Would these cause a positive ETG test. Cetyl, Stearyl, Cetearyl alcohols. Panthenol, Phenoxyethenol, Butylene Glycol, Propanol, Propylene Glycol.?

Only ethanol makeEtG. Those compounds aren't metabolized to EtG. Food products (vanilla), hygiene products, mouthwash, or OTC medications (cough syrups) containing ethanol can cause EtG levels to exceed 100 ng/mL but not 500 ng/mL. If measurable ethanol is detected (greater than .04 gm%) in the urine & EtG is >250 ng/mL, or if EtG > 500 ng/mL, then this is very strong evidence that beverage alcohol was consumed.
Depends. If the test is specific for ethyl glucuronide (etg) then other alcohols will not give a positive test. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
