• tubes
  • Micro-hematocrit tubes available in multiple sizes and additives for a wide range of capillary blood collection. (bio-medicine.org)
  • Through differential spectrophotometry, the differences in optical densities of a blood sample flowing through small-bore glass tubes at isosbestic wavelengths for deoxyhemoglobin and oxyhemoglobin and the product of the luminal diameter and hematocrit create a linear relationship that is used to measure hematocrit levels. (wikipedia.org)
  • value
  • For example, a hematocrit value of 40% means that there are 40 milliliters of red blood cells in 100 milliliters of blood. (labtestsonline.org)
  • Of the two, the hematocrit value requires less specialized equipment and is the quicker option, according to "Clinical Methods: The History, Physical, and Laboratory Examinations. (reference.com)
  • model
  • Hematocrit is then determined by comparing this spectrum to a mathematical model relating optical properties to blood Hematocrit. (google.ca)
  • 5. A method of claim 1, wherein the mathematical model comprises a non-linear mathematical equation relating hematocrit to the reflectivity of the plurality of red blood cell constituents. (google.ca)
  • 15. A method of claim 1, wherein the processing includes comparing the optical spectrum with the mathematical model to determine blood hematocrit. (google.ca)
  • Using an experimental model of elevated hematocrit in healthy mice, we measured effects of hematocrit in two in vivo clot formation models. (bloodjournal.org)
