Parathyroid Hormone-Related Peptide (PTHrP), Plasma
Method Description Describes how the test is performed and provides a method-specific reference
The test is performed by an immunochemiluminometric assay by using 2 affinity-purified antibodies from a goat immunized with (1-86) parathyroid hormone-related peptide (PTHrP). One batch of the purified antibody is labeled with acridinium ester as tracer antibodies; a second batch of purified antibody is immobilized onto the bead. When the plasma specimen has PTHrP, the tracer antibodies are linked to the bead via PTHrP and the immobilized antibody.(Wu TJ, Taylor RL, Kao PC: Parathyroid hormone-related peptide immunochemiluminometric assay. Developed with polyclonal antisera produced from a single animal. Ann Clin Lab Sci 1997;27:384-390)
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 Thursday; 1:30 p.m.
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.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
