I Had Been Taking Oxycodone N Oxycontin For Approx 2

I had been taking oxycodone n oxycontin for approx 2 weeks. Taking my last light dose on Sunday, Before returning to work I was sent for a urine test the following Friday afternoon, 5 days no usage. I was drinking 2 to 3 gallons of diet ice tea everyday since to flush out. My urine at test was extremely pail yellow, minor tint of yellow.. Will my usage appear in a urine sent to a lab in Pennsylvania??
