I took about a shot on Friday and a swing on Saturday I did an ETG Monday morning at 8'oclock I weigh 140 should I be worried?

EtG/EtS are created in proportion to the amount of alcohol (EtOH) consumed. As EtOH is eliminated EtG remains. A by-product. Unquantified terms such as "swig" are of no help. The answer is also time dependent. When did you drink on Fri and Sat and the number of hours between last drink and time of test.
