Understanding Your Results

Results indicate the presence or absence of alpha thalassemia mutations in the fetus. A positive result means mutations were detected, suggesting the fetus may carry the trait or be affected, requiring further consultation.
📊

Mutation not detected

No alpha thalassemia mutations identified in the fetus; low risk of thalassemia alpha trait.

📊

Mutation detected

Alpha thalassemia mutations found; fetus may be a carrier or affected, depending on parental mutations.

📊

Inconclusive

Results unclear; repeat testing or additional genetic counseling may be needed.

⚠️ When to Consult a Doctor:

Consult a doctor if results are positive or inconclusive, or if there are concerns about fetal health, for appropriate management and genetic counseling.

Limitations

  • ⚠May not detect all rare or novel mutations
  • ⚠Requires accurate parental genetic information
  • ⚠Results are probabilistic and may need confirmatory testing

Risks & Considerations

  • ●Minor risks from blood draw, such as bruising
  • ●Rare risks from amniocentesis, including infection or miscarriage

Interfering Factors

  • ●Sample contamination
  • ●Improper sample handling or storage
  • ●Inadequate sample volume
