Is it possible to get a false positive alcohol reading if you did not have any alcohol?

Is it possible to get a false positive alcohol reading if you did not have any alcohol?

Yes: If you are refering to urine tests that look for metabolites, it is possible but not likely. Could be excessive use of alcohol based hand sanitizers. One case I'm aware of is using vanilla extract in alcohol base put in coffee, though using it in cooking should get rid of alcohol. Possible using alcohol based mouthwash, should be avoided any way in someone with history of alcoholism. Nyquil. ...Read more

Hi...can using hair products containing fruit extracts as well as the alochols used in hair products cause a false positive for etg alcohol tests?

Hi...can using hair products containing fruit extracts as well as the alochols used in hair products cause a false positive for etg alcohol tests?

Unless U drink UR: Shampoo, you should not test positive for an alcohol test. That's when you're drinking alcoholic beverages, not using shampoo. So you are safe! Fruit extracts also don't cause a positive alcohol blood test too. Thank goodness! Or we'd have a huge public health crisis on our hands with personal care products. Safe to continue using your fruit extract shampoos. ...Read more

Can elderberry trigger a false positive on a UA? I am in recovery for alcohol and submit to regular drug/alcohol screening

Can elderberry trigger a false positive on a UA? I am in recovery for alcohol and submit to regular drug/alcohol screening

No: However, some "herbal" remedies aren't what they're labeled to be. It's caveat emptor. One of the very common situations in alcohol recovery is a specimen that sits too long before it's checked -- it'll give a false positive for ethyl glucuronide. Might this have happened? ...Read more

Will the sugar alcohol found in sugar free gums, sodas, sugar substitutes produce a false positive on an etg test?

Will the sugar alcohol found in sugar free gums, sodas, sugar substitutes produce a false positive on an etg test?

No: There isn't anything in sugar substitutes that will cause the etg (ethyl glucuronide) test to show positive. However, because etg test measures products of metabolism of ethyl alcohol from any source, it is sensitive to small amounts of alcohol. It will detect ingestion or exposure to alcohol in mouthwash, cough syrup and other medicated syrups, and possibly even hand sanitizers. ...Read more

Will over-the-counter medicine for tooth ache that has benzyl alcohol in it cause false positive on 80 hr test I take?

Toothache: OTC remedies will not cure infected tooth, only mask the symptoms as the infection worsens, spreads, and can farm other tissues. You have a more serious problem than alcohol residue in a blood test. Seek professional care now. ...Read more

Is it possible to get a "false positive" for pseudonormalization on an Echo if everything else is perfectly fine on it?

Careful! What does: "perfectly fine" mean in an industry which calls the central +/- 2 Standard Deviations (central 95.8%) of any human variable "normal" or within "reference range". I strongly suggest getting the video images, study them yourself, work at understanding differences between what you see & what is said about them, etc. Back to first question: complex issues commonly used to explain away inaccuracy. ...Read more

Is it possible to get a false positive herpes culture test? How often does it occur? What is the reasoning for it?

Is it possible to get a false positive herpes culture test? How often does it occur? What is the reasoning for it?

Rarely if ever: False positive results are very unlikely for HSV culture. If the test was actually a DNA test (PCR test), there is a slightly higher chance of false pos, but still very unlikely. If you have had a positive culture or PCR, for sure you have herpes at whatever site was tested (genital, oral). But if a blood antibody test, not culture or PCR, false positive results are quite common. Good luck. ...Read more

Is it possible to get a false positive TSH test result caused by stress if your TSH was 11.13?

Is it possible to get a false positive TSH test result caused by stress if your TSH was 11.13?

Complex: Hi. It's unlikely "stress" can give a false positive TSH elevation, but "stress" comes in multiple flavors. If a person is severely ill (usually ICU-tpye ill or at least hospitalized), an adaptive response (unfortunately) called "euthyroid sick syndrome" can show a TSH elevation in that range during a phase of the condition. Only in a case like that. Stress like a final exam next week? No. ...Read more

Can you explain if it's possible to get a false positive of cancer from a needle aspiration?

Can you explain if it's possible to get a false positive of cancer from a needle aspiration?

Yes: My pathology colleagues can probably answer this better but a needle aspirate often yields a few isolated cells that may look funky because of the trauma they went through during the procedure. Also, they are taken out of the context of their surroundings and you cannot see the architecture of the tissue. Pathologists are awesome but only god is perfect. ...Read more
