CD8, technical only
Use
CD8 is found on a subset of T-cells deemed normal cytotoxic/suppressor cells, which make up approximately 20-35% of non-diseased human peripheral blood lymphocytes. CD8 is also reported to be present on a subset of natural killer (NK) cells. This test is for technical component only and does not include a pathologist read.
Special Instructions
Not provided.
Limitations
This test only provides the technical component, thus interpretations must be performed separately. Specimens must be fixed in 10% NBF or B plus, and all other fixatives will be rejected. Stated turn-around-times are subject to change based on biopharma protocol requirements and do not include pathologist review.
