Method Description Describes how the test is performed and provides a method-specific reference
Ion selective electrode (indirect potentiometry). The ISE module of the P-Module performs indirect measurement of electromotive for (EMF). The ISE module measure the EMF difference between an ion selective electrode and a reference electrode. The EMF of the ion selective electrode is dependent on the ion concentration of the sample. The EMF of the reference electrode is constant. The P-Module uses an electronic calculation circuit to convert the EMF of the sample to the ion concentration of the sample.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
