This means your urine test was sent for both qualitative and quantative testing. A positive/negative result but also confirmation you are taking meds exactly as they are prescribed. From your post, it seems you may not be if you are ‘running short’. Patients have a responsibility to take the meds exactly as prescribed, not more, not less , UNLESS and UNTIL you have gotten your drs consent BEFORE taking more.
I don’t know how often you are supposed to take the Percocet per day- how many tablets/per x hrs, but it is likely the results will be lower than they should be given your dosing schedule. The 2634 nanograms/per milliliter of urine is a measurement of how much Percocet was present in one milliliter of urine.
