need to know if oxycodone is in any way related to oxymorphone. Does oxycodone break down in the system and then throw out oxymorphone chemicals like my doctor told me or is my urine test flawed like I believe it to be. There is no way I could have either one of these in my system yet my doctor (who really does not want to treat pain by medication only due to lack of payment by insurance company) tells me that the oxymorphone in my system is actually a chemical breakdown from the oxycodone. Comments or actual accurate knowledge anyone?
Oxycodone and oxycontin are broken down into predominantly nor-oxycodone and oxymorphone which is detectable in the urine. One can detect the parent compound (oxycodone or oxycontin) and the metabolites (nor-oxycodone and oxymnorphone) in the urine or just the metabolites. With that said, many of the new expanded opiate urine tests are using very low thresholds to deem a urine specimen positive and have arbitrarily lowered the GC-MS confirmation level to be commensurate with the immunoassay screening test. The usual GC-MS cutoff for opiates at the lowest level is for most opiates 300 ng/ml. However, labs such as Quest are now using an extended opiate screening test that can detect 100 ng/ml and are using GC/MS cutoff points of 100 ng/ml. Although these tests are getting more and more sensitive for drugs, the specificity is unknown. Thus they are able to detect a very small amount of oxymorphone with a high sensitivity but the specificity (or number of false positives) is unknown. There are currently no NIDA or SAMSA guidelines on cutoff values for oxycodone or oxymorphone as there is with codeine,morphine, and other narcotics and the labs are coming out with super sensitive tests without regard to how specific these tests are and can use cutoff values they establish. There needs to be an established cutoff value with which values above will be deemed positive and values below will be deemed negative. As it is, laboratories can use any value they want. With the recent news that pharmaceuticals can be found in tap water it is of paramount importance that these values be set to guide medical professionals and employers as to what constitutes a positive urine test for narcotics
The same thing happen to me which was that I was taking oxycodone and the doctor made me take a drug screen and it came back positive for oxymorphone and they told me that i could not come to that clinic anymore and was wondering how that I tested positive for oxymorphone when all i was taking was oxycodone... do you think i have a case....
This tells you whats up... 93% of people prescribed oxycodone test positive for oxymorphone.
Woodstock your a moron.. and drug stores rarely make mistakes considering everything is double and/or triple checked.
Tom - Yes you do have a case. The clinic had both wasted your time and money. Sadly I know more about the medications and their effects/side effects than my doctor that specializes is prescribing them. The doctors dealing with pain medications should be required to meet higher standards. They should know everything about the drugs they are prescribing and be updated accordingly to new information regarding the drugs. Your doctor screwed up for sure Tom.
