The East Asian carrier screen includes 95 genes reported to have an increased carrier frequency in the East Asian population, such as USH2A (Usher syndrome, type 2A), SLC12A3 (Gitelman syndrome), and SLC26A4 (Pendred syndrome). Genes with known founder mutations in the East Asian population like SLC25A13 (citrin deficiency), ATP7B (Wilson disease), and GJB2 (non-syndromic hearing loss) are also covered by this panel.
Our carrier screening technologies are >95% accurate. A negative test result for any given disease does not exclude an individual from being a carrier for that disease, but only reduces the risk of being a carrier. The patient may still have a pathogenic variant that was not identified by this testing. Please refer to the residual risk table to determine the risk following a negative result.

- Blood: Two 5-10 mL EDTA tubes (lavender top), and either a third 5-10 mL EDTA tube or one 5-10 mL ACD tube (yellow top)
- Saliva: Saliva specimens are accepted in Oragene DNA (OG-500) kits by DNA Genotek. Please note that Tay Sachs enzyme analysis cannot be performed on saliva
- If carrier screening was previously performed through Sema4, reanalysis and/or test enhancements may be ordered without providing an additional specimen. Please contact the laboratory to determine if an additional specimen is required
- Ship at room temperature
- 10-14 days from receipt of specimen
