Abstract: A single, integrated device in which a body fluid (e.g., blood) of a human or animal can be both collected and analyzed easily and without risk of contamination is disclosed. The collection portion and analysis portion of the device are permanently joined to permit movement of small quantities of body fluid under controlled conditions, to minimize any waste of the body fluid, to ensure that no contamination reaches the main body fluid volume, and to create a permanent physical record of the results of the analysis in association with the fluid sample itself: A wide variety of different body fluid components which may be indicative of various diseases, dysfunctions and abnormalities of the human or animal or the body fluid itself can be tested for.
