I was a heavy drinker for months and quit 23 days ago and haven't had anything. I have a PETH test tomorrow and want to know if I can do anything to lower it. I read that I can give blood and that might help. I have a double red blood cell donation set up tomorrow at 2:15 and have to get the PETH test done by 4:30. Will this do any good? I also wanted to know if drinking lots of water or lemon juice can help to clean out the liver and maybe give better results. Any advice on this would help. Also does working out help to clean out the system.

I have had high blood pressure and low red blood cells. I also had elevated liver enzymes, but now they are back to normal.

I also have some OCD, anxiety and germaphobia and use hand sanitizer sometimes like 50 times a day as I'm an uber eats driver and I'm constantly touching doors and different stuff in restaurants so when I get back in the car I usually squirt some on my hands to sanitize them. Can that effect the results any? I also read that using red wine vinaigrette can effect the results. Is any of that true?

Even if I was drinking up to 18 hard seltzers a day before that for a few months and haven't drank in 23 days will I show postive or negative on a PEth test?

Will Donating double red blood cells help to lower anything with new blood cells being made? Will the red blood cells be recreated that fast if I only have a couple of hours between donation and the test?

I'm really glad I'm not drinking anymore, but I'm worried my past will show up on the test. I quit drinking on Jan 6th. Is there anything I can do to cleans myself more today before I have to do this test this afternoon?
