==Modifying Symptoms==
To obtain a new [[#Symptoms_Table|symptom]] you need to mutate an existing virus. This involves adding a chemical to the virus, which will generate a new symptom. Rarer and harder to acquire chemicals will yield more potent symptoms. You will start with enough chemicals to create a powerful disease, as long as you use them carefully. You can also insert an isolated symptom into your main virus, by moving 1 unit of the isolated culture to the main mix with a dropper. It will not work every time and may need to be repeated a few times. 

====Basic chemicals====
These are the basic chemicals for virus mutation. You can either add them directly to a virus to obtain a random level symptom, or mix them with other ingredients to get [[Guide_to_chemistry#Virology_Recipes|advanced chemicals]], that will give you a specific level symptom.

* '''[[Virus Food]]''': You can make virus food with Water and Milk. Virology lab has its own Virus Food Dispenser. Mixing this with a disease will give that disease a symptom of level 1 to 2.
* '''[[Unstable Mutagen]]''': You can use mutagen to mutate your disease and give it a symptom of level 2 to 4. Virology starts with a 30u bottle of mutagen.
* '''[[Plasma|Liquid Plasma]]''': Plasma can be used to mutate your disease to give it a symptom of level 4 to 6. Plasma in liquid form is generally in very limited supply, unless mining and chemistry cooperates with you. Virology starts with a 30u bottle of liquid plasma, and in some station layouts with extra plasma bars.

====[[Guide_to_chemistry#Virology_Recipes|Advanced Chemicals]]====
Using these will allow you to both save time and resources when trying to acquire the symptoms you want.

* '''[[Guide_to_chemistry#Virus Rations|Virus rations]]''': Virus rations can be used to mutate your disease and give it a level 1 symptom. It is made by depleting Virus food with Synaptizine.
* '''[[Guide_to_chemistry#Mutagenic Agar|Mutagenic Agar]]''': Mutagenic agar can be used to mutate your disease to give it a level 3 symptom. It is made by mixing Unstable mutagen and virus food together.
* '''[[Guide_to_chemistry#Sucrose Agar|Sucrose Agar]]''': Sucrose agar can be used to mutate your disease to give it a level 4 symptom. It is made by mixing Sugar or Saline Glucose Solution and Mutagenic agar together.
* '''[[Guide_to_chemistry#Weakened Virus Plasma|Weakened Virus Plasma]]''': Weakened virus plasma can be used to mutate your disease and give it a level 5 symptom. It is made by weakening virus plasma using Synaptizine.
* '''[[Guide_to_chemistry#Virus Plasma|Virus Plasma]]''': Virus plasma can be used to mutate your disease and give it a level 6 symptom. It is made by mixing liquid plasma with virus food.

====Uranium Gels====
These chemicals require large quantities of liquid uranium (obtained by grinding uranium bars). You'll require the help of mining to make these.
* '''[[Guide_to_chemistry#Decaying Uranium Gel|Decaying Uranium Gel]]''': Decaying Uranium Gel can be used to mutate your disease and give it a level 6 or 7 symptom. Despite its name, it will not decay into nothingness or deplete itself over time (outside of circumstances that would cause normal chemicals to do that). It is made by combining 1 virus food with 1 liquid Uranium.
* '''[[Guide_to_chemistry#Unstable Uranium Gel|Unstable Uranium Gel]]''': Unstable Uranium Gel can be used to mutate your disease and give it a level 7 symptom. It is made by combining 1 virus plasma with 5 liquid Uranium.
* '''[[Guide_to_chemistry#Stable Uranium Gel|Stable Uranium Gel]]''': Stable Uranium Gel can be used to mutate your disease and give it a level 8 symptom. It is made by combining 1 plasma with 10 parts liquid Uranium and 10 parts liquid silver or gold.

====[[Guide_to_chemistry#Synaptizine|Synaptizine]]====
Synaptizine, aside from being a base chemical, will remove one random symptom to any virus it comes in contact with. It's important if you intend to isolate a specific symptom. For example, if you mutate your Cold virus and it acquires the Toxic Filter symptom, you can try and add synaptizine to it to create a virus which only has the Toxic Filter symptom.

====[[Guide_to_chemistry#Formaldehyde|Formaldehyde]]====
Formaldehyde will neuter one random symptom when mixed with a virus. This disables its effects while keeping the attributes intact. This is useful for meeting threshold values without making the virus deadly.
