T- and B-Lymphocyte Differential Profile

Test Number 096917
Test number copied
CPT 86355; 86359; 86360

Test Details

Methodology

Flow cytometry

Result Turnaround Time

1 - 3 days

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Percentage CD3+; absolute CD3+ (T cells); percentage CD3+CD4+; absolute CD3+CD4+ (helper/inducer); percentage CD3+CD8+; absolute CD3+CD8+ (suppressor/cytotoxic); percentage CD19+; absolute CD19+ (B cells); CD4:CD8 ratio; absolute lymphocyte count; CBC with differential and platelet count

Use

This test is used for enumeration of lymphocyte subsets for classification and diagnosis of primary immunodeficiency diseases and for evaluating and monitoring AIDS patients.

Custom Additional Information

Primary immunodeficiencies result from congenital defects of the immune system. Acquired immunodeficiency syndrome (AIDS) results from infection with the HIV-1 retrovirus. The purpose of flow cytometric enumeration is to determine whether select lymphocyte subsets are reduced or absent in order to support the diagnosis of numeric cellular immunodeficiency rather than immunodeficiency due to cellular dysfunction.

HIV-1 infection results in a decrease of CD4 T cells, an increase of CD8 T cells, a decrease in the CD4:CD8 ratio, and a progressive destruction of immune function. In HIV-1 seropositive patients, enumeration of CD4 T cells may be used for prognostic purposes and to monitor disease progression and antiretroviral therapy.
