Immunophenotyping

Characterization and quantification of benign and malignant cell populations in peripheral blood or bone marrow aspirate and determination of minimal/measurable residual disease (MRD).

Testing material
  • Bone marrow
  • Peripheral blood
Processing time

2 hours to 1 day

Test material

Between 5 and 10 ml of peripheral blood or bone marrow aspirate with heparin as anticoagulant are needed for immunophenotyping. Alternatively, EDTA can also be used as anticoagulant, although it is associated with a faster loss of cell viability. Peripheral blood is sufficient as a test material, provided that malignant cells have infiltrated peripheral blood. Therefore, bone marrow aspirate should be tested if peripheral blood is not infiltrated.

Methodology

Characterization involves multi-parametric flow cytometry (MFC) of the analyzed cell populations based on their light-scattering properties. This procedure uses fluorescence-marked monoclonal antibodies that are targeted at diagnostically relevant antigens on the cell membrane and in the cytoplasm. Modern flow cytometers enable simultaneous detection of several different fluorochromes and hence allow a precise description of antigen expression patterns for approximately 1,000 cells per second. This means that even cell populations with a frequency of 1% or less can be characterized very quickly.
