Intended use The one step dengue ns1 ag test is a rapid chromatographic immunoassay for the qualitative detection of dengue virus ns1 antigen in serum or plasma to aid in the diagnosis of dengue viral infection. Summary Dengue is transmitted by the bite of an aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3-14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults. Dengue haemorrhagic fever (fever, abdominal pain, vomiting, bleeding) is a potentially lethal complication, affecting mainly children. Early clinical diagnosis and careful clinical management by experienced physicians and nurses increase survival of patients. One step dengue ns1 ag test is a simple, visual qualitative test that detects dengue virus ns1 antigen in human serum or plasma. The test is based on immunochromatography and can give a result within 15 minutes.
Intended use The one step anti-dengue (igm & igg) tri-line test is a colloidal gold enhanced, rapid immunochromatographic assay for the qualitative detection of antibodies (igm & igg) to dengue virus (dv) in human whole blood, serum or plasma. This test is a screening test, and all positives must be confirmed using an alternate test such as western blot. The test is intended for healthcare professional use only.
INTENDED USE The HCG s/u Gold Rapid Screen Test(RST)is a chromatographic immunoassay for the early detection of human chronic gonadotropin (HCG) in serum/plasma or urine specimens. INTRODUCTION HCG is a glycoprotein hormone secreted by the developing placenta during pregnancy. The concentration of HCG in serum is approximately equal to the concentration in urine. The concentrations of HCG in urine and serum continue to rise during the first trimester of pregnancy to as high as 100,000 mIU/ml. HCG appears in urine shortly after conception, and continues to increase during the early stages of pregnancy, making it an excellent indicator for the detection of pregnancy. PRINCIPLE The membrane of the test device was coated with anti HCG antibodies on the test region and goat anti mouse IgG antibodies on the control region. During the test, urine specimen is allowed to react with the HCG monoclonal antibody-colloid gold conjugate, which was pre-dried on the test strip. The mixture then moves upward on the membrane chromatographically by capillary action. For a positive specimen, the conjugate binds to the HCG forming an antibody-antigen complex. This complex is captured by anti HCG antibody immobilized on the test region (T) and produces a pink color band when HCG concentration is equal to or greater than 25mIU/ml. Absence of this colored band in the test region suggests a negative result. To serve as a procedural control, a colored band at the control region(C) will always appear regardless the presence or absence of HCG. STORAGE The kits should be stored at temperature 4-30°C� the sealed pouch for the duration of the shelf life (24months).

Uncut Sheet Leishmania IgG/IgM Rapid Test Specimen:Whole Blood/ Serum/ Plasma INTENDED USE The Leishmania IgG/IgM Rapid Test is a lateral flow immunoassay for the qualitative detection of antibodies including IgG and IgM to the subspecies of the Leishmania donovani (L. donovani), the Visceral leishmaniasis causative protozoans in human serum or plasma. This test is intended to be used as a screening test and as an aid in the diagnosis of the disease of Visceral leishmaniasis. Any reactive specimen with the Leishmania IgG/IgM Rapid Test must be confirmed with alternative testing method(s). SUMMARY AND EXPLANATION OF THE TEST Visceral leishmaniasis, or Kala-azar, is a disseminated infection caused by several subspecies of the L. donovani. The disease is estimated by the World Health Organization (WHO) to affect approximately 12 million people in 88 countries1. It is transmitted to humans by bites of the Phlebotomus sandflies, which acquire infection from feeding on infected animals. Though it is a disease for poor countries, in Southern Europe, it has become the leading opportunistic infection in AIDS patients2-3. Identification of L. donovani organism from the blood, bone marrow, liver, lymph nodes or the spleen provides a definite means of diagnosis. However, these test methods are limited by the sampling method and the special instrument requirement. Serological detection of anti-L. donovani Ab is found to be an excellent marker for the infection of Visceral leishmaniasis. Tests used in clinic include: ELISA, fluorescent antibody and direct agglutination tests4-5. Recently, utilization of L. donovani specific protein in the test has improved the sensitivity and specificity dramatically6-7. The Leishmania IgG/IgM Rapid Test is a recombinant protein based serological test, which detects antibodies including IgG, IgM and IgA to the L. Donovani. This test provides a reliable result within 10 minutes without any instrumentation requirements.

Intended Use The Influenza A +B Test is a rapid chromatographic immunoassay for the qualitative detection of influenza type A and B nucleoprotein antigens in nasopharyngeal swab and nasal aspirate specimens. This kit is intended to be used as an aid in the diagnosis of influenza A and influenza B virus in nasal swab specimens. Principle The Influenza A +B Test is a qualitative membrane strip based immunoassay for the detection of influenza type A and B nucleoprotein antigens in nasopharyngeal swab and nasal aspirate specimens. In this test procedure, influenza type A antibody is immobilized in the A line, influenza type B antibody is immobilized in the B line. After a specimen is placed in the specimen well, it reacts with influenza type A antibody and/or B antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized antibody. If the specimen contains influenza type A, a colored line will appear in the A line region indicating a influenza type A positive result. If the specimen contains influenza type B, a colored line will appear in the B line region indicating a influenza type B positive result. Absence of any T lines (A and B) suggests a negative result. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred. Storage and Stability 1.Store as packaged in the sealed pouch at room temperature or refrigerated (4-30â?? or 40-86â??).

Specimen:Whole Blood /Serum / Plasma D-Dimer Rapid Test Device is used for the qualitative detection of D-dimer in human whole blood and plasma; The test is used as an aid in the assessment and evaluation of patients with suspected disseminated intravascular coagulation (DIC), deep vein thrombosis (DVT), and pulmonary embolism (PE). During blood coagulation process, fibrinogen is converted to fibrin by the activation of thrombin. The resulting fibrin monomers polymerise to form a soluble gel of non-cross-linked fibrin. This fibrin gel is then converted to cross-linked fibrin by thrombin activated Factor XIII to form an insoluble fibrin clot. Production of plasmin, the major clot-lysing enzyme, is triggered when a fibrin clot is formed. Although fibrinogen and fibrin are both cleaved by the fibrinolytic enzyme plasmin to yield degradation products, only degradation products from cross-linked fibrin contain D-dimer and are called cross-linked fibrin degradation products. Therefore, fibrin derivatives in human blood or plasma containing D-dimer are a specific marker of fibrinolysis. The D-Dimer Rapid Test Device (Whole blood//Plasma) detects D-Dimer through visual interpretation of color development in the internal strip. Anti-D-Dimer antibodies are immobilized on the test region of the membrane, and anti-mouse antibodies immobilized on the control region. During testing, the specimen reacts with anti-D-Dimer antibodies conjugated to colored particles and precoated onto the sample pad of the strip. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient D-Dimer in the specimen, a colored band will form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
One-Step Adenovirus Ag Rapid Test Formats:Uncut Sheets , Bulk Package, 30Tests/Box ,OEM Specimen:Feces INTENDED USE The Adenovirus Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative presumptive detection of adenovirus in human fecal specimens. This kit is intended to be used as an aid in the diagnosis of adenovirus infection. INTRODUCTION Acute diarrheal disease in young children is a major cause of morbidity worldwide and is a leading cause of mortality in developing countries. Research has shown that enteric adenoviruses, primarily Ad40 and Ad41, are a leading cause of diarrhea in many of these children, second only to the rotaviruses. These viral pathogens have been isolated throughout the world, and can cause diarrhea in children year round. Infections are most frequently seen in children less than two years of age, but have been found in patients of all ages. Further studies indicate that adenoviruses are associated with 4-15% of all hospitalized cases of viral gastroenteritis. Rapid and accurate diagnosis of gastroenteritis due to adenovirus is helpful in establishing the etiology of gastroenteritis and related patient management. Other diagnostic techniques such as electron microscopy (EM) and nucleic acid hybridization are expensive and labor-intensive. With the self-limiting nature of adenovirus infection, such expensive and labor-intensive tests may not be necessary.
The Chagas Ab Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of IgG anti-Trypanosoma cruzi (T. cruzi) in human serum or plasma. It is intended to be used as a screening test and as an aid in the diagnosis of infection with T. cruzi. Any reactive specimen with the Chagas Ab Rapid Test must be confirmed with alternative testing method(s) and clinical findings. Chagas disease is an insect-borne, zoonotic infection by the protozoan T. cruzi, which causes a systemic infection of humans with acute manifestations and long term sequelae. It is estimated that 16-18 million individuals are infected worldwide, and roughly 50,000 people die each year from chronic Chagas disease (World Health Organization)1. Buffy coat examination and xenodiagnosis used to be the most commonly methods2,3 in the diagnosis of acute T. cruzi infection. However, both methods are either time consuming or lack of sensitivity. Recently, serological test becomes the mainstay in the diagnosis of Chagasâ??s disease. In particularly, recombinant antigen based tests eliminate false-positive reactions which are commonly seen in the native antigen tests4-5. The Chagas Ab Rapid Test is an instant antibody test which detects IgG antibodies the T. cruzi within 15 minutes without any instrument requirements. By utilizing T. cruzi specific recombinant antigen, the test is highly sensitive and specific.
INTENDED USE The neisseria gonorrhoeae antigen test card is a rapid visual immunoassay for the qualitative detection of neisseria gonorrhoeae in female endocervical swab and male urethral swab specimens. This kit is intended for use as an aid in the diagnosis of neisseria gonorrhoeae infection. PRINCIPLE The neisseria gonorrhoeae antigen test kit is designed to detect N. Gonorrhoeae through visual interpretation of the color development in the internal strip. The membrane was immobilized with gonococcal Antigen-specific polychonal antibody on the test region (T) and related antibodies on the control region(C). During testing, the specimen is added to the sample region (S) and reacts with anti-gonococcus antibodies conjugated to colored particles and precoated onto the sample pad of the test. Then, the mixture migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient gonococcus antigens in the specimen, a colored band will form at the test region (T) of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
