A method and apparatus for characterizing the type of a blood sample and a variety of blood components are provided wherein a transmission spectrum of the sample is collected over a predetermined wavelength range. For blood typing, this spectrum is then compared with a set of control spectra collected from control blood samples having known blood types, from which the type of the blood sample can be determined. Further methods and apparatus are provided for determining the viability of and for cross matching a platelet unit Additional method and apparatus permit analysis of the sample for the presence of a contaminant, Particles can also be counted in the sample, even when present in low concentrations, including white blood cell.

Spectrophotometric method  for determining the viability of a sample containing platelets

An infectious disease or disorder in a fluid, such as a mammalian blood sample, is detected by taking a transmission spectrum of a test sample in at least a portion of the ultraviolet visible near-infrared and comparing the spectrum with a standard sample spectrum. From the comparison it is then determined whether the fluid from the test sample contains an infectious disease or disorder, and an identity of the infectious disease or disorder is determined. Spectroscopic and multiwavelength turbidimetry techniques provide a rapid, inexpensive, and convenient means for diagnosis. The comparison and determination steps may be performed visually or by spectral deconvolution.
