Agglutination Test Kits

Agglutination Test Kits & Serology Reagents

Agglutination, or clumping, occurs when an antigen comes into contact with its corresponding antibody. We offer three different agglutination test kits that range:

  • Febrile antigens
    Our kits are used, for example, to identify brucella, proteus, salmonella and rickettsia infections.
  • Latex serology kits
    The range includes kits used to identify streptococcal infections, levels of C-reactive protein that would indicate high levels of inflammation in the body and rheumatoid factors that would indicate a diagnosis of rheumatoid arthritis.
  • Syphilis reagents
    Our kits are used to detect antibodies to syphilis and Treponema pallidum.

Febrile Antigens

We offer a range of febrile antigens that enable brucella, proteus and salmonella bacterial infections to be diagnosed.

Febrile antigens, which are also known as Widal reagents, are bacterial antigen suspensions that are stained for the purpose of giving clear readings in agglutination tests. They are used to measure antibodies in a patient’s serum.

In response to a bacterial infection, the body produces antibodies to the pathogen that has invaded it. When a serum sample from the patient is mixed with the relevant febrile antigen, agglutination occurs if antibodies to that antigen are present, indicating that the patient is infected.

The Widal test remains at the core of rapid screening for enteric fevers in many laboratories around the world. Our assays use stained somatic and flagellar bacterial antigen suspensions to enhance the visibility of the agglutination, and our specifically designed controls help produce accurate results. These reagents and kits offer an efficient, cost-effective solution for the detection and titration of salmonella, brucella, proteus and certain rickettsia bacterial infections.

Latex Serology Kits

Our portfolio includes latex serology kits to detect ASO (anti-streptolysin-O), CRP (C-reactive protein), and RF (rheumatoid factors) in serum samples. These latex assays come in both 100T and 150T kit sizes, complete with positive and negative controls. Alternatively, there’s an option to purchase a 100T reagent-only package.

The full kits include all the required consumables. They use the common agglutination method for efficient, reliable testing to ascertain the causes of inflammation, rheumatoid disorders and streptococcal infections.

Latex agglutination testing, which is sometimes referred to as latex serology, is used to identify a variety of antibodies in samples such as saliva, urine, blood or cerebrospinal fluid.

Latex serology tests are used to ascertain whether specific antigens or antibodies are present in a sample. This is done by applying the sample to antigen- or antibody-coated latex beads. If the suspected substance (antibodies or an antigen) is present in the sample, the latex beads clump together (agglutinate).

The results of latex serology tests can be obtained within 15 minutes to an hour, allowing a rapid diagnosis to be made, which is obviously a significant advantage.

Syphilis Reagents

Our two agglutination kits are designed for syphilis detection: one targets syphilis antibodies in general, while the other is specifically formulated to detect IgG and IgM antibodies related to Treponema pallidum, the causative organism of syphilis.

Regardless of the screening approach taken or testing algorithm used, it is essential to combine treponemal and non-treponemal serology assays for the accurate detection and titration of Treponema pallidum infections. Used both for diagnosis and to evaluate the stage of an infection to aid the choice of antibiotic therapy, Prestige Diagnostics PRP and TPHA kits provide stable reagents in convenient pack sizes.

Agglutination Kit Manufacturing

Prestige Diagnostics is recognised for its quality and has ISO:13485:2016 certification. As a UK IVD manufacturer, all our agglutination kits carry the UKCA mark of the MHRA (Medicines and Healthcare products Regulatory Agency), the relevant executive agency of the UK government.

That means that these products are approved for sale in Great Britain and that we can apply for the certificate of free sale required by most of our distributors around the world.

We are always happy to help.

How does it differ?

 

An agglutination test is a diagnostic procedure used to detect the presence of specific antigens or antibodies in a patient’s sample, usually blood or serum, by observing the clumping of cells or particles.

It’s particularly effective in diagnosing various bacterial infections and immune responses. On the other hand, a saline agglutination test, often used in blood typing and compatibility testing, involves mixing blood cells with a saline solution and observing agglutination reactions.

The main difference lies in the test’s application: standard agglutination tests are commonly used for a broader range of conditions, including infections and autoimmune disorders, while saline agglutination tests are more specific to blood-related diagnoses.

Enhancing the Detection Process

 

The Agglutination Kits from Prestige Diagnostics are specially designed to improve disease detection accuracy and efficiency. These kits, compared to standard Serology Reagents, offer a rapid, reliable, and simplified method for identifying various health conditions, from bacterial infections like syphilis to autoimmune disorders like rheumatoid arthritis. Thanks to their ISO:13485:2016 certification and approval by regulatory bodies, these kits meet high-quality standards, ensuring dependable results for medical professionals and patients alike.
