Urine Drug Test Metformin

I keep testing positive for barbituates and i don't do any type of drugs except for my diabetic prescribed drugs metformin and glipizide. How is this possible. ## I take metformin 500 my. Twice a day am I going to test positive for drugs because of the metformin??? ... My brother had a urine test and was told he had traces of drugs as in Benzodiozine. He takes Metformin, Bezalipmono, and Simvastatin. Please someone tell me if Metformin is the cause? This is urgent as may jeopardise his job! Thank you. ## If you got a false positive for benzodiazepines (like Xanax or Valium) whoever did the test should have send it to a lab for a GC/MS confirmation. It would probably be best to get a consult from and medical review officer MRO. An MRO is a doctor trained to interpret drug test results and say what might be causing a false positive. Was the test a urine dip test like you can find at the store. If so it definitely should have been sent to a lab for GC/MS confirmation. GC/MS is the "gold standard" for any type of drug testing. ... recently i went for a urine drug test to be hired for a job, i forgot to tell the drug tester i am diabetic and my medication is glucovance 5/500 i have not recieved word from the job and am growing concerned my medication gave my test bad results. my question is will the diabetic medication glucovance 5/500 have an effect on my urine drug test? ## Neither the Gluburide, nor the Metformin in Glucovance are known to cause false positives on drug tests. However, if you are having any type of kidney problem, that could cause false positives. Where you taking anything else? ... I recently took a urine drug test for a new job. The technician tested the urine with some kind of strip and told me that it was present of opiate, they are sending the urine Continue reading >>

Prescribed Medications And Potential False-positive Urine Drug Screens

Prescribed Medications And Potential False-positive Urine Drug Screens

A comprehensive literature review was conducted for all medications on the formulary of Bedlam Clinic, a free evening clinic for the medically indigent or working poor, offered by the University of Oklahoma School of Community Medicine in Tulsa. The English-language literature was reviewed, utilizing databases for Ovid MEDLINE, International Pharmaceutical Abstracts, the Excerpta Medica Database, the Cochrane Database of Systematic Reviews, ACP Journal Club, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Health Technology Assessment Database, and NHS Economic Evaluation Database. The search strategy was developed by a medical librarian combining the terms false positive results, urine, and substance abuse testing and the generic names of 116 medications. When possible, MeSH terms were used and expanded upon. Truncation was employed for a maximum number of results. In addition, the references for each medication with a reported false-positive UDS were reviewed. Reports of false-positive UDS results were found for 25 (21.5%) of 116 formulary medications. The potential for false-positive UDS results was identified for the following medication classes on the clinic formulary: antihistamines, antidepressants, antibiotics, analgesics, antipsychotics, and nonprescription agents. Specific immunologic reagent tests have been identified with these reactions, and, in some cases, the concentrations needed to elicit the reaction were provided. Examples of specific medications with false-positive reports are listed in Table 1 and included brompheniramine,[ 6 , 7 ] bupropion,[ 8 , 9 ] chlorpromazine,[ 10 , 11 ] clomipramine,[ 10 ] dextromethorphan,[ 1214 ] diphenhydramine,[ 11 , 15 ] doxylamine,[ 16 ] ibuprofen,[ 14 ] naproxen,[ 4 ] prome Continue reading >>

Can Disease Or Illness Show A False Positive On Drug Tests?

Can Disease Or Illness Show A False Positive On Drug Tests?

Imagine this: you are sitting in a doctor’s office waiting for the results on a urine drug screen you took a few minutes ago. It could be the longest 5 to 10 minutes in your life if you consumed something to be worried about. If you didn’t take anything, then you don’t have anything to worry about, right? Well in that rare case that you may pop positive for an illegal drug, sometimes it really isn’t your fault and this positive test maybe a blessing in disguise. This might be a good time to ask your doctor about performing tests for Diabetes, Kidney issues, or for Liver problems. Sometimes, body chemistry may play a role in your “false positive” results because of a buildup of chemicals in your body due to the fact that you may have problems with the way you metabolize chemicals. The truth is that if you have Kidney Infection, Kidney Disease, Liver Disease, or Diabetes, you could get a false positive for THC (Marijuana), Amphetamines, Opiates, Ecstasy, & Cocaine on your drug test. That’s not because of medication; the false positive comes from the body chemistry stemming from these diseases and you may not even know you have it. This is one of the reasons why it’s always a good idea to get a Lab Confirmation or an MRO to look at the sample and results. Some people may find out that they have a life-threatening illness, such as Multiple Sclerosis, may after getting a “false positive” urine drug test simply because there are similar chemicals in the body that test positive for Cocaine, Opiates, and Heroin. Obviously, you can’t make a diagnosis on just a urine drug test alone, but it’s enough to get you to talk about it with your doctor and maybe perform some other tests to make a diagnosis. What could be the scariest part is if the person has never Continue reading >>

If you're on a medication and not sure you're not going to test positive during a random drug test. Please look at the following pieces of information that may help you save your job. The next time you see the doctor ask for a note stating that your Doctor has prescribed the medication and how long have you been taking it? You will need to present evidence you have been taking the prescribed or self-medicating over the counter (OTC) medicine. Invoke Wyngarden Rights and ask for a witness or a Union Official to be present during the conversation. Record the conversation date and time when you informed the tester that you may fail the test. Do not disclose what you are taking to management, you don't need to inform them. Once taking a test contact your doctor to talk with them about any medication may cause a positive. The following drugs have the potential for a false positive on a drug test. Amitriptyline. This is a tricyclic antidepressant used for chronic pain, neuropathy (nerve pain), depression, and migraine prevention. Amitriptyline may lead to a false positive urine test for the hallucinogenic drug LSD (lysergic acid diethylamide). Bupropion (generic Wellbutrin). Used as an antidepressant, for weight loss, and smoking cessation, bupropion may lead to a positive screen for amphetamine, methamphetamine, and LSD. Dextromethorphan. Found in Robitussin, Delsym and other over-the-counter cough suppressants. If you've taken a medication with dextromethorphan in it, your drug screen may be positive for opiates and PCP (phencyclidine). Diltiazem (Cardizem) is used for hypertension (high blood pressure) or to slow your heart rate if you have atrial fibrillation. If you're taking diltiazem your urine drug screen may test as a false positive for LSD. Diphenhydramine (Benadryl Continue reading >>

Drugs That Can Cause False Positive Drug Tests

Drugs That Can Cause False Positive Drug Tests

Getting a new job or adopting a child are two reasons why you may be required to have a drug test. These tests typically examine a sample of urine for the presence of alcohol, marijuana, amphetamines, benzodiazepines, barbiturates, phencyclidine (PCP), cocaine, lysergic acid diethylamide (LSD) or strong painkillers called opioids. But urine drug tests are not perfect and many prescribed and over-the-counter drugs can yield a false-positive test. This is especially likely if the drugs or their breakdown products have a chemical structure that is similar to the tested drugs. Drugs that may cause false-positive urine drug tests include certain antibiotics, cold medicines, psychiatric medications and painkillers. Video of the Day One of the most common antibiotics, amoxicillin (Amoxil), can cause a false-positive test for cocaine. Quinolones, a group of antibiotics including ofloxacin (Floxin), levofloxacin (Levaquin) and ciprofloxacin (Cipro), may produce false-positive tests for amphetamines and opioids. Rifampin (Rifadin), an antibiotic frequently used to treat tuberculosis, can also lead to a false-positive result for opioids. A false-positive LSD test may occur in people taking the antibiotic cephradine (Velosef). Ephedrine and pseudoephedrine, ingredients often found in decongestants or cold medicines, can cause a false-positive test for amphetamines. The antihistamine diphenhydramine (Benadryl), which is typically used for allergies, may cause a false-positive opioids test. Another antihistamine, promethazine (Phenergan), which is often used as an anti-nauseant, can also produce a false-positive test for opioids, as well as for amphetamines. Diazepam (Valium), a common anti-anxiety drug, can cause a false-positive result for alcohol. Another anti-anxiety medication, Continue reading >>

Ask The Expert: False Positive Amphetamine Urine Screens

Ask The Expert: False Positive Amphetamine Urine Screens

Question: What can cause a false positive urine drug screening for amphetamine? Urine drug screenings are useful diagnostic tests. In chronic pain management, drug testing can assess the appropriate intake of drugs, help with the diagnosis of substance abuse, and improve drug management.1 Screening for illicit drugs, including amphetamine, can be useful in assessing and monitoring patients with chronic pain. It is important to consider the potential for false positive results when the results of urine drug screenings for amphetamines are interpreted. Urine screenings for amphetamines commonly involve the use of immunoassays. Multiple immunoassays are available, and they all share similar basic methodology. In these tests, a sample of urine or bodily fluid is added to a solution containing antibodies or immunoglobulins, which bind to targeted analytes. By interacting with specific structures, the immunoglobulins signal the presence of certain drugs.2 Immunoassays frequently are used in initial urine drug screenings because they provide rapid results, cost relatively little, and are commercially available. However, false positives are possible and must be considered when interpreting results. Immunoassays often lack the specificity to target individual drugs and typically screen for structurally related compounds. Immunoassays for amphetamines can detect several related chemicals, including methamphetamine, 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA), and methylenedioxyethylamphetamine (MDEA), that share a common structure that includes a phenyl ring and an amino group connected by a two-carbon side chain.3 However, these structural elements also can be found in other non-amphetamine drugs as shown in Figure 1 (below), and this may result Continue reading >>

These 15 Medications Can Cause A False Positive On Drug Tests

These 15 Medications Can Cause A False Positive On Drug Tests

We hear “false positive” as a defense from professional athletes all the time when it comes to drug screens—but unexpected results on drug screens really do happen. A urine drug screen tests for the presence of certain illegal drugs and prescription medications. You may be more likely to be tested when applying for a job than when playing professional sports, but you could also be affected by a false positive. Here are several common medications—prescription and over-the-counter—that you’ll want to be aware of as potential culprits for a false positive. Amitriptyline. This is a tricyclic antidepressant used for chronic pain, neuropathy (nerve pain), depression, and migraine prevention. Amitriptyline may lead to a false positive urine test for the hallucinogenic drug LSD (lysergic acid diethylamide). Bupropion (generic Wellbutrin). Used as an antidepressant, for weight loss, and smoking cessation, bupropion may lead to a positive screen for amphetamine, methamphetamine, and LSD. Dextromethorphan. Found in Robitussin, Delsym and other over-the-counter cough suppressants. If you’ve taken a medication with dextromethorphan in it, your drug screen may be positive for opiates and PCP (phencyclidine). Diltiazem (Cardizem) is used for hypertension (high blood pressure) or to slow your heart rate if you have atrial fibrillation. If you’re taking diltiazem your urine drug screen may test as a false positive for LSD. Diphenhydramine (Benadryl). Many over the counter remedies contain diphenhydramine, an antihistamine also used as a sleep aid, including Tylenol PM and Advil PM. If you’ve taken these, you could test positive for methadone or PCP. Ibuprofen and naproxen (Advil/Motrin and Aleve). Two very common over the counter anti-inflammatory pain medications.

Could this combonation of medication cause the positive result? AskDocWeb: There is a possibility that it could but only on the urine drug screen. The confirmation test would eliminate that false positive. My nightmare started last yr 3-17-10 i took a pre-employment test and was told I tested positive for cocaine on hairtest but urine test was fine. I refused to let them retest me cuase of lady at company came to me in a very suspicious way. I wouldn't pay for them to retest me cause I told them I don't smoke drink or do drugs. Your lab made grave error. I got retested the next month at another lab and results were negative like it supposed. Plz note diabetes didn't cause falsepositve cause there was an excessive amount of BZE present other than cocaine amount found. So I feel you pain and I've lost so much but the bad thing about it I live in Texas and I haven't found lawyer willing to take case yet. That is the sad part of this whole ordeal the lab was wrong.

False-positive Interferences Of Common Urine Drug Screen Immunoassays: A Review

False-positive Interferences Of Common Urine Drug Screen Immunoassays: A Review

Immunoassays dominate urine drug screens (UDSs) because they are simple to use, easy to automate and provide rapid results (1). Unfortunately, they are subject to cross-reactivity with structurally related and unrelated compounds potentially yielding false-positive results. Further complicating the issue are the many available platforms with differing cross-reactivities. Immunoassays for selected drug classes, e.g., opiates and benzodiazepines, are also subject to clinically important false negatives (2). False-negative results can be caused by a variety of factors including the cross-reactivity of the antibody used by the assay, the cutoff concentration for a positive result and length of time between drug ingestion and specimen acquisition. False negatives are not covered in this review but present opportunities for significant patient mismanagement if not understood. The best practice following a positive UDS involves confirmation with the mass spectrometry (MS) technique such as gas chromatography–mass spectrometry (GC-MS) or liquid chromatography–tandem mass spectrometry. Regrettably, MS testing is limited or nonexistent in many hospital laboratories. When confirmatory testing is performed, results are generally unavailable for several days. Owing to the delay in receiving confirmation results, decisions about patient care are frequently made on ‘presumptive positive’ drug screening results. Because many providers have limited knowledge of immunoassay cross-reactivity data, patients with false-positive results may lose eligibility in rehabilitation programs, be inappropriately terminated from employment or suffer from medical staff bias because of lack of trust (3). Although this topic has been reviewed previously (2–4), our aim is to provide a concise, c Continue reading >>
