The OnSite Troponin I Combo Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of cardiac Troponin I (cTnI) in human serum, plasma or whole blood at a level equal to or higher than 1 ng/mL. It can be performed within 15 minutes by minimally skilled personnel, and without the use of laboratory equipment. The OnSite Troponin I Combo Rapid Test is intended to be used by healthcare professionals as an aid in the diagnosis of acute myocardial infarction (AMI). Any use or interpretation of this preliminary test result must also rely on patient’s symptoms and the professional judgment of a physician. A more precise test method such as an instrument method must be used to confirm the test result obtained by this device. Normally the level of cTnI in the blood is very low. cTnI is released into the blood stream in forms of free cTnI and cTnI-C-T complex at 4-6 hours after myocardial cell damage. The elevated level of cTnI could be as high as 50 ng/mL during 60-80 hours after AMI and remains detectable for up to 10-14 days post AMI. Therefore, circulating cTnI is a specific and sensitive marker for AMI.

The new and improved RTR-1 uses an image processing method. During measurement, the lateral flow device is captured using a 5-mega pixel camera and the picture is analyzed using image processing algorithms for identification of either presence or absence of test line bands or test line band intensity levels. The reader converts the image into a grayscale and then classifies the intensity levels of the image in 0 to 255 grayscale range. The image processing algorithm undergoes various levels of filtering and segmentation to yield the correct intensity levels from the picture. Based on the preconfigured intensity levels, the reader classifies the band intensity and reads out the results as either positive or negative.

Buy AccuTest Typhoid IgG/IgM Rapid Card Test (5 Tests) Online from Accurex. The Typhoid IgG/IgM Rapid Test is used for detection & differentiation of anti-Salmonella typhi (S. typhi) IgG and IgM in human whole blood / serum / plasma. This Typhoid test is used as a screening test and as an aid in the diagnosis of infection with S. typhi. Salmonella typhi bacteria causes typhoid Typhoid fever, typhoid symptoms symptoms are likely to develop gradually – appearing one to three weeks after exposure to the disease. There are various typhoid treatment & typhoid vaccine which can be opted after the detetction of Typhoid. Typhoid fever is caused by S. typhi, a Gram-negative bacterium. Worldwide an estimated 17 million cases and 600,000 associated deaths occur annually. Patients who are infected with HIV are at significantly increased risk of clinical infection with S. typhi. Evidence of H. pylori infection also presents an increased risk of acquiring typhoid fever. 1-5% of patients become chronic carrier harboring S. typhi in the gall bladder. The clinical diagnosis of typhoid fever depends on the isolation of S. typhi from blood, bone marrow or a specific anatomic lesion. In the facilities that can not afford to perform this complicated and time-consuming procedure, Filix-Widal test is used to facilitate the diagnosis. However, many limitations lead to difficulties in the interpretation of the Widal test. In contrast, the Typhoid IgG/IgM Rapid Test is a simple and rapid laboratory test. The test simultaneously detects and differentiates the IgG and the IgM antibodies to S. typhi specific antigen thus to aid in the determination of current or previous exposure to the S. typhi. PRINCIPLE The Typhoid IgG/IgM Rapid Test is a lateral flow immunochromatographic assay. The test cassette consists of: 1) a pink-purple colored conjugate pad containing recombinant S. typhi H antigen and O antigen conjugated with colloid gold (Typhoid conjugates) and rabbit IgG-gold conjugates, 2) a nitrocellulose membrane strip containing two test region (Test line M and G) and a control region (control line). The test line ‘M’ is pre-coated with monoclonal anti-human IgM for the detection of IgM anti-S. typhi, test line ‘G’ is pre-coated with monoclonal anti-human IgG for the detection of IgG anti-S. typhi , and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is dispensed into the sample well of the cassette, the test specimen migrates by capillary action across the test cassette. Anti-S. typhi IgM if present in the patient specimen will bind to the Typhoid conjugates. The immunocomplex is then captured on the membrane by the pre-coated anti-human IgM antibody at test region ‘M’, forming a pink-purple line at ‘M’ region, indicating a S. typhi IgM positive test result. Anti-S. typhi IgG if present in the patient specimen will bind to the Typhoid conjugates. The immunocomplex is then captured by the pre-coated reagents on the membrane, forming a pink-purple line at test region ‘G’, indicating a S. typhi IgG positive test result. Absence of any pink-purple line at test region (M and G) suggests a negative result. The test contains an internal control (control line) which should exhibit a pink-purple line of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the test region. Otherwise, the test result is invalid and the specimen must be retested with another device. PRECAUTION 1. This package insert must be read completely before performing the test. Failure to follow the insert gives inaccurate test results. 2. Do not open the sealed pouch, unless ready to conduct the assay. 3. Do not use expired devices. 4.
