Follicle-Stimulating Hormone (FSH), Serum
Method Description Describes how the test is performed and provides a method-specific reference
The instrument used is Beckman Coulter Unicel DXI 800. The Access human follicle-stimulating hormone (hFSH) assay is a sequential 2-step immunoenzymatic sandwich assay. A sample is added to a reaction vessel with paramagnetic particles coated with goat antimouse:mouse anti-hFSH complexes and TRIS buffered saline with protein. The hFSH binds to the immobilized mouse anti-hFSH on the solid phase. Materials bound to the solid phase are held in a magnetic field, while unbound materials are washed away. Alkaline phosphatase conjugated goat anti-hFSH is then added and binds to the previously bound hFSH on the particles. A second separation and wash step removes unbound conjugate. 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 directly proportional to the concentration of hFSH in the sample. The amount of analyte in the sample is determined from a stored, multipoint calibration curve.(Instruction manual: Beckman Coulter, Inc., Fullerton, CA, 2010)

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.
