Test ID: LDLM    
Familial Hypercholesterolemia, LDLR Large Deletion/Duplication, Molecular Analysis

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

Multiplex ligation-dependent probe amplification (MLPA) is used to detect the presence of large genomic deletions and duplications of all 18 exons and the promoter of LDLR. MLPA requires the hybridization of 2 adjacent probes to each exon; these probes are then amplified by PCR. Deletions are seen as decreased signal relative to control probes arising from the deleted LDLR exon(s), while duplications result in increased signal.(Package insert: SALSA MLPA Kit P062B LDLR, MRC Holland)

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.

Varies

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.

5 days

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

10 days

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

2 months (extracted DNA only is saved)

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

Rochester
