I think illegal means the act is against the law, no matter what. Unlawful would be an act which is illegal under certain circumstances, but could be legal if procedures are followed. For example, it is illegal to rob, kill, or speed under any circumstances.But, unlawful assembly is perfectly legal if you have a permit. That's what I believe divides the two terms.f something is unlawful it is illegal. ie. if it is against the law, it is illegal.
Northeastern Pennsylvania Region. November 11, 2010. November 5, 2010 - The American Red Cross Blood Services would like to remind donors that receiving a flu shot does not make a person ineligible to donate blood as long as they feel fine at the time of their donation.
The short answer to your question is simply that you do not need to wait until the blood test comes back before going ahead and donating blood. When you donate a unit of blood, the American Red Cross automatically performs a whole bunch of tests on the blood to make sure that the unit is safe and acceptable for use.
