Answer: Shroud believers maintain that the stains are blood marks from the wounds of Jesus but most test results indicate paint has been used in those areas.
Explanation:
The scientists of the Shroud of Turin Research Project who released their findings in 1988, wrote that the blood stains on the shroud were made of hemoglobin and had albumin as well.
This confirms that these were indeed blood stains and not paint as suggested because both hemoglobin and albumin are substances that are present in the human blood.
