The evaluating results of the diagnostic characteristics of an immunochromatographic test for the detection of fecal occult blood (hemoglobin) were presents in the article. The test was approved samples without hemoglobin and model samples containing of standardized preparation of hemoglobin in various concentrations in comparison with two immunochromatographic test systems. The developed test system identified hemoglobin in concentrations higher 50 ng/ml in 99,2% cases, the specificity of the analysis was 98,1%. The obtained levels of sensitivity and specificity were higher the similar parameters for the compared test systems. The immunochromatographic FOB-test can be used for rapid analysis in the primary screening of colorectal cancer.

Human schistosomiasis is a chronic neglected tropical disease caused by blood flukes of the genus Schistosoma, infecting 250 million people worldwide, mostly in sub-Saharan Africa. Recently, thousands of cases have been reported in immigrants to non-endemic countries, including Italy. Serological screening is recommended but so far, no accurate point-of-care (POC) and lab-free test is available.

The COVID-19 outbreak was an important turning point in the development of a new generation of biosensing technologies. The synergistic combination of an immunochromatographic test (lateral flow immunoassays, LFIA) and signal transducers provides enhanced sensitivity and the ability to quantify in the rapid tests. This is possible due to the variety of nanoparticles that can be used as reporter labels.

Antibiotic-resistant bacteria are usually found in food-producing animals worldwide. Ciprofloxacin, an antibiotic, can lead to antibiotic residues in food products, posing health risks to consumers and contributing to the development of antimicrobial resistance. Foodborne illnesses occur when adequate attention is not paid to food hygiene and safety, raising the potential for resistant bacteria to spread to humans through the food chain.

(PCV2) is the main and primary causative agent of Postweaning Multisystemic Wasting Syndrome (PMWS). To date, immunoperoxidase monolayer assay (IPMA), indirect immunofluorescent assay (IFA), and enzyme linked immunosorbent assay (ELISA) are the most commonly diagnostic methods for detecting PCV2 antigens. However, these methods require specialized equipment and technical expertise and are suitable for laboratory use only.

In this study, a novel rapid immunochromatographic (IC) test for African swine fever virus (ASFV) antibodies is presented. An immunochromatographic test (IC) is a detection technique that combines membrane chromatography with immunolabeling. This approach saves time for antibody preparation, resulting in a shorter production cycle.
