Abstract
An integrated bodily fluid sampling device includes a lancet, a test strip attached to the lancet, and a flexible sheet extending from the test strip. The lancet and the flexible sheet form a gap sized to draw bodily fluid onto the test strip via capillary action. Further, a sampling end portion of the flexible sheet is shaped to enhance capillary action of the sheet. In one form, a removable film covers the lancet and forms a seal with the flexible sheet such that the seal surrounds a lancet tip. In another form, an insulating layer covers a portion of the lancet to prevent electrical interference between the lancet and an electrical testing system on the test strip and ensure an accurate analysis of the bodily fluid.
