Test info

  
CD43 by IHC
  
12376 - Technical only, 12379 - Technical & interpretation
  
LAB12376
LAB12379
  
Leu22
  

All IHC stains will include a positive control tissue

  
  • Approximately 90% of peripheral T cell lymphomas are positive for Leu22
  • However, its disadvantage is that 30-40% of B cell NHL are also Leu22 positive
  • Approximately 90% of myeloid leukemias are positive for Leu22
  • The combination of CD20 positive and Leu22 positive lymphoid populations is diagnostic of malignant lymphoma
