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

Expert:  Dr. David replied 6 months 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 6 months ago.
would it be highly positive or just barely? 50/50 doesnt give me much confidence
Expert:  Dr. David replied 6 months ago.

it could be barely just positive.

Customer: replied 6 months ago.
is there anything I could use as an excuse? does it help that it was 12 days?
Customer: replied 6 months ago.
also the total number of beers was 5, not 5 beers each day
Expert:  Dr. David replied 6 months 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 6 months ago.
really. That was what I was hoping to get from you. Advice about what would have been better.
Expert:  Dr. David replied 6 months 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.
