Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
71 words
A diagnostic kit for detecting LDL cholesterol in a body fluid containing LDL cholesterol and another form of cholesterol selected from VLDL cholesterol, HDL cholesterol, and combinations thereof comprising, in combination: a. a reagent containing a lectin which is a specific agglutinating agent for LDL whereby LDL contained in said body fluid can be selectively agglutinated; and, b. a reagent for determining the amount of cholesterol in said specifically agglutinated LDL.
Claim 2
Dependent Claim
