A kit of components for extracting and storing a skin tissue sample includes an extraction cartridge with a plurality of blades, an actuator cartridge, and a cap with an aqueous preservative. The actuator cartridge is removeably attached to the extraction cartridge and causes the plurality of blades of the extraction cartridge to extract a skin tissue sample from the person. After the skin tissue sample is extracted, the cap is attached to the extraction cartridge to store and suspend the skin tissue sample in an aqueous preservative preloaded in a container in the cap. A liquid-tight seal prevents bodily fluids from contaminating the actuator cartridge and this enables the actuator cartridge to be removed from the extraction cartridge and to be reused. The extraction cartridge and the attached cap, which store the skin tissue sample, are sent to medical laboratory so that the skin tissue sample can be analyzed.
