METHOD FOR QUANTIFICATION OF BODY INTERNAL CONCENTRATION OF PROTEIN-BASED DRUG

摘要

It is an object of the invention to provide a method for rapid and accurate quantification of a sample in the human body of a patient. The invention relates to a method for quantification of the body internal concentration of a protein-based drug, comprising step A comprising using a sensing device mounted with a substance binding to a protein contained in the protein-based drug through a specific interaction to determine the binding mass per unit area of a solution containing the protein-based drug to the substance mounted on the sensing device as a standard value and step B comprising assaying a collected biological sample by the sensing device and comparing the resulting value with the standard value to determine the concentration of the protein-based drug contained in the biological sample. In such a manner, the blood concentration of a circulating protein-based drug can be quantified in patient bodies, to determine the optimal dose and enable an effective therapeutic treatment.
