What is oxidant activity?
What is oxidant activity?
Oxidizing Agents: Drug Adulteration Tests What oxidant activity means on a drug test is that specific tampering has occurred to alter the test’s results, as normal urine does not contain these oxidants.
What substances have antioxidant activity?
Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin.
What do you need to know about oxidant activity?
A positive result for oxidant activity should be considered when interpreting drug results. Oxidants can cause decreased levels or negative results for certain drugs, either by masking the drug’s presence or by actually destroying the drug in the sample. The temperature of a sample is also an important characteristic to note.
What is the definition of an oxidant in chemistry?
Oxidant Definition in Chemistry. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. An oxidant is a reactant that oxidizes or removes electrons from other reactants during a redox reaction.
How is an oxidant related to a redox reaction?
Updated November 04, 2019 An oxidant is a reactant that oxidizes or removes electrons from other reactants during a redox reaction. An oxidant may also be called an oxidizer or oxidizing agent. When the oxidant includes oxygen, it may be called an oxygenation reagent or oxygen-atom transfer (OT) agent.
What kind of chemicals are used in drug tests?
Oxidants and PCC, OX/PCC Oxidizing agents such as bleach and hydrogen peroxide in the employee drug test urine are generally indications of adulteration. Pyridinium chlorochromate (sold under the brand name UrineLuck) is a commonly used adulterant.

What’s the expiration date for oxidants in urine?

How to test for oxidants adulteration in urine?
One of the best ways to test for adulteration or dilution is to determine certain urinary characteristics such as pH, specific gravity and creatinine and to detect the presence of oxidants/PCC, nitrites or glutaraldehyde in urine.
