Question

A 25-year-old woman comes to your clinic for a second opinion. She tested positive for amphetamines in a random urine drug test done by her company. During the entire course of her interview, you don't note any signs of a possible amphetamine use disorder. Which among the following substances can cause false positives in amphetamine immunoassays?

A. Alcohol
B. Citalopram
C. Ofloxacin
D. Alprazolam
E. Caffeine

Answer 1

Cocaine, caffeine, and nicotine can cause false positives in amphetamine immunoassays.

Step-by-step explanation:

The substances that can cause false positives in amphetamine immunoassays include:

1. Cocaine: A tropane alkaloid and stimulant drug that is commonly used as a recreational drug.
2. Caffeine: Found in many common medicines, beverages, foods, and even cosmetics.
3. Nicotine: Found in tobacco products and has stimulating effects on the central nervous system.

These substances can potentially interfere with the amphetamine immunoassays and lead to false positive results. It is important to consider these factors when interpreting the results of a drug test.
