Recombinant syphilis antigen (17KDa, 15KDa, 47KDa) is immobilized in the lest line region of the device. AccuTest Syphilis Rapid Test is a special test kit designed to detect Syphilis (Treponema Pallidum- IgA, IgM, IgG) antibodies in serum/plasma. This kit is easy to use at home and gives you 99% accurate result in just 5 -20 minutes, with sensitivity and specificity of 99.67%. 1. AccuTest Syphilis is a chromatographic immunoassay kit for rapid qualitative detection of Treponemal antibodies (IgA, IgM, IgG) generated against Treponema pallidum Antigens (17KDa, 15KDa, 47KDa) in human serum or plasma with high sensitivity and specificity. 2. Results just in 5-20 minutes 3. Accu Test Syphilis exhibits sensitivity and specificity of 99.67%. Features: Based on Chromatographic Immunoassay assay for detection of Treponema pallidum antigens Sample: Human Serum or Plasma 2-3 drops of Serum/Plasma sample required for testing Fast: 1 step method, result in just 5 to 20 minutes Excellent sensitivity and specificity of 99.67% Store unused kit at 2-30C Pack size: 50 T Recombinant syphilis antigen (17KDa, 15KDa, 47KDa) is immobilized in the lest line region of the device. After the specimen is added to the specimen well in the device, it reacts with syphilis antigen coated particles in the test. The mixture migrates chromatographically along the length of the test strip and interacts with the immobilized syphilis antigen. The double antigen test format can detect IgA, IgG & IgM in specimens. If the specimen contains TP antibodies a coloured band will appear in the lest line region indicating a positive result. In the absence of TP antibodies a coloured band will not appear in the region indicating a negative result. To serve as a procedural control, a coloured band will always appear in the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred. Based on Chromatographic Immunoassay assay for detection of Treponema pallidum antigens Sample: Human Serum or Plasma 2-3 drops of Serum/Plasma sample required for testing Fast: 1 step method, result in just 5 to 20 minutes Excellent sensitivity and specificity of 99.67% Store unused kit at 2-30C Pack size: 50 T Direction for Use Procedure: 1. Bring the pouch to room temperature before opening to avoid condensation of moisture on the membrane of the device. Also bring the specimen to R.T. prior to testing. 2. Label the device with patient’s identification. 3. Add 2-3 drops (approx. 30 pl) of sample into the sample well of the test device. Avoid overflowing. 4. Wait for 5 – 20 minutes and read the result. It is important that the background is clear beforg the result is read. Note: Do not read the result after 30 minutes since specimen back flow may cause false result. STORAGE, STABILITY & HANDLING 1. The kit should be stored at 2 – 30° C. Do not freeze. 2. Do not use the kit past the expiration date stated on label. 3.

Buy Dengue NS1 Antigen test (Pack of 5 test) from Accurex. This NS1 Antigen Rapid test contains: A Test device in aluminum pouch with a desiccant, Disposable dropper & Pack Insert. Dengue NS1 antigen test utilizes the human serum / plasma followed by solid-phase immuno-chromatographic technology for the qualitative detection of dengue virus NS1 antigen. Dengue NS1 Antigen kit is for professional use and only for the initial screening test & reactive samples should be confirmed by a supplemental assay such as nucleic acid test & other immunological assays. EXPLANATION OF THE TEST Dengue NS1 antigen test utilizes the human serum / plasma followed by solid-phase immuno-chromatographic technology for the qualitative detection of dengue virus NS1 antigen. The membrane strip of the kit contains pre-coated anti-dengue NS1 monoclonal antibody on the test band region (T), and goat anti-mouse IgG is pre-coated on the control band region (C). During testing, if the sample containing dengue NS1 Ag, the complex of the antibody-dengueNS1 Ag-gold conjugate moves laterally on the membrane by capillary action. In this case, the colored band will appear on the membrane in test line (T). Control line (C) should always appear if the test procedure is performed properly Safety Information 1. For in-vitro diagnostic use only. Do not re-use the test device. 2. The instruction must be followed exactly to get accurate results. 3. Anyone performing an assay with this product must be trained in its use and must be experienced in laboratory procedures. 4. Do not eat or smoke while handling specimens. 5. Wear protective gloves while handling specimens. Wash hands thoroughly afterwards. 6. Avoid splashing or aerosol formation. 7. Clean up spills thoroughly using an appropriate disinfectant. 8. Decontaminate and dispose of all specimens, reaction waste, in a biohazard container. 9. Do not mix and interchange different specimen. 10. The presence of humidity may decrease the stability of the tests. Thus, carry out the test immediately after removing the device from the foil pouch. 11. Do not use it beyond the expiration date. Direction for Use 1. Place all specimens, test device and solution. Allow them to room temperature prior to testing (15~30 min.) 2. Please perform the test immediately after removing the device from the foil pouch. 3. With a disposable dropper, load 2-3 drops (50 to 75µl) of specimen into the sample well (S) in the test device. 4. Interpret the test results between 15~20 minutes.
