Abstract: Disclosed are devices, components and methods associated with a body fluid analysis system, which, according to some embodiments, can be employed in at-home, clinical, medical office and outpatient settings and applications. The system can be configured to provide results within a short period of time after a body fluid sample has been acquired from a patient such as by a finger or skin prick. In some embodiments, a body fluid sample cartridge is configured for use in conjunction with a corresponding spectroscopic body fluid analysis device, where the cartridge comprises one or more body fluid dispersing sheets, layers or membranes. In some embodiments, the cartridge is configured to deliver and disperse a predetermined amount or volume of a body fluid sample taken from a human or animal onto, into, through or across the body fluid dispersing sheet, layer or membrane disposed within the cartridge for subsequent analysis of the body fluid sample by a corresponding spectroscopic device.
