Understanding Your Results

Results from the Chromofic Karyoarray Test are interpreted by clinical geneticists to identify chromosomal abnormalities. Normal results indicate no detectable imbalances, while abnormal results may specify a syndrome or genetic condition, guiding further clinical actions.
📊

Normal

No pathogenic chromosomal imbalances detected

📊

Abnormal

Detection of gains or losses in chromosomal material, potentially indicating a specific syndrome

📊

Variant of Uncertain Significance (VUS)

Genetic change found with unclear clinical impact, requiring further evaluation

⚠️ When to Consult a Doctor:

Consult a healthcare professional if you or a family member experience symptoms such as developmental delays, recurrent miscarriages, or have a family history of genetic disorders, to discuss if this test is appropriate.

Limitations

  • ⚠May not detect all genetic disorders, such as single-gene mutations
  • ⚠Potential for variants of uncertain significance (VUS)
  • ⚠Cannot detect balanced translocations or low-level mosaicism

Risks & Considerations

  • ●Minor bruising or soreness at the blood draw site
  • ●Rare risk of infection or fainting

Interfering Factors

  • ●Poor sample quality or hemolysis
  • ●Insufficient blood volume
  • ●Contamination during collection or transport
