1. A method of estimating fat concentration in a waste fluid sample, the method comprising:

  • inducing cytolysis in the waste fluid sample producing a cytolytic fluid;

    variably scattering at a least a portion of light from a light source;

    intercepting the variably scattered light at two comparison chambers where one comparison chamber receives and transmits the cytolytic fluid and a second comparison chamber receives and transmits a reference standard fluid;

    detecting output light emanating from the two comparision chambers;

    comparing light absorption characteristics of the cytolytic fluid with light absorption characteristics of the reference standard fluid; and

    looking up in a table a fat concentration of a reference standard fluid having light absorption characteristics substantially similar to the cytolytic fluid.
