Insulin-Like Growth Factor 1, Serum
Method Description Describes how the test is performed and provides a method-specific reference
Testing is performed using the IDS iSYS instrument. The IDS-iSYS Insulin Like Growth Factor-1 is a sandwich, chemiluminescent assay. Samples are incubated with an acidic solution to dissociate IGF-I from the binding proteins. A portion of this, along with a neutralization buffer, a biotinylated anti-IGF-I monoclonal antibody, and an acridinium labeled anti-IGF-I monoclonal antibody are incubated. Streptavidin labeled magnetic particles are then added and following an additional incubation step, the magnetic particles are captured using a magnet. After a washing step and addition of trigger reagents, the light emitted by the acridinium label is directly proportional to the concentration of IGF-I in the original sample.(Instruction manual: Immunodiagnostic Systems Inc.

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.
Monday through Friday; 5 a.m.-12a.m., Saturday; 6 a.m.-6 p.m.
