Method Description Describes how the test is performed and provides a method-specific reference
The porphyrins are separated according to numbers of carboxyl units and isomer status. Analytic specificity is based on the combination of chromatographic behavior and the uniqueness of the porphyrins among substances in human specimens in terms of fluorescence spectra. Components quantified are 10 specific porphyrins of isomer series I and III, 4 groups of "isoporphyrins" (isomers other than of series I and III), and protoporphyrin.(Unpublished Mayo method)
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.
