IABCS - Specimen: B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood

Test Catalog

Test ID: IABCS    
B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If immune assessment B-cell subsets test is abnormal, then confirmation will be performed at an additional charge.

 

When multiple specimen types are required to perform a panel of tests, the laboratory will perform the tests for which the appropriate specimen type was received and the laboratory will cancel those for which the appropriate specimen was not received. Please be advised that this may change the degree of interpretation received with the report. If only the refrigerate EDTA sample is received, this test will be canceled and converted to RBCS / Relative B-Cell Subset Analysis Percentage which provides the relative B-cell subset values without quantitation.

Specimen Type Describes the specimen type needed for testing

Whole Blood EDTA

Advisory Information

Two separate EDTA specimens are required: 1 refrigerated and 1 at ambient transport temperature.

 

For serial monitoring, we recommend that specimen draws be performed at the same time of day.

Shipping Instructions

Specimens are required to be received in the laboratory weekdays and by 4 p.m. on Friday. It is recommended that specimens arrive within 24 hours of draw. Specimens arriving on the weekend may be canceled. Draw and package specimen as close to shipping time as possible.

Necessary Information

1. Date of draw is required.

2. Ordering physician's name and phone number are required.

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Specimen Type: Whole blood for TBBS / T- and B-Cell Quantitation by Flow Cytometry

Container/Tube: 4 mL Lavender top (EDTA)

Specimen Volume: 3 mL

Collection Instructions:

1. Send specimen in original tube. Do not aliquot.

2. Label specimen as blood for TBBS / T- and B-Cell Quantitation by Flow Cytometry.

Specimen Stability Information: Ambient <52 hours

 

Specimen Type: Whole blood for IABC / B-Cell Phenotyping Screen for Immunodeficiency and Immune Competence Assessment, Blood

Container/Tube: Lavender top (EDTA)

Specimen Volume:

< or =14 years: 4 mL

>14 years: 10 mL

Collection Instructions:

1. Send specimen in original tube. Do not aliquot.

2. Label specimen as blood for IABC / B-Cell Phenotyping Screen for Immunodeficiency and Immune Competence Assessment, Blood.

Specimen Stability Information: Refrigerated <48 hours

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

TBBS / T- and B-Cell Quantitation by Flow Cytometry: 1 mL; IABC / B-Cell Phenotyping Screen for Immunodeficiency and Immune Competence Assessment: < or =14 years: 3 mL; >14 years: 5 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
