Seroquel
Date: 3/16/2012
Will seroquel show up as anything on a urine test that is sent off to the lab?

April

AskDocWeb: It is possible that Seroquel might show up as a false positive for amphetamines (See reference 48) on the initial urine screening but that would be eliminated when the sample was examined by the lab that does the confirmation test.

Saffron satiereal extract pr Relora?
Date: 3/17/2012
Will taking saffron satieral extract and relora cause false positives on my monthly drug test at the PO’S office? It gets sent to a lab.

Tracy

AskDocWeb: We have found no evidence to suggest that saffron satiereal extract (Crocus sativus) might cause a false positive on urine drug tests for drugs of abuse.

Relora is a weight loss supplement that consists mainly of two traditional Chinese herbs: Magnolia officinalis and Phellodendron amurense. We didn’t find any link between Relora and false positives on urine tests. However, you might want to go easy on the Magnolia officinalis. It contains aristolochic acid, which causes rapidly progressive fibrosing interstitial nephritis and renal failure. It is also linked to urothelial malignancy. Urothelial malignancy accounts for about 80% of all tumors of the urinary tract.

Lithium carbonate
Date: 3/17/2012
Can lithium carbonate cause you to fail a drug test or give you a false positive result.. thanks

Michael

AskDocWeb: Lithium interferes with birth control pills and may cause a false positive pregnancy test but does not show up on urine tests for drugs of abuse.

Methadone
Date: 3/18/2012
If I took just 1 methadone pill a day before I had a mouth swab will it showup?

Patti

AskDocWeb: The mouth swab tests that we evaluated do not test for Methadone (MTD). For example, OrAlert (ORAL-691) tests for:

  • Amphetamine (AMP) 50 ng/mL
  • Methamphetamine (mAMP) 50 ng/mL
  • Cocaine (COC) 20 ng/mL
  • Opiates (OPI) 40 ng/mL
  • Marijuana (THC) parent THC at 100 ng/mL and THC-COOH at 12 ng/mL
  • Phencyclidine (PCP) 10 ng/mL

Methadone (MTD) has its own test that must be used to detect it. Typically that is a urine test.

Hydrocodone
Date: 3/19/2012
Got a script for hydrocodone and will be getting a gc/ms drug test in a few days. How far back will the test pick up hydrocodone in my system? Can it pin point the amount I injested on a certain day? I just want to know more about the test the military is going to use. I don’t know if it’s a common thing to worry about, but I have a legitimate script handy and take 1 everyday even though the bottle says “Take one every 4-6 hours needed”

Mike

AskDocWeb: Hydrocodone has a short half-life (3.8 hours) and is usually out of your system within 20 hours. However, the metabolites or byproducts of its use may persist in the body much longer. Depending on the amount and frequency of use, etc., it may be detected anywhere from five days up to a month after discontinuing the drug.

The typical dipstick test just gives a yes or no answer to the presence of drugs of abuse but doesn’t give a specific amount. The GC/MS test is much more accurate and will be able to show the exact amount in your sample. If you have a prescription for hydrocodone then you have a legitimate reason for it to show up on the test.

Positive for cocaine
Date: 3/19/2012
My mother has taken a drug hair test and it came back postive for cocain but she dont not do any drugs and her levels was very low can you tell me what could have caused this problem?

Eunika

AskDocWeb: Here is the current list of possibilities:

  • Some antibiotics such as Amoxicillin and Ampicillin
  • tonic water
  • products made from cola leaf (tea, flour, and oil)
  • buprivacaine (brand names: Marcain, Marcaine, Sensorcaine and Vivacaine)
  • diabetes
  • kidney disease

Why kidney disease or diabetes causes some urine tests to return false positives is unknown.

False positive for benzos
Date: 3/19/2012
To whom it may concern,

I tested positive for benzos today during a job interview drug screen; I am not a drug user! The only thing I take are two thyroid medications (Armor and generic Synthroid). I do however take natural remedies for stress and sleep which include l-Tryptophan and melatonin at night and occasionally kava kava and passion flower. I need documentation that these supplements can mimic benzos on a urine screen. I offered to take a blood test to prove my innocence under the advice of my pharmacist but the employer declined.

Help!

Thank you!

Beth

AskDocWeb: Sorry Beth, none of the supplements that you list are known to mimic benzos on urine tests nor are there any thyroid medications on the list of possible causes for a false positive. If your pharmacist has other information maybe they can help.

Jamie

AskDocWeb: Klonopin may test positive for Benzodiazepines and suboxone may test false positive for oxycodone. Please see the link for “What to do if CPS workers are investigating you” on page 169. There is some good advice there.

False positive for cocaine
Date: 3/20/2012
Have recently tested Pos for Cocaine. Also have taken Amoxicilin just prior to testing.
I dont use cocaine. I search for possible false positive test results and found that the drug Amoxicilin could cause this as can cough drops containing benzocaine.
I spoke with my Pharmacist & he says no to the Amoxixilin but maybe on the cough drops.
Can you provide more detailed information on this for me? Thank you,

Chris

AskDocWeb: We have sources references that say that cough suppressants have shown up on urine tests as false positives for heroin, opiates, and morphine but none of them say it might show up as cocaine.

On the other hand, several sources say that using Amoxicillin might cause a false positive for cocaine on urine tests (See references 13, 16, 18, 20, 21, 26, and 29).
