Oxycodone can be a relief to know that it can only be detected for a limited amount of time. Blood samples usually only show traces for about a day. The Saliva tests can show traces for 1-2 days, and the urine tests for 3-4 days. If a hair test is taken, it can show Oxycodone usage for a longer period of time, up to 90 days. There are many factors that can influence the time frames mentioned above, such as how often and how much oxycodone is consumed, current hydration levels, and individual metabolic rates. As a whole, the body is able to quickly process oxycodone. The body clears Oxycodone as it heals and returns to a normal state. This is especially important when people are utilizing pain management programs.
