but you still have to have someone order it. Even when I qualified for two family members to get free testing based on my results the family members had to go to someone in their state to get the order.
i just checked Nebula. they actually have a sale at the moment. I missed the one around thanksgiving and have been watching for it to happen again. it’s $100 bucks off right now for the deep version of the test at $199. Usually it costs $299. dont know how long it will last. You do have to pay a subscription fee but if you have got a situation where you need this the subscription fee is peanuts
If you are just curious you can do 23andme version that gives you some analysis of your genes and upload the raw data to prometheus and get their analytics. I will warn you...deciphering the variations and what they mean is a challenge for a variety of reasons. You can do 23andme with a fake name
