(under the class definition) Processes or compositions, for performing clotting tests and factor level tests.
(1) Note. Examples of the tests included here are: P.T. Prothrombin time, APPT. Activated partial prothrombin time, T.T. Thromboplastin Test, P.P Prothrombin and Procovertin Test

73, Measuring and Testing,
61.65+, for testing the settling rate of liquid suspensions of solids.
356, Optics: Measuring and Testing, particularly
40+, for a transmissive, or reflective optical measurement or test performed on blood such as statistical counting of blood component particles, determination of hemoglobin content or determination of oxyhemoglobin in blood. 359, Optics: Systems (Including Communication) and Elements, for the counting of blood cells or particles one by one.
377, Electrical Pulse Counters, Pulse Dividers, or Shift Registers: Circuits and Systems,
10+, for particle counters with or without the sizing of the particles counted.
422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing,
73, for apparatus for carrying out the process of this subclass.
516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or there is no art class. Class 516 provides for compositions otherwise seemingly proper for Class 436 when the compositions are colloid systems or wetting agents.
600, Surgery, for diagnostic methods which utilize light sensing units on or in the body for the testing or the inspection of blood and
368, for a method wherein a physical characteristic of blood is measured by means placed against or in the body, e.g., time required for blood to clot, sedimentation rate, white cell count or viscosity.
