T3 (Triiodothyronine), Total, Serum
Method Description Describes how the test is performed and provides a method-specific reference
The instrument used is a Beckman Coulter DXI 800. The Access Total triiodothyronine (T3) assay is a competitive-binding immunoenzymatic assay. Sample is added to reaction vessel with a stripping agent to dissociate T3 from the binding proteins. T3 in the sample competes with the T3 analogue coupled to biotin for anti-T3 alkaline phosphatase conjugate. Of the resulting antigen: antibody complexes, the T3 analogue:antibody complexes are bound to the streptavidin-coated solid phase. Separation in a magnetic field and washing removes the sample T3:antibody complexes and other materials not bound to the solid phase. The chemiluminescent substrate Lumi-Phos 530 is added to the vessel and light generated by the reaction is measured with a luminometer. The light production is inversely proportional to the concentration of total T3 in the sample. The amount of analyte in the sample is determined from a stored, multipoint calibration curve.(Package insert: Beckman Coulter Ireland Inc, Fullerton, CA, 2009)

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.-12 a.m.
Saturday; 6 a.m.-6 p.m.
