The Expanded Carrier Screen panel of 39 genes includes 23 genes highlighted in ACOG Committee Opinion 690: Carrier Screening in the Age of Genomic Medicine. It also includes 16 additional higher-frequency genes associated with conditions such as Duchenne muscular dystrophy, autosomal recessive polycystic kidney disease, and congenital disorder of glycosylation, type 1A.
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.
For prenatal samples, please contact our laboratory at 800-298-6470 for more information.
- Blood: One 5-10 mL ACD tube (yellow top) and two 5-10 mL EDTA tubes (lavender 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
