mc22, the whole process costs around, US$ 800 is the fee of AABB approved laboratory M/s LabCorp for conducting DNA matching test (from Applicant in USA & the beneficiary in Karachi, Pakistan), it took a lot of time as it was time of COVID and the USA Embassies around the World were shutdown for a certain period of time.
Then, in Pakistan the Consulate at Karachi took around Rs.4000 as the Consultant fee for collecting DNA sample.
So, the total cost of DNA Sampling costs around US$850, and remember that i am talking about cost came about two years back. Hope this answers your query.
