To enumerate HPC cells in peripheral blood as a marker for stem cells, indicating whether or not peripheral blood stem cell harvest (PBSCH) should proceed.
Whole blood EDTA tube
HPC testing is only performed in cases of pre-planned peripheral blood stem cell harvests.
Clotted or underfilled samples can not be tested.
An HPC count of ≥30 cells/μL indicates that PBSCH can proceed without requirement for a CD34 count.
An HPC count of <30 cells/μL indicates that confirmatory CD34 analysis is required prior to commencing PBSCH.
<1 hr – All samples are treated as Urgent
