T-Cell Activation Profile, CD8 Subsets

CPT 86356(x3); 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.

Test Includes

Percentage and absolute values CD3+, CD3+CD4+, CD3+CD8+, CD3+CD25+, CD8+CD38+, CD8+HLA-DR+, CD4:CD8 ratio; CBC with differential

Use

This test is an expanded profile for AIDS monitoring and prognosis. An increase in activation markers is associated with poor prognosis.

Limitations

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
