FAQs

What is a kPlex?

kPlex, short for kinetic multiplexing, is an official MONDIALAB Research and Development product term. The MONDIALAB PRO kPlex is the consumable LFIA testing module of the MONDIALAB PRO platform, consisting of plastic components, 4 LFIA holders (with a barcode, side symbol, and sample-well), a connector and a handle. 

What is a lateral flow test?

Also known as lateral flow immunochromatographic assays (LFIA), lateral flow tests are simple cellulose-based devices that are intended to detect the presence of a target analyte in a sample (blood, urine, feces, plasma, etc.) without the need for specialized and/or costly equipment. Learn more >

What does LFIA stand for?

LFIA is an abbreviation for lateral flow immunochromatographic assays.

What is a reagent?

A reagent is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs. The terms reactant and reagent are often used interchangeably — however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates. Learn more >

What is an assay?

An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount or functional activity of a target entity (the analyte). Learn more >

What is a biomarker?

A bio-marker, or biological marker is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Biomarkers are used in many scientific fields. Learn more >

What does immunochromatographic mean?

Immunochromatography is when a capture antibody is immobilized onto the surface of a porous membrane, and a sample passes along that membrane. The analyte in the sample is bound by the antibody which is coupled to the detector reagent. Learn more >

What are antibodies?

Antibodies also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. The antibodies attach, or bind, themselves to the antigen and inactivate it. Learn more >

What is an antigen?

A foreign substance or a toxin which induces an immune response in the body, especially in the production of antibodies. Learn more >

What is IgG?

Immunoglobulin G (IgG), the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections. Learn more >

What is IgM?

Immunoglobulin M (IgM), which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection. Learn more >

What is cross-reactivity?

Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. In immunology, the cross-reactivity has a more narrow meaning of the reaction between an antibody and an antigen that differs from the immunogen. A few examples of cross-reactivity have been confirmed in humans, one of which involves influenza virus-specific CD8+ T cell and hepatitis C virus antigens

What is POCT?

Point-of-care testing (POCT) is defined as medical diagnostic testing at or very near the point-of-care, that is, at the time and place of the patient care. Learn more >
