Several factors are involved in determining how long oxymorphone is detectable in the body, including which kind drug test is being used. Oxymorphone - also known as Opana, Numorphan, Numorphone, biscuits, blue heaven, blues - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting oxymorphone in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time oxymorphone will show up on a drug test.

How long oxymorphone has been taken, how frequently and how much can also play a role in how long the medication will show up on a drug test.

The following is an estimated range of times, or detection windows, during which oxymorphone can be detected by various testing methods:
