Monday isn't bad, but it's not ideal. Weekend eating and drinking patterns can still affect some markers. Tuesday-Thursday are generally better for accuracy and faster processing.
Friday morning is fine. Avoid Friday afternoon as samples may not be processed until Monday, which could affect certain test results and delay your answers.
Tuesday, Wednesday, or Thursday morning. This gives you time to fast overnight, avoids weekend effects, and ensures quick processing before the weekend.
