In DayZ Standalone the Blood stat is a representation of the amount of Blood in your character's body. The amount of Blood a character has is approximately the same as a person in real life with an average adult having between 4,500 mL - 5,500 mL of blood in their body. And, like in life, lose enough of it and your character will die. Along with Health, this is a critical stat to manage.

While loss of Blood from injury isn't quite as frequent as Health and the amount of Blood that can be lost is higher, blood loss overtime from bleeding can quickly stack up. Losing enough Blood can also cause a character to fall unconscious until their wounds are treated.

Blood will natural regenerate over time, but requires the player to be fed and hydrated. There are also medical treatments that can be performed to recover Blood, but even those aren't without risk.

Blood, a core stat in DayZ Standalone, is second only to Health in terms of importance. Representing the amount of blood in a character's body, losing too much Blood can result in unconsciousness or even death.

All Survivors start with 5000 Blood, the maximum that can be had, and lose Blood from injury. While a small amount of Blood is initially lost when a character suffers certain injuries, the primary method of blood loss is bleeding from wounds sustained when a character is injured. Although individual wounds typically do not result in much blood loss, multiple wounds, with varying degrees of severity, can occur in moderate to severe injuries resulting in a high amount of blood loss very quickly.

Blood is a unique stat in a few of ways. First, the effects of blood loss don't happen when it gets close or drops to its minimum value of 0. Instead, the serious effects of blood loss begin to occur around 3,000 Blood, wherein a survivor will begin to take Shock damage until they either fall unconscious or regain enough Blood. Second, Blood is one of only two stats, the other being Health, that cause death to occur when it falls below a specific value. With Blood, a character only needs to lose ~2,500 Blood for death to occur. Finally, Blood is unique in that every character has a blood type, which is randomly determined when the character is first spawned. A character's blood type is unique to that character and does not transfer when a new character is spawned.

As long as a Survivor remains moderately fed and hydrated, they will regenerate lost Blood automatically. While the natural recovery process is faster than it is with Health, the larger amount of Blood a character has makes the recovery time approximately the same. Unlike Health, there are medical treatments a character can receive to increase recovery speed, via Saline Bag IV, or even instant restore lost Blood, via Blood Bag IV. Caution is advised, however, as an improper Blood Transfusion can result in the Hemolytic Reaction.


Blood Type[edit | edit source]

A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. In DayZ Standalone every character is randomly given a specific blood type on character creation. This blood type is unique to that character, does not transfer when a new character is spawned and is not carried over to other characters created on separate hives. A character's blood type affects their ability to donate or receive blood transfusions.

Getting Blood Type[edit | edit source]

A character's blood type can be determined by using a Blood Testing Kit. The kit can be used either on yourself or another Survivor. Once complete, the character's blood type will be permanently displayed in the HUD along the upper-right corner of the Blood icon.

Donating Blood[edit | edit source]

Survivors can donate their Blood to be used in Transfusions for other injured Survivors. Using a Blood Bag Kit on yourself or another Survivor will, by default, fill the Blood Bag Kit with 500 mL of that character's Blood. The donor will immediately lose 500 Blood, so caution is advised. As of 1.0, the action of collecting Blood with a Blood Bag Kit is continuous. Meaning, the action will continue until you stop or move, the donor moves or the blood bag fills up. Stopping before it completely fills will result in a partially filled blood bag (with the amount dependent on how long the action was performed). Additionally, collecting Blood is affected by the Soft Skills system. Survivors with a high level of Precision are able to collect more without the donor losing as much (e.g. a Survivor with a high level of Precision is able to fill up the 500 mL blood bag with the donator only losing 450 Blood instead of the normal 500 Blood).

Transfusions[edit | edit source]

Once a Blood Bag Kit has been filled, it will need to be combined with an IV Start Kit to make a Blood Bag IV. The Blood Bag IV can then be used to perform a blood transfusion on an injured Survivor, instantly restoring '500 Blood. In order to perform a successful blood transfusion, the donor's blood type must be compatible with the recipient's. It's imperative to check blood type compatibility before performing a blood transfusion, as transfusion with incompatible blood type will result in the often fatal Hemolytic Reaction.

As with collecting blood, performing a transfusion is a continuous action. Meaning, the action will continue until you stop or move, the recipient moves or the blood bag is emptied. Transfusions are also subject to the Soft Skills system. Survivors with a high level of Precision are able to transfuse the recipient with more blood per mL from a Blood Bag IV. (e.g. a Survivor with a high level of Precision is able to transfuse 550 Blood from a 500 mL blood bag instead of the normal 500 Blood).

Possible blood types and their associated compatibility can be found on the table below.

  2. AB+ is the universal recipient; can receive from anyone without checking.
  3. O can transfer to O, A, B or AB
  4. A can transfer to A or AB
  5. B can transfer to B or AB
  6. AB can only transfer to AB
  7. (-) can transfer to (-) or (+)
  8. (+) can only transfer to (+)


Losing Blood[edit | edit source]

In most situations where a Survivor has been injured Health tends to be the immediate concern as the instant damage received is much greater. Loss of blood not forgotten bleeding multiple wounds quickly add up etc

Bleeding[edit | edit source]

 See Also: Bleeding

The most common method of losing Blood is Bleeding from wounds received during an injury. While a character is bleeding, they lose a certain amount of Blood per second until the wound is bandaged or clots on its own. How much Blood is lost depends on the severity and location of the wound. Characters can also sustain multiple wounds with each wound causing additional blood loss. In the event a Survivor receives multiple wounds, each one will have to bandaged to completely stop the bleeding.

Characters can be wounded anywhere on their body with the location of the wound largely affecting the amount of Blood lost from bleeding. Typically, wounds to the hands or feet will cause less blood loss than wounds to the arms and legs, which themselves cause less blood loss than wounds to the head and torso.

Wound Severity Locations Blood Loss*
per minute
Total Blood Loss
Minor Hands, Feet 36 180
Moderate Arms, Legs 216 1080
Severe Torso, Head 360 1800
Clot Time: ~5 minutes

*Values are approximate averages and depend on several other factors

Injury[edit | edit source]

Occasionally Blood can be lost from an Injury itself. Though not nearly as common as bleeding and often in small amounts, Blood loss from injury occurs instantly as it does with Health. It should be noted that Blood damage is seperate from bleeding and injuries that cause Blood damage can also cause a Survivor to begin bleeding as well. Below are the two most common injuries that cause Blood damage and their associated average damage.

Injury Blood Loss*
Stab Wound 100
Gunshot Wound 100
