Mama1619 I too went through something similar unfortunately I was not able to combats the PETH results through my attorney and lost thousands of dollars. Family Law Judges don’t want to hear the lack of evidence behind this testing modality. Best to remain abstinent and my recommendation is to donate blood prior to the PETH test. PETH is carried on red blood cells. The less you have the less PETH in your blood. But try to donate relatively close to the test so that your levels are still low.
Stay strong mama I know how hard this is. You’ll get through this.
