Far from confused. I'm glad you can offer this advice to others with a clear conscience. It is up to others to evaluate the risk for themselves.
If you think there is no difference between the test I get from a pharmacy in the US and the test the Thais administer then you are quite an optimist. However, somehow I doubt it. More like you don't like to be called wrong, no matter who suffers on account of it.
Jared Jernegan Not true. Depends on the test. If you can have a false positive with never having had the virus, you could certainly have inconsistent results from test to test if having recently had the virus. In addition folks say it can take 90 days to get back to reliably negative results. It sounds like he will be well short of that time.
Considering the consequences of testing positive in Thailand and the inconsistent enforcement of policy, this would be a real nail-biter in my opinion.
