White blood is an artificial blood initially developed for military use.

Haemoglobin, which is found in red blood cells and absorbs and releases oxygen, is normally red. However, the artificial red blood cells developed through nanotechnology that perform the same function as haemoglobin are instead white in color. This literally gives the blood a pale color (and therefore its user a pale complexion), hence the substance's name.

Raiden, having received cybernetic implants by the Patriots, used this kind of blood. After he was badly injured from battling Gekko and Vamp during Liquid Ocelot's Insurrection, he would have died had Naomi Hunter and Sunny been unable to find an infusion of white blood and begin dialysis in time.

Although white blood was outdated by 2018 for use of military cyborgs, white blood in itself was easily accessible for pedestrian cyborgs.[1]

Behind the scenesEdit

Artificial white blood, nicknamed "milk blood," was also featured in Hideo Kojima's Policenauts, in which it was used by members of the military and the BCP's AP Unit. As in Metal Gear Solid 4, it suffers from the same drawbacks, requiring regular hemodialysis treatments.

A type of blood developed to improve the oxygen and nutrient transportation efficiency of blood, as well as to provide a solution to the lack of blood available for transfusions. Based mainly on substances such as perfluorocarbons and fluorescein diacetate, which were used in the latter half of the 20th century for storing organs, it is also called "milk blood", because its red blood cells are white in color. It does indeed possess superior oxygen transportation efficiency and regenerative abilities, but the heavy burden it places on the kidneys makes it necessary for them to be genetically modified and for the user to undergo regular hemodialysis before it can be used for extended periods of time. For these reasons, it is not permitted for medical use among the general public; it is presently only authorized for use within the military and in members of BCP's AP Unit. In addition to milk blood, there is a second-generation powder type made with genetically modified hemoglobin, and a third-generation type containing 100% artificial blood cells, but both of these types are still undergoing clinical trials.
A person using artificial blood has their original blood placed in cryogenic storage and can switch back to it at any time.
Policenauts Glossary[2]

Oxycyte, a perfluorocarbon (PFC) therapeutic oxygen carrier, is a real life "white blood"; boasting an oxygen transfer rate five times that of organic blood. An IV pack is pictured here [1]

In the trailers and promotional materials for Metal Gear Rising: Revengeance, there were blood stains that were red in color, implying that Raiden's cyborg body had its white blood replaced with a more natural-looking substitute. However, the Japanese version has white blood, due to censorship in Japan regarding cutting enemies up.

    • Another reason for switching is that his body wouldn't create its own blood anymore. All Raiden is anymore is a skull and part of a spine, real...

    • I wonder if there will be an option to have the white blood effect in the NA version of the game? 
    • From what I have seen in the demo it wouldn't be. Not to mention I believe they changed raidens blood to jive with his new body. White blood mi...
