An Immunochemical Test is a laboratory test that detects the presence of a substance – or determines the amount of it present – ​​in body samples, using an immunological reaction of the presence of an antigen (protein or polysaccharide), which triggers the formation of an antibody (protein) and can lead to an immune response.

This type of analysis has a high sensitivity and specificity, being the most suitable method to measure substances (analytes) that are usually present in our body in such extremely low concentrations that they cannot be measured accurately by other types of analysis.

For cases of determining the detection concentrations of metabolites whose presence or excess in feces are indicators of physiological problems (Calprotectin and Fecal Occult Blood (FOB), Microbac presents the alternative of an automated Immunochemical detection system.
