Panel Components:
CD3, CD4, CD5, CD8, CD45, CD56, TCR-alpha-beta, TCR-gamma-delta

Methodology: FLOW

Clinical Significance:
This tube assesses TCR-alpha-beta and TCR-gamma-delta expression in the T cell population of interest, including looking for aberrant loss of TCR-alpha-beta in abnormal T cell populations. The baseline antibodies in this tube include CD45, TCR-gamma-delta, TCR-alpha-beta, CD3, CD56, CD4, CD5, and CD8.
