Liquid or liquid samples, or fluid samples, may be derived from solid or semi-solid samples, including fecal, biological tissue and food samples. The solid or semi-solid sample may be converted to a liquid sample by any suitable method, such as mixing, triturating, macerating, incubating, dissolving, or enzymatically digesting a solid sample in a suitable solution (e.g., water, phosphate solution, or other buffered solution). "biological samples" include samples derived from animals, plants and food, including, for example, urine, saliva, blood and components thereof, spinal fluid, vaginal secretions, sperm, feces, sweat, secretions, tissues, organs, tumors, cultures, cell cultures and media of tissues and organs derived from humans or animals. Preferably, the biological sample is urine and preferably, the biological sample is saliva. Food samples include food processing materials, end products, meat, cheese, wine, milk and drinking water. Plant samples include those derived from any plant, plant tissue, plant cell culture and medium. An "environmental sample" is derived from the environment (e.g., a liquid sample from a lake or other body of water, a sewage sample, a soil sample, groundwater, seawater, and a waste liquid sample). Environmental samples may also include sewage or other wastewater.

Test element

The term "test element" as used herein refers to an element that can detect whether a sample or specimen contains an analyte of interest, and the detection can be based on any technical principles, such as immunology, chemistry, electricity, optics, molecular, nucleic acid, physics, etc. The test element may be a lateral flow test strip which detects a plurality of analytes. Of course, other suitable test elements may be used with the present invention.

Various test elements may be combined and used in the present invention. One form is a test strip. Test strips for the analysis of analytes, such as drugs or metabolites indicative of a physical condition, in a sample may be in various forms, such as immunoassay or chemical assay forms. The test strip may be used in a non-competitive or competitive assay format. The test strip generally comprises a bibulous material having a sample application area, a reagent area, and a test area. The sample is added to the sample application zone and flows by capillary action to the reagent zone. In the reagent zone, the sample binds to the reagent if the analyte is present. The sample then continues to flow to the detection zone. Other reagents, such as molecules that specifically bind to the analyte, are immobilized at the detection zone. These reagents react with the analyte (if present) in the sample and bind the analyte to the zone, or to one of the reagents of the reagent zone. The label for indicating the detection signal is present in the reagent zone or in a separate label zone.

A typical non-competitive assay format is one in which a signal is generated if the sample contains the analyte and no signal is generated if the analyte is not present. In a competition method, a signal is generated if the analyte is not present in the sample and no signal is generated if the analyte is present.

The test element can be a test paper, and can be made of water-absorbing or non-water-absorbing materials. The test strip may include a variety of materials for liquid sample delivery. One of the test strips may be coated with another material, such as a nitrocellulose membrane coated with filter paper. One region of the test strip may be selected from one or more materials and another region may be selected from a different one or more materials. The test strip may be adhered to some support or hard surface for improved strength when the test strip is held in place.

The analyte is detected by a signal producing system, such as one or more enzymes that specifically react with the analyte, and one or more compositions of the signal producing system are immobilized on the analyte detection zone of the test strip by a method such as that described above for the immobilization of a specific binding substance on the test strip. The signal-producing substance can be on the sample addition zone, reagent zone, or detection zone, or the entire test strip, and the substance can be impregnated on one or more materials of the test strip. A solution containing the signal is applied to the surface of the strip or one or more materials of the strip are immersed in the solution containing the signal. The strip to which the solution containing the signal substance was added was dried.

The various regions of the test strip may be arranged as follows: the device comprises a sample adding area, a reagent area, a detection area, a control area, a sample adulteration area and a liquid sample absorption area. The control zone is located behind the detection zone. All zones may be arranged on a strip of test paper using only one material. It is also possible to use different materials for the different zones. The zones may be in direct contact with the liquid sample, or different zones may be arranged according to the direction of flow of the liquid sample, with the ends of each zone being contiguous with and overlapping the ends of the other zone. The material used can be a material with good water absorption such as filter paper, glass fiber or nitrocellulose membrane. The test strip may take other forms.

A commonly used reagent strip is a nitrocellulose membrane reagent strip, i.e., a detection area comprises a nitrocellulose membrane, and a specific binding molecule is fixed on the nitrocellulose membrane to display the detection result; and may be a cellulose acetate film, a nylon film, or the like. Such as the reagent strips or devices containing the reagent strips described in some of the following patents: US 4857453; US 5073484; US 5119831; US 5185127; US 5275785; US 5416000; US 5504013; US 5602040; US 5622871; US 5654162; US 5656503; US 5686315; US 5766961; US 5770460; US 5916815; US 5976895; US 6248598; US 6140136; US 6187269; US 6187598; US 6228660; US 6235241; US 6306642; US 6352862; US 6372515; US 6379620; and US 6403383.
