Detailed Answer:
Hi xxxxxxxxxx,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Percocet contains acetaminophen 325 mg and oxycodone 5 mg. Oxycodone is an opioid analgesic and is looked for in the drug test.

2. Oxycodone has a half life of approximately 3 to 5 hours. Medical information shows that 8% to 14% of the dose is excreted as free oxycodone over 24 hours after administration.

3. If you take the medicine as recommended then the drug test sample drawn will show the presence of oxycodone on Tuesday.

I consider that by passing the drug test you mean a positive oxycodone in the test result. Please correct me if I am wrong.

Hope your query is answered.
Please do write back if you have any doubts.

Brief Answer:
Your doctor will not know if you took 1/2 of 10-325 percocet

Detailed Answer:
Hi xxxxxxxx,
Thanks for writing back with an update.

1. If you take 1/2 percocet 10-325 then it is equal to 5 oxycodone and 162.5 acetaminophen.

2. Drug test will look for oxycodone only and therefore your doctor cannot make out any difference if you take 1/2 10-325 or one 5-325 percocet

3. The acetaminophen is not considered for drug testing.

Hope your query is answered.
Please do write back if you have any doubts.
