Definitions

• the diagnostic paper strip of this invention may be practically used as follows: the strip is dipped directly into blood obtained from a human or other animal and is kept for a period long enough to permit color development; after washing with water the color developed is compared with standard color chart. In the strip, no contamination and no red change are observed and the content or activity of the component to be determined can be rapidly and accurately determined.
