A latex fixation test, also called a latex agglutination assay or test (LA assay or test), is an assay used clinically in the identification and typing of many important microorganisms. These tests use the patient's antigen - antibody immune response.
MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019. MRSA is any strain of S. aureus that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics.
This test was recommended the standard by the Clinical and Laboratory Standards Institute in 2004 for its use against MRSA. [3] Testing for inducible clindamycin resistance is typically performed in strains of Staphylococcus, β-hemolytic streptococci, and Streptococcus pneumoniae that demonstrate erythromycin resistance and clindamycin ...
The setting of reasonable cutoff limits help reduce false positive results that occur from assay limitations. Because of the social and legal consequences, a positive test result must be confirmed by an alternative method, usually Gas Chromatography/Mass spectrometry.

Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. [2] This concept often is realized in test systems for detecting pathogens, the most common being COVID-19 rapid tests. Very recently such test systems for rheumatology diagnostics have been developed, too. [12]
The diagnosis of vancomycin-resistant Staphylococcus aureus (VRSA) is performed by performing susceptibility testing on a single S. aureus isolate to vancomycin. This is accomplished by first assessing the isolate's minimum inhibitory concentration (MIC) using standard laboratory methods, including disc diffusion, gradient strip diffusion, and automated antimicrobial susceptibility testing ...
The test is usually performed using commercially available test kits which detect the reaction of heterophile antibodies in a person's blood sample with horse or cow red blood cell antigens. These test kits work on the principles of latex agglutination or immunochromatography. Using this method, the test can be performed by individuals without ...
