505370: T- and B-Lymphocyte and Natural Killer Cell Profile

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.

Test Includes

Percentage CD3⁺; absolute CD3⁺; percentage CD3⁺CD4⁺; absolute CD3⁺CD4⁺; percentage CD3⁺CD8⁺; absolute CD3⁺CD8⁺; percentage CD3^-CD56⁺ natural killer (NK) cells; absolute CD3^-CD56⁺ natural killer (NK) cells; percentage CD19⁺; absolute CD19⁺; CD4:CD8 ratio; CBC

Custom Additional Information

HIV-1 infection results in a decrease of CD4 T cells, an increase in CD8 T cells, a decrease in the CD4:CD8 ratio, and a progressive destruction of immune function. Enumeration of CD4 and CD8 T cells in HIV-1 seropositive patients may be used for prognostic purposes and to monitor disease progression and retroviral therapy. Natural killer (NK) cells are large granular lymphocytes that mediate MHC-unrestricted cytotoxicity against virus-infected and malignant cells and manufacture a number of cytokines following stimulation of the immune system.

Specimen Requirements

Specimen

Whole blood

Volume

Fill tube(s) to capacity.

Container

Lavender-top (EDTA) tube and yellow-top (ACD-A) or (ACD-B) tube

Collection Instructions

Invert tube 8 to 10 times immediately after collection. To preserve cellular viability, collect specimen so it will arrive in the laboratory within 48 hours of collection. Indicate date and time of venipuncture on the tube(s) and on the test request form.

Stability Requirements

Temperature	Period
Room temperature	Yellow-top (ACD-A) or (ACD-B) tube: 2 days Lavender-top (EDTA) tube: 1 day
Refrigerated	Unstable
Frozen	Unstable
Freeze/thaw cycles	Unstable

Reference Range

Reference intervals for adults have been established by the laboratory. See table.
