Latex Serology Tests

A comprehensive range of qualitative and semi-quantitative latex agglutination tests.

ASO Latex Test (Non Sample Dilution)

Actively growing strains of Group A hemolytic streptococci, together with most strains of Groups C and G, produce Streptolysin-O, an antigenic toxin. Patients with these streptococcal infections form specific antibodies, detection of which aids the diagnosis of recent infection. Together with serological tests, The Plasmatec ASO Latex provides a complete test profile and aids current and prompt diagnosis. The ASO Latex test works by agglutination of latex particles coated with purified Streptolysin-O by ASO. The test is standardized against the World Health Organisation International Standard to have a sensitivity of 200 IU/ml and produces a result in just 2 minutes. This type of test can also be the only way of diagnosing the sequelae of streptococcal infections such as rheumatic or scarlet fever and glomerulonephritis. The ASO latex test kit is provided with ASO test latex, positive and negative controls, pipette stirrers and an agglutination slide.

CRP Latex Test (Non Sample Dilution)

C-Reactive Protein (CRP) levels have been shown to be consistently elevated in a wide variety of infections, inflammatory conditions and other disease states where there is tissue destruction. CRP is also an early indicator of inflammation, with serum levels rising before specific antibody titres or erythrocyte sedimentation rate (ESR) and subsidizing faster than does the ESR. The Plasmatec CRP Latex Test is a rapid latex slide test for the detection of CRP in human serum. The latex reagent will agglutinate in the presence of clinically significant levels of CRP in the serum sample, whilst with normal levels, the latex remains in smooth suspension. The test has been formulated to minimize the possibility of misleading results from “prozone” effects and to virtually eliminate cross reactivity with Rheumatoid Factor. CRP Latex is positive with levels of CRP between 6 and 1000mg/l. The CRP latex test kit is provided with CRP test latex, positive and negative controls, pipette stirrers and an agglutination slide.

RA Latex Test (Non Sample Dilution)

The majority of patients with rheumatoid arthritis have an abnormal protein called Rheumatoid Factor (RF) in their serum. RF is a heterogenous group of IgM molecules directed against the patient’s own immunoglobulins. The Plasmatec RA Latex Test has been developed as a rapid qualitative and semi-quantitative test for the presumptive diagnosis of rheumatoid arthritis. Latex particles, coated with human gamma globulins, agglutinate in the presence of Rheumatoid Factor in serum. Excellent sensitivity (a detection limit of 8 IU/ml) is coupled to the rapid nature of the latex test, with results in just 2 minutes.  The RA latex test kit is provided with RA test latex, positive and negative controls, pipette stirrers and an agglutination slide.

Infectious mononucleosis latex test

Infectious mononucleosis (IM) is an acute infectious disease believed to be caused by the Epstein Barr virus. The infection presents with symptoms of fever, sore throat, malaise, headache and myalgis, generally affecting children and young adults. A diagnosis based on clinical history and symptoms can be difficult therefore a serological test can be very helpful.

Patients with IM have detectable levels of unique heterophile antibodies. The Plasmatec IM latex kit provides a suspension of coated latex particles which will agglutinate in the presence of these antibodies giving a visible reaction. The IMlatex test kit is provided with IM test latex, positive and negative controls, pipette stirrers and an agglutination slide.

Toxoplasmosis latex test

Toxoplasmosis is an infectious disease affecting both animals and humans, which is caused by the protozoan parasite Toxoplasma gondii. Acquired toxoplasmosis is usually asymptomatic and not diagnosed. In pregnant women however, the parasite may cross the placenta to the foetal circulation causing congenital toxoplasmosis. Disease manifestations depend on the stage of foetal development, but can range from spontaneous abortion and prematurity to generalised and neurological symptoms. Toxoplasmosis can also be serious in immunocompromised patients eg with HIV, post-organ transplant.

The Plasmatec Toxoplasmosis latex kit is for the detection of antibodies to Toxoplasma gondii in serum or plasma by slide agglutination. The Toxoplasmosis latex test kit is provided with Toxoplasmosis test latex, positive and negative controls, pipette stirrers and an agglutination slide.

s-LE latex test

Systemic Lupus Erythematosus (sLE) is defined as a prototypic autoimmune disease. The antibodies associated with sLE are those directed against deoxyribonucleoprotein (DNP). These antibodies are believed to cause the formation of the LE cell, occurring in 60-80% of patients diagnosed as having sLE. The Plasmatec SLE Latex kit is a rapid latex agglutination test for the detection of Systematic Lupus Erythematosus (sLE) in human serum by the quantitation of antibodies to Deoxyribonucleoprotein (DNP). The SLE latex test kit is provided with SLE test latex, positive and negative controls, pipette stirrers and an agglutination slide.
