Average savings compared to US prices
Advanced genetic testing that sequences all protein-coding regions of the genome to identify disease-causing mutations. China's genomics laboratories offer clinical-grade whole exome sequencing with comprehensive bioinformatics analysis at significantly lower cost than Western labs. Particularly valuable for undiagnosed genetic conditions, developmental delays, and rare diseases.
Genetic Counseling
Pre-test counseling explaining scope, limitations, and potential findings including incidental results and implications for family.
Duration: 1 hourSample Collection
Blood draw for DNA extraction, with parental samples collected for trio analysis if applicable.
Duration: 30 minutesSequencing and Analysis
Next-generation sequencing of all exonic regions with bioinformatics pipeline for variant calling and annotation.
Duration: 3-5 weeksResults Interpretation
Geneticist review of identified variants, clinical correlation, and detailed report with genetic counseling session.
Duration: 1-2 hours- Comprehensive screening of 20,000+ genes in single test
- Trio analysis with parents significantly improves diagnostic yield
- China's large genomic databases enhance variant interpretation
- 40-60% cost savings compared to equivalent Western testing
- Variants of uncertain significance may create diagnostic ambiguity
- Incidental findings may reveal unexpected health risks
- Negative results do not exclude genetic conditions
- Turnaround time of several weeks required for analysis
