Alcohol Detection, Results &amp; When It\u2019s Used"},"content":{"rendered":"\n<ul class=\"wp-block-list\">\n<li>A PEth test identifies a direct alcohol biomarker in a blood sample.<\/li>\n\n\n\n<li>It covers a longer testing window than urine or breath tests can.<\/li>\n\n\n\n<li>Results reflect laboratory findings and should not be viewed as a medical diagnosis.<\/li>\n<\/ul>\n\n\n\n<p>If you need to complete alcohol testing, you may have heard the term PEth test. This method of detecting alcohol is becoming more common for legal cases, monitoring programs, and professional recruitments. Because it looks back further than standard methods, it&#8217;s becoming a common choice when a more complete picture of alcohol exposure is desired. Let&#8217;s look at what the test measures, how ARCpoint Labs of Omaha handles collection, and what you can expect from the results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-does-a-peth-test-measure\"><strong>What Does a PEth Test Measure?<\/strong><\/h2>\n\n\n\n<p>PEth is short for phosphatidylethanol, which is a compound that only forms in red blood cell membranes when alcohol is present. This compound is produced directly from ethanol exposure and stays in the body longer than alcohol itself, making it ideal for getting insights into drinking patterns over time, rather than just confirming the presence of alcohol at the time blood is drawn.<\/p>\n\n\n\n<p>Now that you know what the test is, it&#8217;s important to understand what it isn&#8217;t. A PEth test cannot diagnose alcohol use disorder or any other medical condition. It merely returns laboratory information indicating alcohol consumption.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-peth-alcohol-testing-work\"><strong>How Does PEth Alcohol Testing Work?<\/strong><\/h2>\n\n\n\n<p>When a PEth test is requested at ARCpoint Labs of Omaha, a trained staff member will draw a blood sample in a professional, discreet setting. Once the blood is drawn, we send it to a laboratory, which performs the analysis and reports the result.<\/p>\n\n\n\n<p>Because PEth works with blood markers that persist longer than alcohol, it sticks around in the blood for roughly two to four weeks. This is a significant improvement over the few days of coverage provided by urine testing and an even shorter period for breath testing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-long-can-a-peth-test-detect-alcohol\"><strong>How Long Can a PEth Test Detect Alcohol?<\/strong><\/h2>\n\n\n\n<p>Although two to four weeks is the standard answer, this range isn&#8217;t fixed. The actual detection period depends on how much someone drinks, their individual biology, and the lab method used. The test also only detects that alcohol was consumed; it cannot provide any indication about when it was consumed or the exact amount that was consumed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-do-peth-test-results-mean\"><strong>What Do PEth Test Results Mean?<\/strong><\/h2>\n\n\n\n<p>PEth test results show a measured concentration of PEth in the blood, rather than a simple yes-or-no answer. Results below a certain level are considered negative, meaning the person most likely did not consume alcohol. Higher concentrations correspond with more frequent alcohol consumption but do not indicate exact amounts.<\/p>\n\n\n\n<p>Because the result is a range, a single result rarely tells the whole story. Often, different programs will have different thresholds. Legal, workplace, treatment facilities, and medical concerns all have different stakes, so some are naturally stricter than others.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-is-a-peth-blood-test-used\"><strong>When Is a PEth Blood Test Used?<\/strong><\/h2>\n\n\n\n<p>PEth testing is common in a number of situations, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Court, probation, or custody-related documentation<\/li>\n\n\n\n<li>Treatment, recovery, or abstinence monitoring<\/li>\n\n\n\n<li>Medical or transplant program requirements<\/li>\n\n\n\n<li>Professional licensing or workplace policies, where applicable<\/li>\n\n\n\n<li>Personal accountability or documentation<\/li>\n<\/ul>\n\n\n\n<p>Because requirements vary from one purpose to the next, confirm the specifics with whoever is requesting the test. Asking about the detection window they&#8217;ll be looking for, the format, and the deadlines will help you understand the test and its ramifications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-schedule-a-peth-test-in-omaha\"><strong>Schedule a PEth Test in Omaha<\/strong><\/h2>\n\n\n\n<p>At ARCpoint Labs of Omaha, you can expect a confidential, professional specimen collection process for every test you request, including <a href=\"https:\/\/www.arcpointlabs.com\/omaha\/tests\/peth-test\/\">PEth testing<\/a>.

Workers in transportation (truck drivers, bus drivers, train conductors, pilots, etc.) and pipeline industries are required by federal law to pass a standard 5-panel drug test using a urine sample.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Companies that are not required to meet DOT drug testing standards can perform similar, more extensive, or less extensive drug testing. For instance, DOT screening covers cannabis and alcohol, while non-DOT companies may choose not to test for those substances.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>They also can choose to conduct testing through urine, saliva, or hair samples, which offer other benefits. Hair samples are more effective at unearthing long-term drug usage and are less likely to be fooled by someone abstaining from drugs for a short period before a test. Saliva samples offer similar findings to urine, but they are less susceptible to employees substituting a fake sample since saliva is collected by the tester.&nbsp;&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Companies that adopt drug testing must establish a policy that treats all employees equally and meets any state regulations.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"h-when-do-employers-use-non-dot-drug-testing\"><strong>When Do Employers Use Non-DOT Drug Testing?<\/strong><\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>Most people might think of company drug testing as a pre-screening option for potential hires, but an effective drug-testing policy must also address ongoing testing to maintain a safe workplace.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Non-DOT drug testing includes features such as annual or random testing, post-accident and follow-up testing, and testing under reasonable suspicion.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>If a company requires an annual physical, drug testing is often a component. Random testing may be set up such that a company tests a certain percentage of the workforce each year through a blind draw. Post-accident testing is a common procedure to determine if impairment was a contributing factor. Follow-up testing may come after an accident as a condition to return to work or in the wake of a positive test as a condition of continued employment.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"h-how-is-a-non-dot-drug-test-performed\"><strong>How Is a Non-DOT Drug Test Performed?<\/strong><\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>DOT drug testing requires a 5-panel urine test conducted by a SAMHSA-certified lab. Companies establish their policies about how non-DOT drug testing is completed. Though testing can be conducted by a SAMHSA-certified lab, other labs also can be used.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Companies also choose whether to limit themselves to urine testing or keep their options open to use saliva or hair testing, based on circumstances. For example, if a company routinely conducts annual tests around an employee's work anniversary, employees might try to fool the test by abstaining for a few days prior to the test. In such cases, a hair sample provides a more comprehensive analysis of an employee's potential drug use.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Employees are often sent to the test provider to provide samples, but some companies offer mobile services to conduct programs such as random or annual tests.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>ARCpoint Labs of Omaha provides trained staff to help companies set up drug testing policies and conduct tests in our facilities, on-site, or through our mobile services.&nbsp;<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"h-what-is-a-non-dot-breath-alcohol-test\"><strong>What Is a Non-DOT Breath Alcohol Test?<\/strong><\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>Non-DOT breath alcohol tests determine current impairment and are offered primarily as post-accident or reasonable suspicion options.
