The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.
