The CDC sent out a bulletin about its interim guidelines on how to safely deal with specimens from people who might have Ebola. The website includes this diagram of how to properly package and ship, say, a vial of blood to a laboratory capable of testing for Ebola:
Specimens for shipment should be packaged following the basic triple packaging system which consists of a primary receptacle (a sealable specimen bag) wrapped with absorbent material, secondary receptacle (watertight, leak-proof), and an outer shipping package. . . . NO specimens will be accepted without prior consultation. . . . Do not ship for weekend delivery unless instructed by CDC.
