    摘要: Catheter systems and methods for determining blood flow rates based on light reflection measurements. The catheter may include a lumen extending between a proximal end of the catheter and a distal end of the catheter. The catheter may include fluid infusion openings at the distal end region of the catheter that are configured to permit the indicator fluid to exit the catheter from the lumen. The catheter system may include an optical fiber having one or more sensors thereon for sensing light reflected by blood particles in a body vessel lumen. A blood flow rate may be determined based on the sensed light reflected by blood particles in the body vessel lumen.

    摘要: Multi-phase systems and kits using these multiphase systems are described. The Multi-phase system described herein comprises multiple phase-separated phases each comprises a phase component and the phases, taken together, represent a density gradient. The kit comprising the multiphase system as described herein may be used to separate biological analytes such as cells. Non- limiting examples of the biological analytes include normal erythrocyte with hemoglobin Hb AA, Hb CC, and Hb AS, sickle cell erythrocyte with hemoglobin Hb SS and Hb SC, reticulocyte, iron deficiency anemia red blood cell, &bgr;-thalessemia trait red blood cell, and normal red blood cell.

    摘要: A system and method for analyzing a specimen containing particles that can be difficult to differentiate. The system and method determines a first collective count of a selected group of particles in the specimen, treats at least a portion of the specimen to alter a subgroup of the selected group of particles, determines a second collective count of any of the selected group of particles in the treated portion of the specimen, and subtracts the second collective count from the first collective count to determine a differentiation count for the subgroup of particles altered by the treating of the specimen. The system and method is described with the example of determining concentrations of red and white blood cells in a specimen (e.g. spinal fluid), using auto-particle recognition techniques, without attempting to distinguish and count red versus white blood cells co-existing in the same specimen portion.
