Immunoassay Drug Test: How It Works and What It Tests For?

Drug testing is valuable in clinical care and forensic science. Accurate Diagnosis is based on the detection of illegally abused drugs, prescription medicine, or drug metabolites from various biological samples from urine, saliva, blood, and others. Among the many methods used for drug screening, there is one unique method, and that is the immunoassay antigen test, which relies wholly and entirely on the phenomenon of antibody-antigen interaction in the identification of drugs or their metabolites. It is widely preferred, as the immunoassay test returns rapid less expensive results, thereby making it precious in emergency rooms or workplace drug monitoring settings. Diamond Diagnostics also supports accurate tests by employing high-quality immunology analyzers.

Knowing the role of an immunoassay blood test, “what does an immunoassay test for”, and “how do immunoassay drug tests work” is very important for lab professionals and doctors, as well as the greater public, in maintaining health safety and compliance both in the clinical and non-clinical sectors.

What is an Immunoassay Antigen Test?

An immunoassay drug test is a biochemical testing technique that applies the interaction between antigens and antibodies to check for the existence of drugs or their metabolites in biological specimens. Because of its fast and efficient way of scanning the substances present within samples of urine, blood, or saliva, this type of diagnostic test has widely been used in the assessment of drug testing. The primary reason for their wide application is the efficiency of drug tests in providing rapid results at a low cost and the capacity to screen for multiple drugs. Whether blood tests are combined with other types of biological sampling, it has undoubtedly become highly in demand over the available options for its ability to be used easily in practice through medical, forensic, or workplace diagnostics. The discussion about “What does an immunoassay test for” concludes by highlighting their role as specific detection tools for drug detection, which facilitates their essential function across a wide range of applications. Now that we have gone through what is an immunoassay test, we shall now cover what does an immunoassay blood test for?

How do Immunoassay drug tests work

A drug test is performed using steps that are well-established in the procedure. The generic samples taken include urine, saliva, or blood and then tested, one of which is the common antibody test. The core interaction between the antibody and antigen drives the primary action mechanism, based on the idea that antibodies in the test mix with antigens from the sample in medications. This reaction produces a signal that is easily observable, like a colour change, indicating whether it's a positive or negative result. That is basically how immunoassay-based drug tests work for such quick identification. The immunoassays applied include ELISA, RIA, and FPIA. All of them have different sensitivity levels and speeds but can detect various drugs or their metabolites.

Advanced equipment from Diamond Diagnostics further enhances the accuracy and reliability of these tests. Some of the high-quality clinical laboratory analyzers include Beckman Access 2, Beckman Access 2+, Abbott Architect i1000SR, Abbott Architect i2000, and many more.

What does an immunoassay test for and Detect?

An immunoassay blood test is set to screen for many different classes of drugs, both legal and prescription, as well as illegal. It can screen for the opiates morphine and codeine, cocaine, cannabinoids of THC in marijuana, amphetamines and methamphetamines, benzodiazepines, and barbiturates. Other drugs like PCP and MDMA are included in this list as well. The advantage of these immunoassay tests is that they identify not only the parent drugs but also their metabolites or byproducts that the body produces as it breaks up these substances to make the test more efficient overall.

Another factor that determines whether a result is positive or negative is the cutoff level. The "cutoff level" is a threshold set to determine if the detected amount of a drug or its metabolites (byproducts of drug metabolism) is clinically significant. If the concentration of a substance in the sample is above this level, the test result is considered positive, indicating a meaningful presence. If it's below this level, the test is negative, suggesting only trace or negligible amounts, possibly from incidental exposure rather than active use. This threshold helps avoid false positives and ensures that only significant levels trigger a positive result. Professionals who interpret results should understand “how do immunoassay drug tests work” and how cutoff levels are applied. Therefore, accurate results can be obtained through high-quality clinical laboratory analyzers, provided by Diamond Diagnostics.

Immunoassay Diagnostic Test Accuracy and Limitations

Although an immunology test is among the most common drug detection techniques due to its speed, cost, and convenience, it does have its own set of disadvantages. One of these disadvantages is the possibility of false positives or false negatives. This could be the result of cross-reactivity, in which certain drugs or dietary supplements react similarly to the intended drug, producing inaccurate findings. The problem is more frequent with initial screening tests such as these respective tests.

To reduce this risk, confirmatory testing is very important, especially after a positive result. Methods such as gas chromatography-mass spectrometry (GC-MS) are more sensitive and specific. They can almost surely give a definitive confirmation due to the accurate identification of the substances detected.

Though limited in many aspects, the immunoassay blood test and other sample types are still commonly used in preliminary screenings of drugs because of their merit in giving results fairly fast and being less expensive. They can test for several drugs all at one time. However, among its limitations is cross-reactivity, and it cannot accurately represent the amount of drugs a person has in their body.

Diamond Diagnostics provides answers to “What does an immunoassay test for” and “How do immunoassay drug tests work” and eventually provides sophisticated clinical laboratory analyzers that increase the reliability of these tests; thus, professionals can better interpret the findings from an immunoassay test in clinics or forensic settings and ensure the outcomes are as accurate as feasible.

Immunoassay vs. Other Drug Testing Methods

While other testing methods may be used to compare an immunoassay diagnostic test, the main difference is in the speed and purpose. Immunoassay blood tests are generally done for rapid, preliminary screenings of drugs because they process large numbers of samples cheaply and quickly. Confirmatory tests are often used for GC-MS because it is more accurate and specific. Whereas the immunoassay antibody tests often generate false positives due to cross-reactivity, GC-MS is far superior in accurately identifying the exact compounds that exist in a sample. Hence, it is considered the gold standard for confirmatory drug testing.

The other common comparison is with High-Performance Liquid Chromatography (HPLC). In HPLC, the concentration of drugs and their metabolites in a sample can be measured very precisely. However, it is slower and costlier than an immunoassay. It is usually reserved for detailed analysis, whereas an immunoassay is preferred because it can screen multiple substances in less time.

The immunoassay blood test is usually the first test performed in a case of urgent drug testing, especially when immediate results are required. Such settings include emergency departments, roadside screenings, or workplace drug monitoring. In these scenarios, if an initial broad screening is adequate, immunoassays can hasten the time to decision. For these types of scenarios, an immunoassay test becomes a convenient first step. For confirmation or more specific analyses, GC-MS or HPLC may be utilized as confirmatory tests. In the analysis of drugs, the mechanisms of immunoassays offer versatility and convenience for laboratory professionals dealing with apparatuses from Diamond Diagnostics.
