Can alchohol tests detect alchohol in system after three days?

Standard alcohol tests, such as breathalyzers and blood tests, typically detect alcohol in the system for a few hours to a day at most. However, certain tests, like urine tests, can sometimes detect alcohol metabolites for up to 48-72 hours after consumption, depending on various factors including the amount consumed and individual metabolism. In most cases, alcohol itself is unlikely to be detectable three days after consumption.
