Test Catalog

Quantification/viability of CD34 and CD45 ISHAGE

Clinical information

Diagnostic Utility:

This test quantifies:

  • cells positive for the CD34 membrane receptor (hematopoietic progenitors)
  • cells positive for CD45 (common leukocyte antigen)

and determines cellular viability. It is a determination used as quality control for units of umbilical cord blood and products for hematopoietic progenitor transplantation.

Method

Flow Cytometry.

Reference Values

The results are quantitative. CD34 and CD45 concentrations can vary significantly depending on the type of sample/product and whether they come from a healthy donor or a patient. As for cellular viability, the expected values are as follows:


 

Sample CD45 Viability CD34 Viability
Fresh CB ≥85% ≥85%
Thawed CB ≥40% ≥70%
Fresh/Thawed Progenitors ≥70% ≥70%

Diagnostic Algorithm:

Not applicable.

Turnaround Time:

1 day.

Specimen information

Sample: Peripheral blood, umbilical cord blood, bone marrow, apheresis.
Tube: EDTA K3 tube (peripheral blood) or tube without additive (anticoagulated samples).
Minimum volume: 100 µL

Stability:

  • At room temperature: 1 day
  • In refrigeration: 1 day
  • Cryopreserved between -156oC and -196oC: 20 years

Transport instructions: Preferably peripheral blood at room temperature; umbilical cord blood, bone marrow, apheresis refrigerated.

Reason for rejection: Sample highly hemolyzed or with clots.
