Abstract
A method and apparatus for detecting hemolysis from a sample of a patient's blood. A sealed chamber having a fixed volume is provided for receiving the sample of blood. The sealed chamber has an internal pressure resulting form a presence of a fixed quantity of air inside the chamber. A volume of fluid that includes the sample of blood is received into the sealed chamber. While the sample is being received into the sealed chamber, the internal pressure of the sealed chamber is raised to an increased internal pressure by retaining the fixed quantity of air inside the sealed chamber as the fluid is received into the chamber. The increased internal pressure causes the plasma portion of the blood sample in the chamber to permeate a membrane that forms at least a portion of one side of the chamber. A test volume of the plasma portion of the sample is received by a hemolysis detection means after the test volume of the plasma portion has permeated the membrane, and a hemolysis condition is detected in accordance with a hue associated with the test volume received into the hemolysis detection means.
