomal microarray and why does it matter?

A chromosomal microarray is a lab test that scans a person's entire set of chromosomes for very small missing or extra pieces of genetic material. It matters because these tiny changes can affect development, learning, and physical health, and they're often too small to detect with older genetic tests. Finding a clear genetic cause can guide care decisions and help families understand what to expect.

What does it mean if a copy number variant is found?

A copy number variant means a piece of a chromosome is either duplicated or missing compared to what's typical. Some of these changes are harmless variations that don't cause any problems, while others are linked to developmental or health conditions. The lab report will explain whether the specific variant found has been associated with any known condition, and testing parents can show whether it was inherited or appeared new in the child.

How often should this test be repeated?

This is generally a one-time test, since a person's chromosomal makeup doesn't change over time. Retesting isn't usually necessary unless there's a specific reason, such as testing additional family members to trace inheritance. If new symptoms develop later, further genetic evaluation may be considered separately.
