Abstract: A detection test assembly for detecting the presence of a substance preferably a blood substance in a feces sample comprising feces diluted in buffer solution or water is described. The blood substance is detected by acceptors having binding properties for the substance or that may be specifically bound by the substance. Said assembly comprises a reaction field having a mobile first acceptor with visualization properties and a detection field comprising a test field connected to and located downstream from the reaction field having an immobilized second acceptor. After direct application of a prepared feces sample to the assembly, first acceptor forms a complex with blood substance, flows to test field and binds to or is bound by immobilized second acceptor. Accumulation of first acceptor in the test field results in the formation of a visualizable line such as color different from the color of the test field itself. The detection test assembly includes at least two positive internal controls.

Abstract: The present invention provides a test device for determining the concentration of LDL-cholesterol in a sample. The test device has a continuous solid surface with at least one reaction area on the continuous solid surface, and the reaction area has, in dry form, a non-LDL inhibitor and a system for determining the concentration of cholesterol.

Abstract: The present invention provides a test device for determining the concentration of LDL cholesterol in a sample, comprising a solid surface with at least one reaction area, said at least one reaction area being provided with an Non-LDL inhibitor and a system for determining the concentration of cholesterol.

Abstract: A device for determining a substance contained in a body fluid is provided. An indicator member has a testing zone that changes the color based on the concentration level of the substance contained in a body fluid applied to the testing zone. The indicator member is rotatably mounted on a basic carrier. A set of differently colored color fields is provided on the basic carrier along the circumference of a circle having a radius from the center of said basic carrier. The indicator member rotates about the center of said basic carrier. The changed color of said testing zone of said indicator member is compared to said differently colored color fields on the basic carrier.

Abstract: A device for determining a substance contained in a body fluid is provided, wherein a testing zone coated with a testing substance capable of changing its color in dependence on the concentration of the substance to be determined is provided on an indicator member, the indicator member being rotatably arranged on a basic carrier, wherein differently colored color fields are provided on the basic carrier in accordance with a circle line extending about a center of rotation of the indicator member, corresponding concentration indications of the substance to be determined being associated to said differently colored color fields.
