Prolactin, Pituitary Macroadenoma, Serum

Method Description Describes how the test is performed and provides a method-specific reference

The Roche Cobas e immunoassay Prolactin II method employs 2 monoclonal antibodies specifically directed against prolactin. A biotinylated monoclonal antibody and a second monoclonal antibody labeled with a ruthenium complex react with prolactin in the sample to form a sandwich complex. After the addition of streptavidin-coated microparticles, the complex becomes bound to the solid phase via interaction of biotin and streptavidin. Application of a voltage to the electrode then induces chemiluminescent emission, which is measured.(Package insert: Roche E170/Cobas e601/e602 Prolactin II)

 

Dilution of serum sample is performed (10-, 100-, and 400-fold dilution) using manufacturer-recommended diluent and recovery of prolactin is compared to the prolactin concentration in neat sample. Acceptable recovery is defined as 100 + or - 20% recovery after dilution of serum.

PDF Report Indicates whether the report includes an additional document with charts, images or other enriched information

No

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

Same day/1 to 2 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

6 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
