Analyte

An objective_of_a_protocol is a part_of a protocol

An measure_(measured_analyte) is an objective_of_a_protocol that calls for measuring the substance's abundance within a sample.(realized_as a process in which we use an instrument whose function is to measure the <> substance)

When there is a measured analyte there is a substance that bears a quality and because of the realization of a protocol describing that substance and that quality there comes into being a new role played by that substance which is the role measured_analyte.

An detect_presense_of_analyte_objective is an objective_of_a_protocol that calls for determine the presence or absense of a given type of substance (to a given threshold of detectibility) within a sample.(realized_as a process in which we use an instrument whose function is to measure the <> substance)

A find_glucose_objective is a find_analyte_objective where the analyte is glucose

A concentration_of_substance_quality is a quality that is the ratio of mass of one substance (bearing the analyte_role) of the volume of another substance (bearing the specimen_role) in another. (quality is borne by the specimen)

A concentration_of_glucose_quality is a concentration_of_substance_quality that is the concentration of glucose in a specimen

An analyte_role is <>

We need: How to relate glucose (substance) to the quality? How to relate glucose (substance) to the objective? A: measured_analyte is "about" the bearer of the analyte role
