Human Factors
We were flying a parcel of contaminated blood. The box had the UN1845 on it as well as the Dangerous Goods Form. I thought about it and felt it was correct. Later that evening after signing off duty and the next day I was thinking that the parcel should have also had a UN3373 as well as a category B bio substance label. I only saw the Dangerous Goods Form and parcel that was labeled UN1845.I saw the parcel and inspected it and it's associated paperwork during preflight.Possible incomplete labeling of HAZMAT.At the time I looked the information up in the Dangerous Goods manual as well as online and determined in the short time we had that it only needed the UN1845 and nothing else. The more I thought about it however; I feel that it may should have had the UN3373 and cat B bio labels as well.[More correct procedure];verify with the manuals and if still not sure; discuss it with Dispatch or the Chief Pilot.
Air Carrier First Officer reported the transport of Hazmat cargo with incomplete required Hazmat labeling.
