I need information on amoxicillin. i have failed my drug test for cocaine and i do not use it am lost for an answer i have been only on amoxicillin
AskDocWeb: There are several sources that say Amoxicillin may test false positive for cocaine on urine drug screening assays (References: 13, 16, 18, 20, 21, 26, and 29). If you believe your test result is a false positive then it is in your best interest to get a confirmation test, preferably by an independent laboratory certified by the Substance Abuse and Mental Health Services Administration (SAMHSA).
I had a tetanus shot and tested positive for everything on a panel test..would the shot affect a drug test
AskDocWeb: The tetanus shot may cause pain at the injection site, dizziness, headache, seizures, muscle pain, joint pain, rash, nausea, and skin infections, but it does not show up on a drug test for drugs of abuse.
Fighting for custody
My son is very upset he is fighting for custody of his son. For over a whole year he has had to urine drug test for the courts. They have all been clean. He does not do any kind of drugs. Last month July he got called that he tested positive for methanphetamine. He is going crazy his son was to be placed with him on the 1st of Sept. In July he was taking a body building pill called Tri Methyl Extreme. Have you heard or have any infomation that could help us.
AskDocWeb: We suggest reading the fine print on the bottle. Some supplements say that you will fail a drug test while you are taking them. If you check the ingredients there are two in Tri Methyl Extreme that might cause a problem with drug tests:
13-ethyl-methoxy-gona-2 5 (10) dien-17-one
2a, 3a-epithio- 17a-methyl-5a-androstane-17 b-ol
Although we don't have data on those two ingredients, we are suspicious of any product that has "meth" as part of its name or listed in the ingredients. Hopefully a GC/MS confirmation test will be able to tell the difference.
Positive for Cocaine
My boyfriend has to take random UA's and he took three of them one after the other within two weeks. I have been with him everyday all day for the last two weeks and have taken him to take his UA's the last one that he took two days after taking his second UA he had to take a third and that one came back positive for Cocaine and I know for a fact that he has not been anywhere near any cocaine. How could he get a positive for a drug that he hasn't been around?
AskDocWeb: Okay, here are the possibilities as we see them:
t6633N SAP 10-50 GC/ms screen?
Will tramadol 1/2pill at 50mg show up in a t6633N SAP 10-50 GC/ms screen? Thanks.
AskDocWeb: Sorry Lorana, we have no data on that particular test. If they are testing specifically for tramadol then it will show up on GC/MS tests that are typically used for drug testing.
Do I have any rights?
I have been drinking coca tea for 6 months, due to a bad lower back operation. I also get morphine and vicodin from my pain doctor. He took a urine test and I was positive for cocaine. I assured him I was only drinking a tea. He refused to give me my pain medication and told me was going to send my test to a toxiology place. Can u please help me and tell me what can I do??. I really do need my meds. I dont want to go to the hospital for a shot. Do I have any rights? Thank you very much. He did not beleive that I was not using cocaine, he was very upset with me and told me he could lose his lic.
AskDocWeb: Patient's rights vary by State law so you may want to talk to a patient advocate. Check your local phone book to see if the Patient Advocate Foundation has a local office near you. You may not find them in the yellow pages but look in the business listings. They seek to safeguard patients through mediation assuring access to care and their services are typically free.
How does the GC/MS work?
I tested positive for amphetamines on an assay drug screen. They said they would send it out because of false positives. I do take Aldomet. The GC/MS test would rule out amphetamines if all I take is Aldomet correct? How does the GC/MS work?
AskDocWeb: You are correct. The GC/MS stands for Gas Chromatography-Mass Spectrometry. A part of your sample vaporized into a gas and a spectroscopic analysis is done on the components of that gas. The color spectrum of the substances when combined with its specific mass is somewhat like a fingerprint for each substance since each one has a unique spectrum.
False positive for cocaine!
Hi my name is Rosalind and I need some answers see I had a hair tox screening done on 7/30/12. We just got the results back and it showing a false positive for cocaine! Why I haven't used cocaine in almost 5 mths now? I need to understand why this would happen? The only medication I'm on, on a daily basis is Subutex? Can subutex or Suboxone been known to cause a false positive????
AskDocWeb: Subutex (buprenorphine hydrochloride) has not been reported to show up as cocaine on urine drug screens. Scalp hair grows at a rate of about half an inch per month. Body hair typically show drug use over a six (6) month timeframe. A standard hair test covers 90 days, although longer time periods can be tested, depending on the length of the hair. If your hair was 2 ½ inches long that could show the use from 5 months ago.
I just got tested today for a bunch of different things, and I came up positive for methamphetamine. The only things I take are Ibuprofen for arthritis and I've been using Hydroxycut and Ab Cuts to lose some weight. I looked at the ingredients and didn't see anything strange except trimethylxanthine which is supposed to be some kind of caffine. Help me!
AskDocWeb: The name Trimethylxanthine was derived from the German word kaffee and the French word café, each of which means coffee. It is pronounced tri·meth·yl·zan·thine. Despite "meth" being a part of its name, it still just caffeine and does not affect the results of drug tests. If you believe that your test result was a false positive then we suggest you get a confirmation test from a different laboratory.
False positive for alcohol
I am perscribed loratab and tramadol and restoril the last few times i went to the dr the did the ua and never said anything about alchol and went i went back the said my test last time showed it i never ever drink why is this happening?
AskDocWeb: Depending on what kind of test they used, there are several possibilities. Please read the Advisory issued by the US Department of Health and Human Services. Although it is dated September 2006 it remains in effect today. It's only 8 pages and shows examples of possible sources of false positives for alcohol tests.
