Abstract
Some embodiments of the invention provide a system comprising a meter and a disposable cartridge for analyzing a fluid sample typically blood that is drawn into the cartridge by capillary action, negative pressure, positive pressure, or a combination thereof. The cartridge has at least one flow path, and includes at least one optical chamber for spectroscopic measurement, and at least one biosensor for biosensor measurement. The meter has a sample slot for receiving the disposable cartridge. The cartridges have electrical output contacts, and the meter slot has electrical input contacts. When the output contacts mate with the input contacts, the optical chamber becomes positioned for spectroscopic measurement. The present invention can provide joint-diagnostic spectroscopic and biosensor measurements.
