Blood Typing
Blood Compatibility & Transfusion
This guide outlines the biological and chemical constraints for blood transfusions on the colony. Transfusion compatibility is determined by three factors in order of priority: Biological Group, Species, and Blood Type.
Biological Groups (Metabolic Compatibility)
Blood cannot be transferred between different biological groups. Attempting to do so will result in immediate rejection, causing the patient to take toxin damage as their body reacts to the foreign proteins.
Note: Nanoblood is an exception to these rules and can be used on any patient.
| Biological Group | Included Species | Blood Reagent | Standard Pack Name |
|---|---|---|---|
| Mammalian | Human, Sablekyne, Kriosan, Naramad | blood | Mammalian blood pack |
| Aquatic | Mar'Qua, Akula | aquatic_blood | Aquatic blood pack |
| Reptilian | Cindarite | reptile_blood | Reptile blood pack |
| Opifex | Opifex | opifex_blood | Opifex blood pack |
| Cht'mant | Cht'mant | chtmant_blood | Cht'mant blood pack |
| Synthetic | FBPs, IPCs | synthetic_blood | Synthetic bag of blood |
| Oil-Based | IPCs / Robots | synth_oil | Synthetic bag of oil |
| Plant | Folken, Mycus | plant_blood | Plant sap pack |
| Slime | Aulvae | slimatic_fluid | Slime fluid pack |
Species Compatibility
Within a biological group, species-specific antigens may still cause minor issues, though the biological group is the primary "hard" barrier.
- Direct Transfusions: Drawing blood from one patient to another is safest when they are the same species. - Processed Blood Packs: General purpose blood packs labeled with the Group name (e.g., Mammalian blood pack) are specially filtered to be compatible with all species within that specific group.
Blood Types (ABO/Rh System)
After matching the biological group, you must match the blood type. While Synthetic and Plant-based lifeforms typically use a universal "X" type, most biological species follow the standard system:
Compatibility Table
| Recipient | Compatible Donor Types |
|---|---|
| A+ | A+, A-, O+, O- |
| A- | A-, O- |
| B+ | B+, B-, O+, O- |
| B- | B-, O- |
| AB+ | Universal Receiver (Can take any type in their group) |
| AB- | A-, B-, AB-, O- |
| O+ | O+, O- |
| O- | Universal Donor (Can give to any type in their group) |
Key Principles
- The Rh Factor: Rh-negative (-) blood can be safely given to Rh-positive (+) patients, but positive blood will cause a reaction in negative patients.
- Emergency Protocol: O-negative is the universal donor. If the patient's type is unknown and they are in critical condition, use O-negative of their correct biological group.
- Incompatibility Effects: If incompatible blood is injected, the patient will suffer from toxin buildup. Keep Anti-Toxins (Dylovene) ready if a transfusion error occurs.
Nanoblood
Nanoblood (and its counterpart, Sanguinum) are highly advanced medical reagents that act as universal blood replenishers.
Unlike standard blood packs, Nanoblood does not contain actual biological cells. Instead, it uses microscopic machines to stimulate the patient's own organs (primarily the kidneys) to rapidly produce the correct type of blood for their biology.
