In Swedish, the term &#8216;analyscertifikat&#8217; or &#8216;CBD-analyscertifikat&#8217; is often used when the sample concerns a CBD raw material or product.\n<\/p>\n<p>\nThe laboratory uses the document to report the results from an identified sample. <strong>For example<\/strong>, the certificate can show which cannabinoids the laboratory has measured and in what quantities.\n<\/p>\n<p>\n<strong>Furthermore<\/strong>, the document may contain information regarding the analysis date, method, sample number, and reporting limits.\n<\/p>\n<p>\nA COA, however, only shows the parameters that the laboratory has actually investigated. <strong>Therefore<\/strong>, you should not interpret a cannabinoid analysis as proof that the product has also been tested for, for example, heavy metals, microorganisms, or pesticide residues.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>In short:<\/strong> a COA describes the laboratory results for the sample identified by the document \u2013 not automatically all properties of the product.\n<\/p>\n<\/div>\n<\/section>\n<section id=\"providentitet\">\n<h2>Verify the Sample in Your CBD Certificate of Analysis<\/h2>\n<p>\n<strong>Start by<\/strong> verifying the identity of the sample. Look for the sample name, product name, laboratory sample number, and any batch code.\n<\/p>\n<p>\nTogether, these details show which material the laboratory actually received and analyzed.\n<\/p>\n<p>\n<strong>Next<\/strong>, you should compare the certificate&#8217;s details with the label and the product page. If the certificate specifies &#8220;CBD isolate,&#8221; for example, but the product page describes a finished oil blend, the analysis likely applies to the raw material and not the oil in the bottle.\n<\/p>\n<p>\nAlso check who submitted the sample. A laboratory analyzes the material provided, but the analysis does not automatically confirm the entire production chain or that subsequent production batches have the same composition.\n<\/p>\n<\/section>\n<section id=\"batchnummer\">\n<h2>What Do Batch Numbers and Sample Numbers Show?<\/h2>\n<p>\nA batch number identifies a specific production run. <strong>In this way<\/strong>, the manufacturer can link raw material, production, and documentation to the same series of products.\n<\/p>\n<p>\nThe laboratory may also create its own sample number. This number identifies the analysis assignment in the laboratory&#8217;s system but does not necessarily replace the manufacturer&#8217;s batch number.\n<\/p>\n<p>\n<strong>For best traceability<\/strong>, the certificate and the product label should share a clear identifier. If the link is missing, it becomes harder to determine if the analysis applies to the goods actually in stock.\n<\/p>\n<h3>Is an Old COA Still Relevant?<\/h3>\n<p>\nAn older certificate may describe a previous raw material delivery or production run. <strong>However<\/strong>, the document does not automatically verify a new batch.\n<\/p>\n<p>\nTherefore, the seller should clearly state which certificate belongs to the current raw material or product.\n<\/p>\n<\/section>\n<section id=\"cannabinoidprofil\">\n<h2>How to Read the Cannabinoid Profile in a CBD Certificate of Analysis<\/h2>\n<p>\nThe cannabinoid profile lists the substances the laboratory has searched for. Common analytes can include, for example, CBD, CBDA, CBDV, CBG, CBGA, CBN, delta-9-THC, delta-8-THC, and THCA.\n<\/p>\n<p>\n<strong>First<\/strong>, you should read each line separately. The result may be shown as a numerical value, &#8220;not detected,&#8221; &#8220;under LOD,&#8221; or &#8220;under LOQ.&#8221;\n<\/p>\n<p>\n<strong>Subsequently<\/strong>, you need to read the laboratory&#8217;s explanations and method notes to understand exactly what the designations mean.\n<\/p>\n<p>\nFor a CBD isolate, a very high CBD content and low levels of other cannabinoids are normally expected. A spectrum extract, on the other hand, should show a broader profile if the product name suggests that several cannabinoids remain.\n<\/p>\n<p>\nA 2024 study analyzed 202 commercial CBD products and reported discrepancies between product category, declared content, and measured composition. <strong>Therefore<\/strong>, the laboratory result is more important than the product name alone.\n<\/p>\n<p>\nRead the scientific study on<br \/>\n<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38562466\/\" target=\"_blank\" rel=\"noopener noreferrer\"><br \/>\nlabeling and laboratory content in commercial CBD products<br \/>\n<\/a>.\n<\/p>\n<\/section>\n<section id=\"enheter\">\n<h2>Understanding Percentage by Weight, mg\/g, and mg\/ml<\/h2>\n<p>\nLaboratories can report cannabinoids in several different units. <strong>Therefore<\/strong>, you must read both the figure and the unit before comparing two results.\n<\/p>\n<h3>Percentage by Weight<\/h3>\n<p>\nPercentage by weight, often written as % w\/w, describes how much of the sample&#8217;s weight consists of the substance.\n<\/p>\n<p>\nA result of 99% CBD in an isolate does not, therefore, mean that a finished oil automatically contains 99% CBD.\n<\/p>\n<h3>Milligrams per Gram<\/h3>\n<p>\nMg\/g indicates the amount of substance per gram of sample. Laboratories often use this unit for solid raw materials, extracts, and concentrates.\n<\/p>\n<h3>Milligrams per Milliliter<\/h3>\n<p>\nMg\/ml describes the amount of substance per milliliter of liquid and can therefore be relevant for finished oil blends.\n<\/p>\n<p>\n<strong>However<\/strong>, it is not always possible to convert directly between percentage by weight and mg\/ml without information about the density of the mixture.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>Important:<\/strong> do not compare a raw material analysis in percentage by weight with a product declaration in milligrams per bottle as if the figures describe the same thing.\n<\/p>\n<\/div>\n<\/section>\n<section id=\"lod-loq\">\n<h2>What Do LOD and LOQ Mean in a CBD Certificate of Analysis?<\/h2>\n<p>\nLOD means <em>limit of detection<\/em>. It describes the lowest level at which the laboratory can distinguish the substance&#8217;s signal from background noise.\n<\/p>\n<p>\nLOQ means <em>limit of quantification<\/em>. It describes the lowest level at which the laboratory can state a quantity with sufficient precision and accuracy.\n<\/p>\n<p>\n<strong>When a result is below LOD<\/strong>, the laboratory cannot detect the substance with the current method above this limit.\n<\/p>\n<p>\n<strong>If the result is below LOQ<\/strong>, a signal may, however, be below the level where the laboratory can state a sufficiently certain quantity.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>Below LOQ does not, therefore, automatically mean absolute zero.<\/strong> The result must always be interpreted together with the laboratory&#8217;s reporting limit.\n<\/p>\n<\/div>\n<p>\nEurachem&#8217;s guidance for method validation describes how laboratories assess, among other things, detection and quantification limits.\n<\/p>\n<p>\nRead <a href=\"https:\/\/www.eurachem.org\/images\/stories\/Guides\/pdf\/MV_guide_3rd_ed_V1_EN.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">Eurachem&#8217;s guide to analytical method validation<\/a>.\n<\/p>\n<\/section>\n<section id=\"thc\">\n<h2>How to Interpret the THC Result<\/h2>\n<p>\n<strong>First, check<\/strong> which form of THC the laboratory has analyzed. A certificate may, for example, report delta-9-THC, delta-8-THC, THCA, and total THC on separate lines.\n<\/p>\n<p>\n<strong>Next<\/strong>, you need to compare the result with the reporting limit. The phrases &#8220;below LOQ&#8221; and &#8220;not detected&#8221; do not automatically mean the same thing as a guaranteed absolute zero content.\n<\/p>\n<p>\nIt is therefore better to reproduce the laboratory&#8217;s results exactly.\n<\/p>\n<div class=\"information-box\">\n<p>\n<strong>Example of exact wording:<\/strong><br \/>&#8220;Delta-9-THC was reported below the laboratory&#8217;s quantification limit of 0.05 percentage by weight in the analyzed raw material sample.&#8221;\n<\/p>\n<\/div>\n<p>\n<strong>At the same time<\/strong>, a raw material result should not be automatically transferred to a finished product without separate analysis or relevant documentation.\n<\/p>\n<p>\nFor current Swedish authority information, you can read<br \/>\n<a href=\"https:\/\/www.lakemedelsverket.se\/sv\/behandling-och-forskrivning\/kopa-anvanda-och-hantera\/vad-ar-ett-lakemedel\/cannabidiol-cbd\" target=\"_blank\" rel=\"noopener noreferrer\"><br \/>\nThe Medical Products Agency&#8217;s information on cannabidiol<br \/>\n<\/a>.\n<\/p>\n<\/section>\n<section id=\"metod\">\n<h2>Check Which Analysis Method the Laboratory Used<\/h2>\n<p>\nThe analysis method affects which substances the laboratory can separate and measure. For cannabinoids, laboratories often use liquid chromatographic methods, such as HPLC or UPLC.\n<\/p>\n<p>\nAOAC International has, for example, approved an LC-DAD method for the analysis of cannabinoids in cannabis plant material, concentrates, and oils.\n<\/p>\n<p>\nA validated method should demonstrate sufficient selectivity, precision, and accuracy for its intended use.\n<\/p>\n<p>\n<strong>At the same time<\/strong>, laboratories may use different sample preparation, instruments, reference standards, and reporting limits.
