- Animal: Studied in the medical arts that deal specifically with the prevention and treatment of disease and injuries to animals. Includes extensive knowledge of their anatomies, patterns of behaviour, and products derived from them.
- Human: Advanced training in treating disease and injuries in Humans. Used for first aid, stabilising the heavily injured, and stopping bleeding. Despite the name, it will work on Abhumans such as Ratlings, Ogryns, and Kin of the Leagues of Votann.
- Forbidden (Various, Restricted): Examples include knowledge of the installation and configuration of various radical Augmetics. Advanced medical training in treating disease and injuries in a specific species of xenos creature — typically used after a battle to stabilise one of them long enough for interrogation. Knowledge of diseases borne of the warp. Each Forbidden Medicae requires taking a corresponding Forbidden Knowledge Talent in order to learn it.
Medicae represents knowledge of proper medical treatments, both in the field and in a fully equipped hospital. Immediate response to trauma can be a huge factor in recovery, and so recognising and appropriately treating an injury in the field — a wound, a burn, or a xenos poison — is often the difference between a minor inconvenience and an early grave. Most agents have basic training in first aid, but some are prepared to deal with far more complex injuries. Of course, not everyone who receives training is able to put those skills into practice in the field.
