The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →To detect symptoms in Quarantine Zone: The Last Check, inspect each survivor from all sides, use the tool suited to each finding, compare results with the symptoms currently available in the in-game menu, and select every symptom you observe. A correct decision about where to send someone may not be enough for a strong inspection grade if you miss or fail to record findings.
The tool and category details below are drawn mainly from a third-party guide, not an official symptom encyclopedia. Treat them as practical guidance that may change with updates; the game’s own unlocked symptom list is the reference to follow during play.
How to inspect a survivor for symptoms
- Make a full visual pass. Walk around the survivor and inspect the front, sides, back, under the arms, and feet. Crouch to see low or obscured areas. A flashlight can help distinguish similar marks in dim light.
- Check for behavioral clues. Coughing, sneezing, hiccupping, or holding the stomach may draw attention to a possible issue. These cues come from a fan-made guide and should prompt further examination, not replace it.
- Use the available examination tools. Hidden, internal, or tool-specific findings may not be visible on the skin. Match the tool to the kind of result you need to check, using the reference below.
- Compare results with the current in-game symptom list. The available tools and symptoms expand as you progress. Use the unlocked list rather than assuming every symptom can be identified at the start.
- Record every finding. Select the observed symptoms in the symptom menu before completing the inspection. A Steam Community discussion reports that omitted findings can lower the grade even when the player makes the correct routing decision.
- Choose the destination based on the game’s category and scenario. Steam’s official description says suspicious cases can be sent to quarantine or the lab, while healthy survivors go to the living block. Follow the screening options presented in your current situation.
Which tool detects each kind of finding?
This reference summarizes the tool descriptions in PC Gamer’s January 14, 2026 guide. It is third-party guidance, not a complete official tool manual.
| Tool | Findings described | How to use the result |
|---|---|---|
| Scanner | Bruises, bites, necrosis, rashes, and cuts | Scan the whole body, including low and obscured areas. Use a flashlight when marks are difficult to distinguish. |
| Thermopulsometer | Temperature and heart rate | Compare the displayed readings with the symptom categories in your current game list. |
| Reflex hammer | Limb reactions | Watch the response carefully, then mark the corresponding finding if it appears in the menu. |
| Stethoscope | Breathing sounds such as wheezing and growling | Use it to investigate possible chest or breathing symptoms. |
| X-ray | Internal bleeding, mold, and foreign objects | Use it for findings that a surface inspection cannot reveal. |
| Matioscope | Eye bacteria and parasites | Examine the eyes when the symptom list or inspection prompts call for it. |
| UV light | Infection signs on bodies or belongings | Check the relevant body area or belongings when UV detection is indicated. |
How the game’s symptom categories differ
PC Gamer’s guide groups example findings into three in-game categories. These are fictional game classifications, not real medical guidance, and the guide’s list may not cover every symptom or remain current after updates.
Recommended Free Tools
| In-game category | Examples listed by PC Gamer | Guide’s readings |
|---|---|---|
| Safe | Yellow eyes, freckles, herpes, red skin, bruises, and nosebleed | Temperature below 37°C; heart rate below 120 BPM |
| Quarantine | Conjunctivitis, skin rash, pale skin, red bruise, skin cuts, mouth bleeding, and aggression | Temperature 37–41°C; heart rate 120–180 BPM |
| Liquidation | Red eyes, green skin, bite mark, necrosis, eye pus, and nose pus | Temperature 41–45°C; heart rate 180–200 BPM |
The temperature and heart-rate ranges above are the guide’s reported values, not independently confirmed official specifications. Check your in-game symptom list and readings rather than treating these ranges as medical thresholds.
Why a correct decision can still earn a poor inspection grade
In a January 13 Steam Community discussion titled “Poor Inspections Randomly,” players describe receiving a poor grade despite sending an obviously infected survivor to the lab. A commenter says the manual describes “Poor Inspection” as below 50% of symptoms listed, a regular inspection as above 50%, and an “Excellent inspection” as above 75%.
Rank #2
- Quarantine
- Liquidate
- Survival
- Arrange Food
Those thresholds are community-reported, not an official developer statement, and may have changed. The practical lesson is to record each symptom you can identify instead of relying only on the final routing decision. The same discussion reports that early inspections can be confusing when a symptom is not yet detectable with the tools available to the player; this is player experience, not a confirmed universal rule.
Distinguishing similar marks and avoiding missed findings
Bruise or necrosis?
PC Gamer notes that these marks can look similar in low light. Its guide describes necrosis as darker and cooler-toned, while a red bruise appears deeper purple. Use a flashlight and check the scanner rather than deciding from a quick glance.
Rank #3
- Intense Survival Missions
- Deadly Outbreak Enemies
- High-Risk Zones
- Upgradeable Combat Gear
Visible clues are not the whole inspection
A surface check can miss internal findings, sounds, eye findings, reactions, or signs revealed by UV light. Work through the tools available to you and inspect concealed areas before you finish.
Symptom categories are game mechanics
Labels such as “Safe,” “Quarantine,” and “Liquidation” describe the game’s screening system. They are not real-world medical classifications or diagnostic advice.
Rank #4
- Realistic quarantine zone
- Intense survival missions
- High-alert security checks
- Immersive 3D environments
- AMAZING BOSS
