A collection of devices including a portable, electrically-powered, semi-automated or automated instrument (self-testing meter), reagents, test strips and/or other associated materials and accessories (e.g., control solutions, lancets) intended to be used together for the quantitative measurement of multiple clinical chemistry analytes in a clinical specimen. Analytes detected may include electrolytes, specific proteins, clinical chemistry substrates (e.g., lipid profile), liver and/or cardiac function test analytes, and/or enzymes. It is intended to be used for self-testing by a layperson in the home, and some types may in addition be used at the point-of-care.
