What is Immunoassay? Definition and Explanation in the Medical Field
By:Admin
Medical testing has seen vast improvements over the years and currently, one of the most effective ways to diagnose various diseases is through immunoassay. Immunoassay is a procedure that determines the presence and quantity of molecules in a solution such as antibodies, hormones, and other proteins by using an antibody or immunoglobulin binding method. This process has become widely popular and has evolved to become quantitative immunoassay.
Quantitative immunoassay is a testing method that measures the amount of a certain substance in a given sample. This testing process has become a critical tool for the diagnosis of many diseases, such as thyroid abnormalities, cancers, and various infectious diseases. It is also used to monitor therapeutic treatments and to determine the efficiency of vaccines in clinical trials.
The procedure is simple; it involves the mixing of a known volume of sample with reagents in a testing kit. The reagents in the kit are designed to bind to the specific molecules that are being tested for in the sample. The bond between the reagents and the molecule being tested for results in a measurable signal; this signal is then quantified to give the concentration of the molecule in the sample.
There are different types of quantitative immunoassays for measurements. The first of them is the Enzyme-Linked Immunosorbent Assay (ELISA) which uses enzymes to catalyze the reaction and yield a measurable signal. Radioimmunoassay (RIA) is another type of quantitative immunoassay that can detect substances of low concentrations due to the presence of radioactive isotopes within the testing environment.
With the advancements in technology and the availability of more specific antibodies, the sensitivity and accuracy of these tests have improved. More so with the development of fully automated immunoassay analyzers that can handle a high volume of samples with faster turnaround times. These advances have made quantitative immunoassays more accessible and practical, with the test being non-invasive, less expensive, and can be performed outside of the laboratory settings.
In conclusion, quantitative immunoassay has proven to be an effective, efficient, and reliable means of diagnosing diseases. The availability of automated testing systems means it can be conducted efficiently, and the non-invasive nature of the test makes it more acceptable to patients. As technology continues to evolve, it is likely that more specific molecules will be identified for immunoassay procedures, thereby expanding the scope of this critical diagnostic tool.

What is ELISA Test and How Does it Work in Protein Detection?
ELISA test, or Enzyme-Linked Immunosorbent Assay test, is a sensitive technique used to detect and quantify a wide range of analytes, including proteins, antibodies, hormones, and drugs. It has become one of the most commonly used laboratory tests for diagnosing and monitoring a variety of diseases, such as HIV, hepatitis, cancer, autoimmune disorders, and allergies.The principle behind ELISA test is based on the specific binding of an antigen (or antibody) to its complementary antibody (or antigen) immobilized on a solid support, usually a microplate. The sample containing the analyte of interest is added to the plate and allowed to interact with the antigen-antibody complex. Then, a second antibody conjugated with an enzyme, such as horseradish peroxidase (HRP), is added to the plate. This secondary antibody binds to the analyte-antibody complex and forms a sandwich-like structure. After washing away the unbound components, a substrate for the enzyme, such as a colorimetric or chemiluminescent compound, is added to the plate. The enzyme converts the substrate into a detectable signal, which can be measured by a spectrophotometer or a luminometer.The advantage of ELISA test is its high sensitivity and specificity, which means it can detect very low levels of analytes and distinguish between closely related molecules. ELISA test is also relatively easy to perform, requires minimal equipment, and can be adapted to high-throughput screening. However, ELISA test has some limitations, such as its dependence on the quality and specificity of the antibodies used, the possibility of interference from matrix components in the sample, and the potential for false positive or negative results.Immunoassay is a general term that encompasses a variety of methods for detecting and quantifying molecules based on the specific interaction between antigens and antibodies. ELISA test is just one type of immunoassay, which uses enzymes as markers. Other types of immunoassay include radioimmunoassay (RIA), fluorescence immunoassay (FIA), and chemiluminescence immunoassay (CLIA).In conclusion, ELISA test is an important tool in the field of diagnostics and research, and has contributed to the understanding and treatment of numerous diseases. Immunoassay is a versatile technique with many applications, and continues to evolve with advances in technology and knowledge. As such, it is essential to stay informed and up-to-date on the latest developments in immunoassay and ELISA test.
Singapore authorities studying use of ART for screening incoming travelers
The Ministry of Health (MOH) in Singapore is taking steps to improve the screening process for incoming travellers by trialling the use of antigen rapid test (ART) self-test kits at Changi Airport.The study is part of a wider effort to replace polymerase chain reaction (PCR) testing with faster and more efficient methods of COVID-19 detection. While PCR tests are considered the gold standard for COVID-19 diagnosis, they can take several hours to produce results, which can delay the travel process and increase the risk of transmission at airports.ARTs are a new type of rapid test that can detect the presence of COVID-19 antigens in just 15-30 minutes. They work by using a nasal or throat swab to collect a sample of mucus, which is then loaded onto a test strip. If the test detects the presence of viral antigens, it will produce a visible result within minutes.The MOH is currently testing the effectiveness of ARTs on on-arrival passengers at Changi Airport, with the goal of establishing a faster and more streamlined screening process. The results of the study will help to determine whether ARTs can be used as a replacement for PCR tests, particularly for travellers who are not showing symptoms of COVID-19.There are a number of advantages to using ARTs for COVID-19 screening. Firstly, they produce results much faster than PCR tests, which can take several hours to process. This could significantly reduce the amount of time that travellers have to spend at airports waiting for their test results, which in turn could reduce the risk of transmission.Secondly, ARTs are much cheaper than PCR tests and require less specialised equipment, which could make them more practical for use in high-volume screening scenarios such as airports. This could help to reduce the cost of COVID-19 screening, which is currently a major financial burden on both travellers and governments.However, there are also some limitations to using ARTs for COVID-19 screening. For example, they are generally less sensitive than PCR tests, which means that they may produce false negative results in some cases. Additionally, they may be less effective at detecting certain variants of the virus, particularly those that are less common.Despite these limitations, the MOH is hopeful that ARTs could play a significant role in the fight against COVID-19, particularly in the context of travel screening. By providing faster and more cost-effective testing options, ARTs could help to establish a more efficient and effective screening process, which in turn could help to reduce the spread of COVID-19 both locally and globally.In conclusion, the development of ARTs for COVID-19 screening represents an important step forward in terms of public health and safety. By providing a faster and more streamlined screening process, ARTs could help to reduce the risk of transmission at airports and other high-volume areas. While more research is needed to determine the effectiveness of ARTs in different contexts, the MOH's study is an important first step towards establishing a more effective and efficient screening process for travellers.
