Test ID: HAPB    
Hemophilia A, Molecular Analysis for Inversion, Diagnosis and Carrier Detection

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

Southern blot analysis with the DNA probe 482.6 is used to detect an inversion in a portion of the 3' end of the F8 gene.(Antonarakis SE, Rossiter JP, Young M, et al: Factor VIII gene inversions in severe hemophilia A: results of an international consortium study. Blood 1995;86:2206-2212; Naylor J, Brinke A, Hassock S, et al: Characteristic mRNA abnormality found in half the patients with severe hemophilia A is due to large DNA inversions.

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.

Friday; 12 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.

14 days

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

21 days

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

Whole Blood: 2 weeks (if available) Extracted DNA: 3 months

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