The Laboratory is one of the more advanced features in Quarantine Zone: The Last Check, allowing you to research and discover new symptoms.
Symptoms are key to helping you figure out who is infected and who isn’t. When you unlock more items, you’ll be able to look for different symptoms. However, you’ll also end up with survivors who have unidentified symptoms. That’s where the Laboratory comes in.

How to find new symptoms using the Laboratory in Quarantine Zone: The Last Check
The first task is to look for survivors with completely new symptoms. Once you find one, notice the symptoms they have (both known and unknown). Then, assign them to the Laboratory and follow them there.
When you have multiple survivors with unknown symptoms, you can make some wait in Quarantine. Survivors will always die when you put them in the Laboratory to extract their organs.
How to use the Laboratory in Quarantine Zone: The Last Check
Once you have sent someone to the lab, you’ll find them in a glass cage. Go over to the computer near the cage, and you’ll be able to extract their organs. The infected organs will be highlighted in green, but other organs can block them.
You’ll need to use the laser to destroy the blocking organs. They will be highlighted in yellow. However, don’t destroy any organs highlighted in red. That will automatically fail the process and remove all bonuses you could have obtained.
Once you’ve a clear path to the unblocked organ, you can press the extract button to take it out. This will automatically kill the survivor. The next task is to analyze the organ.
Pick up the extracted organ and drop it in the sample collector. You’ll need to keep holding your LMB while carrying the organ. Click on the collector to start the process. Once done, you’ll get a test tube with organ materials. Put the tube in the analyzer, start the machine, and wait for the results to arrive.
If the survivor was indeed infected, you’ll have a new symptom to check. If not, the process will be a failure, and you’ll end up killing a survivor for no reason. Oops!
