It really depends on the dose of alcohol, the specific sensitivity/cut-off for the test, and the type of test (EtG, EtS or another biomarker).

Generally, the range of detection is in the 1-3 day range. Most people are negative by 26 hours following moderate alcohol use.

With the additional information - you are asking about detection at 5 days. This is beyond the longest detection periods reported for the EtG tests. Your test should be negative on Wednesday if you had not alcohol beyond Friday night.
