In drug test cups, these additives either break down drug metabolites or interfere with the test strips, thereby producing a false negative.<\/span><\/p>\n<h3><b>What Is Adulteration in a Drug Test?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Adulteration refers to the deliberate tampering of a urine sample to alter test outcomes. This can involve adding foreign substances or chemically modifying the sample to prevent detection of drug metabolites. In most cases, adulteration is done to avoid a positive result.<\/span><\/p>\n<h3><b>What Is an Adulterated Drug Test?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">An adulterated drug test is one in which the result confirms that tampering took place. If the validity strip comes back positive for foreign substances such as nitrites or glutaraldehyde, or indicates that the sample&#8217;s natural properties have been altered, the test is generally treated as invalid or as a refusal to test.<\/span><\/p>\n<h3><b>What Is a Urine Adulterant Test and Specimen Validity Test?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A urine adulterant check, often called a Specimen Validity Test (SVT), assesses whether a urine sample is genuine, unaltered human urine rather than directly checking for drugs. SVT checks assess creatinine, pH, specific gravity, oxidants, and nitrites to confirm the sample is valid.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For employers and testing professionals seeking a reliable SVT solution, DrugTests<\/span><b>InBulk<\/b><span style=\"font-weight: 400;\"> offers an <\/span><a href=\"https:\/\/drugtestsinbulk.com\/drug-tests\/adulterant-strips.html\"><span style=\"font-weight: 400;\">adulteration strip<\/span><\/a><span style=\"font-weight: 400;\">, a convenient option for detecting common forms of urine sample tampering.<\/span><\/p>\n<p><a style=\"color: #4d9cbe;\" href=\"https:\/\/drugtestsinbulk.com\/urine-adulteration-strips.html\"><strong>PreScreen Adulteration Strip<\/strong><\/a><\/p>\n<p><a href=\"https:\/\/drugtestsinbulk.com\/urine-adulteration-strips.html\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/drugtestsinbulk.com\/media\/iopt\/catalog\/product\/cache\/9d08971813a040f8f96067a40f75c615\/a\/d\/adulteration-test.webp\" alt=\"PreScreen Adulteration Strip\" width=\"145\" height=\"193\" \/><\/a><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fast dip-and-read urine adulteration testing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Detects 6 key SVT parameters<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">25 strips per jar<\/span><\/li>\n<\/ul>\n<p><a class=\"product-btn\" href=\"https:\/\/drugtestsinbulk.com\/urine-adulteration-strips.html\"><span style=\"font-weight: 400;\">View Product<\/span><\/a><\/p>\n<h2 id=\"section2\"><b>Benefit #1: Detects Sample Tampering Early<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Identifying manipulation at the point of collection reduces the chance of inaccurate results entering the workplace testing process.<\/span><\/p>\n<h3><b>How Drug Test Adulterants Are Detected<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Drug test adulterants are identified through built-in Specimen Validity Tests that use rapid colorimetric chemical reactions.
