What does immunoassay interference mean?
Immunoassay interference refers to factors that can impact the accuracy of immunoassay test results by causing false positive or false negative outcomes.

Does Levaquin make a drug screen test-positive?
Levaquin is an antibiotic. Just tell the lab tech that you have recently taken it and they should be able to rule it out of the screening. If you do not inform them, it could potentially show as a false positive for opiates. This is from Levaquins web site: "Some quinolones, including levofloxacin, may produce false-positive urine screening results for opiates using commercially available immunoassay kits. Confirmation of positive opiate screens by more specific methods may be necessary."

Can diabetes cause false positive alcohol test results?
Diabetes can potentially cause false positive alcohol test results due to the presence of high levels of acetone in the breath of individuals with uncontrolled diabetes. Acetone is a ketone body produced during the breakdown of fatty acids for energy in the absence of sufficient insulin. Some breathalyzer devices may not be able to distinguish between acetone and ethanol, leading to a false positive result for alcohol consumption in individuals with diabetes. It is important for individuals with diabetes to inform testing personnel about their condition to prevent misinterpretation of test results.
