Comments: |
Specimen should be collected as soon as possible. In the case of a
recently deceased infant (< 24 hours) a blood specimen from a cardiac
puncture usually gives a good result. Skin and other tissues obtained
more than 48 hours post-mortem have a markedly decreased success rate
of cell growth for cytogenetic analysis.
I. Peripheral blood:
-Collect 5-10 cc adult, 2 cc infants of blood in a green-top
vacutainer with sodium heparin. Invert tube to mix well. DO NOT
FREEZE OR CENTRIFUGE.
-Deliver specimen to the Cytogenetics Lab (W-101, GH) as soon as
possible during work hours (Monday through Friday, 0800-1700).
II. Skin, fetal tissue, diaphragm tissue, tumor tissue, other tissue:
-Call the Cytogenetics lab for specimen transport tubes with
media. If special transport media is not available, sterile
Ringers lactate solution can be used.
-Specimen should be obtained aseptically. Do not put specimen in
alcohol or formalin. Do not freeze or flame or refrigerate.
-In cases of abortion, don't send intact fetus. Send only tissue
specimen to the lab (skin, diaphragm, lung, etc).
-Label the tube(s) with patient name and medical record number (there
should be two identifications).
-Specimens should be sent at room temperature.
Also call the lab at 319-356-3877 with any questions.
