Hello, hope i am not too late to share with you this information.
Inside KKH, there is a dept call AMC. They are offer paranoma test at $800 - $900. There is option to pay extra to scan for some other stuff i think they call it micro deletion to rule out some rare but nasty stuff. Not sure how much more to pay though. Maybe your quote of $2K is inclusive of these microdeletion. No harm give them a call to compare price, afterall, i believe both place will also be sending your blood sample to USA for analysis. 10 to 14 days wait for result according to KKH AMC.
All the best
Oh ya, according to KKH AMC, Paranoma is 99% accurate, they have another test that cost about $300-$400. This test comprise of a scan + blood test. This cheaper test accuracy is 90%. Although the accuracy is lesser but it include a scan which i thought is also impt & good to have. Just in case you ask, for some strange reason, they do not have an option for you to do paranoma + scan.
