Nearly all sapient beings contain blood, in one form or another. The base amount represented in Shiptest is equal to 560 units, and typically remains near this level. Blood levels can be altered through several ways, such as being drawn and injected via syringes and IV drips, bleeding from injuries and regenerated through various reagents. Blood also regenerates slowly over time, and will regenerate faster the more well fed you are. Water, saline-glucose solution, and iron are good alternative ways to regenerate blood faster.

The safe blood threshold for all species is 80% or higher. At 75% you will begin to take oxygen damage, which will eventually outpace your breathing. Below 60%, you will fall into critical condition and begin suffocating. Below 25%, you will be unrevivable without an immediate transfusion.

Blood types are also simulated, and mirror real world blood types listed in the table at the bottom of this section. Humans, Vox, Kepori, Mothpeople and Rachnids all have standard blood types, however other species have their own. Sarathi, Elzuosa and IPCs all have their own unique blood types, incompatible with all other types. Sarathi use Type L Blood, Elzuosa use Type E Blood and IPCs use Coolant. Plasmamen do not have any blood, and do not experience blood loss.

It is important to note, giving the incorrect blood type will lead to rapid build-up of Toxin damage. Remember to always double check the patient's blood type first if you are unsure.
