- Hemolyzed or clotted samples
- Insufficient sample volume
- Incorrect labeling or missing information
Understanding Your Results
Normal
No pathogenic variants detected, indicating low risk for VWD based on this gene.
Carrier
One pathogenic variant detected, may indicate carrier status for autosomal recessive types.
Affected
Two pathogenic variants detected for recessive types or one for dominant types, confirming VWD diagnosis.
Variant of Uncertain Significance (VUS)
Genetic variant found but clinical significance unknown; further testing and monitoring recommended.
If symptoms of bleeding disorders persist, worsen, or if genetic counseling is needed for family planning or management.
Limitations
- ⚠May not detect all possible mutations in the VWF gene
- ⚠Requires genetic counseling for proper interpretation
- ⚠Not suitable for prenatal diagnosis without specific clinical indication
- ⚠Results may be variants of uncertain significance (VUS)
Risks & Considerations
- ●Minor bruising or pain at the blood draw site
- ●Rare risk of infection or fainting
- ●Psychological impact of genetic results
Interfering Factors
- ●Sample degradation or contamination
- ●Technical errors during sequencing
- ●Insufficient DNA quality or quantity
