The Wampole PreVue™ Borrelia burgdorferi Antibody Detection Assay is a single use, unitized immunochromatographic test that uses recombinant B. burgdorferi antigens for the qualitative presumptive (first step) detection of IgG and IgM antibodies to B. burgdorferi in human serum or whole blood. This test should be used only in patients with history, signs and symptoms that are consistent with Lyme disease. The Wampole PreVue™ Borrelia burgdorferi Antibody Detection Assay is intended for use in clinical and physicians' office laboratories.

The Wampole PreVue™ Borrelia burgdorferi Antibody Detection Assay is a Class II in vitro diagnostic device that utilizes standard immunochromatographic chromophore technology to qualitatively detect, in serum or whole blood, the presence of IgG and IgM antibodies to recombinant Borrelia burgdorferi antigens, as an aid in the diagnosis of Lyme Disease. It consists of a plastic housing, containing an absorbent material that collects the specimen and, with the addition of buffer, delivers it and adjacent adsorbed reagents, onto a chromatographic strip, onto which recombinant test antigen and control antibodies have been adsorbed within their respective test and control detection zones. As the mixture migrates along the strip, gold-conjugated antibodies specific for human IgG and IgM bind to the antibodies in the specimen. Antibodies specific for Borrelia burgdorferi antigens, if present, will bind to the adsorbed recombinant antigens in the test zone, resulting in a visually detectable colored line due to the presence of goldconjugated antibodies, which are bound to the specimen antibodies. If no antibodies to Borrelia burgdorferi are present, no line will appear in the test zone. A line will always appear in the control zone, indicating a valid result, as goat anti-human IgG antibodies adsorbed in the control zone bind excess IgG in the specimen, which have been bound to the gold-conjugate.

An OTC hCG Pregnancy Test for home use intended for the early detection of pregnancy. It is intended to measure hCG, a placental hormone, in urine sample.

The Sure Check™ Pregnancy Test is a self contained immunochromatographic test designed for use in detecting hCG in urine samples. After the person wets the wick in the device the urine is absorbed and transferred to a pad where a labelled colloidal gold containing a monoclonal antibody directed against beta hCG is present. If the antigen (hCG) is present, an antigen/antibody reaction takes place forming a complex. This migrates along the nitrocellulose support to the Test Line which is printed on the membrane. This is another antibody, in this case a monoclonal anti-hCG antibody, which captures the colored complex when it passes over the immobilized test line antibody. As the complex adheres to the capture antibody a visible light to dark purple band appears indicating a positive test result. The remaining complex travels further along the membrane to another immobilized control antibody. This captures the remaining complex forming another purple band indicating that the test has been performed properly.
