How long does it take for blood to dry outside the body?
Alteration of the ambient temperature has a remarkable effect, as the time needed for the drying process leading to wipe resistance of the droplets decreases to 30 min (time(min)) at an ambient temperature of 24 °C, and is prolonged up to >120 min (time(max)) at an ambient temperature of 15 °C.
