Lipoprotein (a), Serum
Method Description Describes how the test is performed and provides a method-specific reference
This test uses an automated turbidimetric immunoassay method to measure lipoprotein (a) (Lp[a]) in serum. Serum is first incubated with a polymeric enhancer. Following initial incubation and measurement of specimen blank, undiluted antiserum specific to human Lp(a) is added. The specimen solution is mixed and insoluble antigen-antibody complexes begin to form. The complexes that form produce turbidity in the mixture and increase the amount of light scatter. The decrease in percent transmittance of light is measured and is proportional to the amount of Lp(a) in the specimen.(Levine DM, Sloan DJ, Donner JE, et al: Automated measurement of lipoprotein[a] by immunoturbidimetric analysis.

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.
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
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
