Low pricing aside, the physical steps in the process seem relatively easy. The "spit kits" themselves are manufactured by OraSure Technologies, Inc. with a unique barcode and then sent directly to consumers who have paid the $99. The kits are then shipped (presumably by the consumer) directly to Laboratory Corporation of America (LabCorp) for processing. LabCorp, in turn, is contracted to use the Illumina HumanOmniExpress-24 format chip for actual genotyping. These results are then electronically transmitted back to 23andMe where (based on the barcode) they are then matched to the consumer account created during the sign-up process.
This chip seems like a lead. 'Google of DNA'

I still see no connection to Sergy however.
