Test run Monday - Friday. Routine turnaround time: ≤11 working days.
Synonyms
Chimerism testing
Post-transplant engraftment monitoring
Sample Type
ACD-anticoagulated whole blood or bone marrow
For other acceptable specimens (e.g., cell suspension, DNA, and cerebrospinal fluid), contact ITL.
Collect
Yellow-top tubes with ACD anticoagulant ACD-A (8 mL) x1 or ACD-B (6 mL) x1
Amount to Collect
8.5 mL in ACD-A tube or 6 mL in ACD-B tube
If these volumes are difficult to obtain, contact ITL at (415) 476-3886 to discuss test needs.
Minimum Volume
Half-full ACD tube (ACD-A or ACD-B); For multiple chimerism tests, collect one full ACD tube instead of two partially filled tubes.
Remarks
Fill ACD tubes completely. ACD-A tube holds up to 8 mL, and ACD-B tube holds up to 6 mL. Obtain ACD tubes from Specimen Receiving. If collected with other chimerism tests and blood counts are low, collect two ACD tubes.
NOTE: Because of limited stability, samples should be collected Monday through Friday avoiding holidays. If samples are collected on Friday, they must be delivered to the UCSF Clinical Laboratory/Central Processing Lab by 5:00 PM.
