Fibroblast Growth Factor 23 (FGF23), Plasma
Method Description Describes how the test is performed and provides a method-specific reference
The kit uses 2 affinity-purified goat antibodies that bind at the carboxy terminal portion of FGF23. One antibody is coated onto microtiter wells and the other is biotinylated. Horseradish peroxide conjugated to avidin and 3.3', 5,5'-tetramethylbenzidine (TMB) substrate provide the colored product, which is read in a microtiter plate spectrophotometer.(Jonsson KB.

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.
