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

Testing is performed using the Roche Cobas e601/602. The Roche Progesterone III assay is a competitive immunoassay using electrochemiluminescence detection. Patient specimen and biotinylated progesterone-specific antibody are incubated to produce immunocomplexes. The amount of immunocomplexes formed is dependent on the progesterone concentration in the sample. Then, streptavidin-coated microparticles and a progesterone derivative labeled with a ruthenium complex are added to the reaction mixture and occupy the open sites still present on the biotinylated antibodies by formation of an antibody-hapten complex. The entire complex becomes bound to the solid phase via interaction of biotin and streptavidin. Next, the reaction mixture is aspirated into measuring cell where the bound microparticles are magnetically captured onto the electrode surface and unbound substances are removed. Voltage is applied to the electrode inducing a chemiluminescent emission which is then measured against a calibration curve to determine the amount of progesterone in the patient specimen.(Package insert: Roche Progesterone III.

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 Sunday; Continuously

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

1 day

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

7 days

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