I used a laundry detergent Bold Laundry detergent that is on a website list claiming that it contains 1-5% alcohol content. a web site below makes claims that such detergent can cause false positives on ETG Alcohol tests.

can merely wearing clothes laundered in this detergent cause a false positive on an ETG urine test? Cut-off level 500 ng/mL?
