Understanding Your Results
Positive for pathogenic variant
Confirms diagnosis of CD19 gene immunodeficiency common variable type 3. Genetic counseling and targeted treatment recommended.
Negative for pathogenic variant
No mutations detected in the CD19 gene. Clinical correlation and additional testing may be needed if symptoms persist.
Variant of uncertain significance
Genetic variant identified but clinical significance unknown. Follow-up and family studies may be required.
Consult a doctor if you experience recurrent infections, low immunoglobulin levels, autoimmune symptoms, or have a family history of immunodeficiency. After receiving test results, discuss them with a healthcare provider for appropriate management.
Limitations
- ⚠May not detect all possible genetic variants or mutations
- ⚠Requires genetic counseling for interpretation
- ⚠Results should be correlated with clinical findings
Risks & Considerations
- ●Minimal risks from blood draw, such as slight pain, bruising, or infection at the collection site
- ●No significant risks associated with genetic testing itself
Interfering Factors
- ●Contaminated or degraded DNA sample
- ●Improper sample storage or handling
- ●Recent blood transfusions may affect results
