Understanding Your Results

Results indicate the presence or absence of PDGFRα mutations. A positive result confirms HES, while a negative result may require further testing.
📊

Positive

PDGFRα mutation detected, confirming hypereosinophilic syndrome. Consult an oncologist for treatment options.

📊

Negative

No PDGFRα mutation detected. Clinical correlation and additional tests may be needed to rule out HES.

⚠️ When to Consult a Doctor:

Consult a doctor if you experience symptoms like persistent fever, fatigue, or swelling, or if test results are abnormal.

Limitations

  • ⚠Test only detects PDGFRα mutations; other genetic causes of HES may not be identified.
  • ⚠Results should be correlated with clinical findings and other diagnostic tests.

Risks & Considerations

  • ●Minor bruising or pain at the collection site
  • ●Rare risk of infection with bone marrow aspiration

Interfering Factors

  • ●Sample contamination
  • ●Improper sample storage
  • ●Recent blood transfusions may affect results
