Program FL7 is appropriate for laboratories that perform T‑cell subset analysis for immunodeficiency and immune dysregulation. Reporting will include percentages and absolute counts for naïve and memory T‑cells, recent thymic emigrants, TCR alpha/beta and TCR gamma/delta T‑cells, and double negative (TCRalpha/beta+CD3+CD4-CD8-) T‑cells. Participants may include information on additional markers used in their panel to assess memory T‑cell subsets.
