Test ID: BHSF    
Chorionic Gonadotropin, Beta-Subunit (Quantitative), Spinal Fluid

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

The Beckman Access Total Beta human chorionic gonadotropin (hCG) assay is an automated two-site immunoenzymatic assay. The hCG in the patient specimen is sandwiched between an immobilized monoclonal antibody and a polyclonal rabbit antibody conjugated to alkaline phosphatase. Unbound materials are removed magnetically and a chemiluminescent substrate is added. The resulting light production is directly proportional to the amount of hCG in the specimen and is calculated by means of a stored, multi-point calibration curve.(Package insert: BeckmanAccess Total Beta hCG Kit.

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 Saturday; 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.

1 day

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

3 days

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

90 days

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

Rochester
