Understanding Your Results

The Microarray 750K test results are interpreted by a clinical geneticist. A normal result indicates no significant chromosomal abnormalities, while an abnormal result may show deletions, duplications, or other variations that could be pathogenic and require further evaluation.
📊

Normal

No pathogenic copy number variations detected, suggesting no major chromosomal abnormalities

📊

Abnormal

Pathogenic CNV identified, which may be associated with genetic disorders; genetic counseling and further testing recommended

📊

Variant of Uncertain Significance

CNV detected but clinical significance is unclear; correlation with clinical findings and family studies needed

⚠️ When to Consult a Doctor:

If the test results are abnormal, if there are concerns about genetic disorders, or if you have a family history of genetic conditions, consult a geneticist or the referring physician for further evaluation and management.

Limitations

  • ⚠Cannot detect single gene disorders
  • ⚠May not identify balanced chromosomal rearrangements
  • ⚠Variants of uncertain significance may be reported

Risks & Considerations

  • ●For blood draw: minor bruising, pain, or infection at the puncture site
  • ●For amniocentesis: small risk of miscarriage, infection, or amniotic fluid leakage
  • ●For chorionic villus sampling (CVS): risk of miscarriage, infection, or limb defects in rare cases

Interfering Factors

  • ●Sample contamination
  • ●Improper sample handling
  • ●Maternal cell contamination in prenatal samples
