Is it possible to chemically synthesize blood?

Question

Like we know all the chemical compositions of blood and add the ingredients. We even know the compositions of each blood group and synthesize it to be of a particular group, say A - (which is extremely rare). Has blood ever been successfully synthesized in a chemical laboratory and can such blood be used for transplant and function fully as normal blood would?

Answer 1

The simple answer is a resounding NO.

Blood does a lot of different things. The artificial blood that has been produced to date really only carries oxygen and carbon dioxide (not such a bad accomplishment). No artificial blood has yet been produced that can do the other functions of natural blood, such as fighting infection (immune response) and coagulation (blood clotting).
