Technology has gotten better over the years, and false positive drug tests aren&#8217;t as common as they used to be, but they can still happen. The good thing is that you&#8217;re not alone! Getting your drug test from professionals like those at ARCpoint Labs of Omaha is the best way to ensure you have expert guidance throughout the process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-a-false-positive-drug-test\"><strong>What Is a False Positive Drug Test?<\/strong><\/h2>\n\n\n\n<p>A false positive is any kind of test that indicates that someone&#8217;s taken a substance when they actually haven&#8217;t. These can happen for a lot of reasons, but most commonly, false positives are caused when a person has eaten or taken a substance that&#8217;s closely related to the drug being tested for. If you have a false positive on a drug test, don&#8217;t panic! Follow-up testing can help clear up your situation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-common-medications-that-may-affect-test-results\"><strong>Common Medications that May Affect Test Results<\/strong><\/h2>\n\n\n\n<p>There are many classes of medications, and a lot of those are chemically similar to the drugs that employers and individuals commonly test for. A lot of drug tests don&#8217;t look for the drug itself, but the chemicals that stay in your body afterward. Unfortunately, these chemicals aren&#8217;t unique, and sometimes more than one medication can produce them. This is called &#8220;cross-reactivity,&#8221; and it&#8217;s why it&#8217;s so important to bring a list of all your current medications (including vitamins and over-the-counter medicine like ibuprofen) to your drug test.&nbsp;<\/p>\n\n\n\n<p>Not all medications will cause false positives on all tests, but some of the most common medication classes that can cause issues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>ADHD medications<\/li>\n\n\n\n<li>Decongestants (especially ephedrine and pseudoephedrine)<\/li>\n\n\n\n<li>Phentermine and other stimulant diet pills<\/li>\n\n\n\n<li>Antidepressants<\/li>\n\n\n\n<li>Painkillers<\/li>\n\n\n\n<li>Anti-inflammatory drugs like ibuprofen<\/li>\n\n\n\n<li>Antibiotics\u00a0<\/li>\n\n\n\n<li>Vitamin supplements derived from hemp oil<\/li>\n\n\n\n<li>Proton pump inhibitors (for acid reflux)<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-foods-and-everyday-products-that-can-raise-questions\"><strong>Foods and Everyday Products that Can Raise Questions<\/strong><\/h2>\n\n\n\n<p>A lot of drugs come from natural products, and this means that exposure to these natural products can also cause cross-reactivity and false positives. Some of the most common foods and other products that can cause issues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Poppy seeds\u00a0<\/li>\n\n\n\n<li>Cannabidiol\/CBD products<\/li>\n\n\n\n<li>Coca tea<\/li>\n\n\n\n<li>Hemp seeds<\/li>\n\n\n\n<li>Tonic water<\/li>\n\n\n\n<li>Herbal supplements<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-a-simple-checklist-before-your-drug-test\"><strong>A Simple Checklist Before Your Drug Test<\/strong><\/h2>\n\n\n\n<p>The easiest way to pass your drug test without worrying about false positives is to prepare in advance. If you know you have a drug test coming up, here are some things you can do to reduce your chances of a false positive result.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Make a list of all your medications (prescription and over-the-counter) and supplements to share with the Medical Review Officer, should they call you.<\/li>\n\n\n\n<li>Don&#8217;t stop taking prescribed medications.<\/li>\n\n\n\n<li>Be sure to have your driver&#8217;s license or other ID, along with any other forms or documents your employer or testing provider requires.<\/li>\n\n\n\n<li>Avoid eating or drinking any of the foods or medications that are known for causing false positive test results, unless they&#8217;ve been prescribed to you.<\/li>\n\n\n\n<li>Don&#8217;t take &#8220;cleansers&#8221; or other products that claim to help you get a negative result.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-professional-testing-and-review-matter\"><strong>Why Professional Testing and Review Matter<\/strong><\/h2>\n\n\n\n<p>Having a medical expert on your side can make a huge difference in your drug test. A review by a Medical Review Officer (MRO) like the ones here at ARCpoint Labs gives you the context you need to take your next steps after the results are in. Most importantly, our reviewers can clarify things for employers and employees, finding medical explanations that can be hard to spot just looking at the numbers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-get-clear-answers-with-arcpoint-labs-of-omaha\"><strong>Get Clear Answers with ARCpoint Labs of Omaha<\/strong><\/h2>\n\n\n\n<p>A positive drug test doesn&#8217;t always tell the full story, which is why an MRO review is so important.
