Test ID: LRBA    
Lipopolysaccharide-Responsive Beige-Like Anchor Protein (LRBA) Deficiency, Blood

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

The lipopolysaccharide-responsive beige-like anchor (LRBA) protein expression assay is performed on EDTA whole blood. Samples are fixed, permeabilized and stained with antibodies specific for CD45, CD14, CD19, CD3, and CD56 along with either the LRBA antibody (unconjugated) or isotype control (unconjugated). A secondary reporter antibody is added to allow the assessment of LRBA and isotype control expression. Samples are then analyzed on a flow cytometer. LRBA expression is evaluated on the following populations: T-cells: (CD45+CD14negCD3+) and B-cells: (CD45+CD14negCD3negCD19+).(Unpublished Mayo method)

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Monday through Friday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

2 to 4 days

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

4 days

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