Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Expert:  Dr. David replied 23 days ago.

drinking 5 beers over 2 days 10 days ago has about a 50/50% chance of causing your PETH test to be positive.

Customer: replied 23 days ago.
would it be highly positive or just barely? 50/50 doesnt give me much confidence
Expert:  Dr. David replied 23 days ago.

it could be barely just positive.

Customer: replied 23 days ago.
is there anything I could use as an excuse? does it help that it was 12 days?
Customer: replied 23 days ago.
also the total number of beers was 5, not 5 beers each day
Expert:  Dr. David replied 23 days ago.

yes, I know

it is not a lot of beers

so 50/50 chance

best thing next time is to not drink any beers before your test.

Customer: replied 23 days ago.
really. That was what I was hoping to get from you. Advice about what would have been better.
Expert:  Dr. David replied 23 days ago.

you can focus on drinking more water and exercising and urinating more frequently

but PETH is not affected by your metabolism.

there are no ways known to affect a PETH test.
