What will oxycodone test positive for

Adherence can be masked by dilute urine, time since ingestion, quantity ingested, or the laboratory's established threshold limits. Discussing adherence with the patient is helpful, but testing for a particular medication may be necessary to resolve issues of diverting the prescribed medication.

Negative results in a dilute urine specimen make interpretation problematic. The director or toxicologist of the reference laboratory can serve as a valuable resource if questions arise. The concentration of a drug in urine depends on several factors, including time since use, amount and frequency of use, fluid intake, body fat percentage, and metabolic factors.

There are many ways for patients to circumvent testing. These include adding adulterants to urine at the time of testing, urine dilution through excessive water ingestion, consumption of substances that interfere with testing, and substitution of a clean urine sample.

Several chemicals can be added to a urine sample to interfere with urine drug testing. Household chemicals, including over-the-counter eye drops containing tetrahydrozo-line; bleach; vinegar; soap; ammonia; drain cleaner; and table salt, can produce a false-negative test.

A variety of commercial products that are available online may also be used. Some substances are detectable because of changes they produce in the appearance, specific gravity, or pH of the urine. Dilution of the urine through excessive water consumption or diuretics can decrease the urine drug concentration and make a negative test result more likely. Therefore, excessively dilute samples should be rejected. In situations where observed voiding is mandated, urinary substitution techniques and devices can be quite sophisticated and difficult to detect.

An artificial penis with an electronic, temperature-controlled urine reservoir can be purchased online. Patients may attempt to evade detection by voiding before testing, then refilling their bladder with clean urine using a catheter. Federal testing procedures will catch some, but not all, tampering attempts. Summaries of the most important factors are listed in Tables 3 16 and 4. Remove anything in the collection area that could be used to adulterate or substitute a urine specimen.

Request the display and removal of any items in the patient's pockets, coat, hat, etc. Require all other personal belongings e. Instruct the patient to wash and dry his or her hands preferably with liquid soap under direct observation and not to wash again until after delivering the specimen. Place a bluing agent in the commode and turn off the water supply to the testing site.

Information from reference Unusual appearance e. Information from references 15 and The CMRO is a physician who is responsible for receiving, reviewing, and evaluating results generated by employers' drug testing programs. The CMRO is also responsible for the accuracy and integrity of the drug testing process by determining whether there is a legitimate explanation for unexpected test results and protecting the confidentiality of the drug testing information. When performing non—legally mandated tests, physicians should be familiar with the specific drug screening statutes and regulations in their own state.

State regulations might address chain of custody requirements, patient privacy, which specimens may be screened, and how results may be used or shared. Reference laboratories routinely offer medical review officer services and telephone consultation with a laboratory toxicologist. When in doubt, the rules and best practices of the U. Department of Transportation provide a legally defensible framework for most jurisdictions. Already a member or subscriber? Log in. Interested in AAFP membership?

Mar 1, Issue. Urine drug screening can enhance workplace safety, monitor medication compliance, and detect drug abuse. C 10 An extended opiate panel is needed to detect commonly used narcotics, including fentanyl Duragesic , hydrocodone Hycodan , methadone, oxycodone Roxicodone, Oxycontin , buprenorphine, and tramadol Ultram. C 10 Appropriate collection techniques and tests of specimen integrity can reduce the risk of tampering.

Who Should Be Screened? Behaviors that Raise Suspicion of Drug Misuse or Dependency Taking a controlled substance for a long period of time new patients Refusing to grant permission to obtain old records or communicate with previous physicians Demonstrating reluctance to undergo a comprehensive history, physical examination, or diagnostic testing especially urine drug screening Requesting a specific drug often because of the higher resale value of a brand name Professing multiple allergies to recommended medications Resisting other treatment options Other aberrant behavior: Issuing threats or displaying anger Targeting appointments at the end of the day or during off hours nights or weekends Giving excessive flattery Calling and visiting a physician's associates Repeatedly losing a prescription Requesting a dose escalation Demonstrating noncompliance with prescription instructions Demonstrating other evidence of alcohol or illicit drug misuse.

These screenings test for a variety of drugs, such as marijuana and cocaine , as well as opioids. Drug screenings may be used for:.

You may need opioid testing if you are currently taking prescription opioids to treat chronic pain or another medical condition. The tests can tell if you are taking more medicine than you should, which can be a sign of addiction. You may also be asked to take a drug screening, which includes tests for opioids, as a condition of your employment or as part of a police investigation or court case. Your health care provider may also order opioid testing if you have symptoms of opioid abuse or overdose.

Symptoms may start as lifestyle changes, such as:. Most opioid tests require that you give a urine sample. You will be given instructions to provide a "clean catch" sample. During a clean catch urine test, you will:. In certain instances, a medical technician or other staff member may need to be present while you provide your sample.

During a blood test , a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.

You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. Be sure to tell the testing provider or your health care provider if you are taking any prescription or over-the-counter medicines. Some of these may cause positive results for opioids. Poppy seeds can also cause a positive opioid result.

So you should avoid foods with poppy seeds for up to three days before your test. There are no known risks to having a urine or saliva test. There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. Although physical risks to testing are very small, a positive result on an opioid test may affect other aspects of your life, including your job or the outcome of a court case.

If your results are negative, it means no opioids were found in your body, or that you are taking the right amount of opioids for your health condition. But if you have symptoms of opioid abuse, your provider will probably order more tests.

If your results are positive, it may mean that there are opioids in your system. If high levels of opioids are found, it may mean you are taking too much of a prescribed medicine or otherwise abusing drugs.

False positives are possible, so your health care provider may order more tests to confirm a positive result. Learn more about laboratory tests, reference ranges, and understanding results. If your results show unhealthy opioid levels, it's important to get treatment. Opioid addiction can be deadly. If you are being treated for chronic pain, work with your health care provider to find ways to manage pain that don't include opioids.

Treatments for anyone who is abusing opioids may include:. The information on this site should not be used as a substitute for professional medical care or advice. Contact a health care provider if you have questions about your health.
