Includes:

CD34 % and CD34 absolute count

Turnaround Time:

Routine: 2 hours after receipt in Flow Lab

Test Schedule:

Monday through Friday, 8:00 am to 4:30 pm; Saturday and Sunday 9:00 am to 4:00 pm.

Specimen Requirements:

Apheresis products, peripheral blood samples, cord blood specimens or bone marrow samples in GREEN top (Na Heparin) tube or LAVENDER top (K2-EDTA) tube. Minimum of 1 mL. Room temperature samples are good for up to 24 hours.

Pediatric Specimen Requirements:

Apheresis products, peripheral blood samples, cord blood specimens or bone marrow samples in GREEN top (Na Heparin) tube or LAVENDER top (K2-EDTA) tube. Minimum of 0.5 mL. Room temperature samples are good for up to 24 hours.

Reference Range:

Each patient will have differing number of CD34+ cells depending on the degree of stimulation of their bone marrow.

Comments:

The purpose of this test is enumeration of CD34 positive cells in a sample. Cells positive for CD34 but negative for other markers are the most immature stem cells known presently and can regenerate all of the other hematopoietic cell lines.
