Processing and Shipping
|Specimen Processing:||Store at room temperature. Do NOT refrigerate or freeze.|
|Shipping Instructions:||Ship at room temperature. Must arrive within 24 hours.|
|Test Performed at or Referral Lab||Cytogenetics (UMMC-East Bank)|
|Use:||Useful for the differential diagnosis between idiopathic aplastic anemia and Fanconi anemia. After treatment with similar doses of bifunctional alkylating agents such as Diepoxybutane (DEB) or Mitomycin C (MMC), Fanconi anemia patients will typically show a greater than 50-fold increase in rates of chromosome breakage compared to concurrent controls or other aplastic anemia patients.|
Store at room temperature and contact Cytogenetics Laboratory (lab or voice mail at 612-273-3171) for specimen pick up as follows:
· During regular hours: (Mon-Sun, 0800-1700): telephone laboratory whenever specimens are sent.
· After regular hours: leave voice mail to indicate specimen has been sent or has arrived.
