APPARATUS AND METHOD FOR DETERMINING SUBSTANCES CONTAINED IN A BODY FLUID

摘要

The invention describes methods for determining cholesterol in low density lipoproteins (LDL) in a living sample by reacting the sample with a reagent in the presence of an non-ionic surfactant and at least one member selected from the group consisting of cyclodextrin and derivatives thereof using novel techniques. An apparatus (10) for the optoelectric evaluation of test paper strips (12) for use in the methods for detection of certain analytes in blood or other body fluids is also provided. The figure shows a reflectance photometer (10) used to perform the methods of this invention and includes various features, including a lot number reader (66) wherein if the test strip (12) does not match the memory module (84), a test is not performed, and the user is instructed to insert a correct memory module (84).
