As for Urine Reagent Analysis Strip Uncut Sheets , we have various parameters ranging from 1 to 12 . We can provide you strip and uncut sheet URS format with high quality and competitive price PRINCIPLE AND EXPECTED VALUES URS Ascorbic acid: This test involves decolorization of Tillmannâ??s reagent. The presence of ascorbic acid causes the color of the test field to change from blue-green to orange. Glucose: This test is based on the enzymatic reaction that occurs between glucose oxidase, peroxidase and chromogen. Glucose if first oxidized to produce gluconic acid and hydrogen peroxide in the presence of glucose oxidase. The hydrogen peroxide reacts with potassium iodide chromogen in the presence of peroxidase. The extent to which the chromogen is oxidized determines the color which is produced, ranging from green to brown. Low amounts of glucose are normally excreted in urine.3 Glucose concentrations as low as 100 mg/dL, read at either 10 or 30 seconds, may be considered abnormal if results are consistent. At 10 seconds, results should be interpreted qualitatively. For semi-quantitative results, read at 30 seconds only. URS Bilirubin: This test is based on azo-coupling reaction of bilirubin with diazotized dichloroaniline in a strongly acidic medium. Varying bilirubin levels will produce a pinkish-tan color proportional to its concentration in urine. In normal urine, no bilirubin is detectable by even the most sensitive methods. Even trace amounts of bilirubin require further investigation. Atypical results (colors different from the negative or positive color blocks shown on the color chart) may indicate that bilirubin-derived bile pigments are present in the urine specimen, and are possibly masking the bilirubin reaction.
Syphilis Test INTRODUCTION Anti-Syphilis Test is a rapid direct binding test for the visual detection of anti-syphilis antibodies in serum as an aid in the diagnosis of syphilis infection. Test results are read visually without any instrument. It is based on the principle of double antigen sandwich immunoassay for determination of syphilis antibodies in serum. Purified recombinant syphilis antigens are employed to identify anti-Syphilis antibodies specifically. This one step test is very sensitive and only takes about 10 to 20 minutes. Syphilis Test SPECIMEN COLLECTION For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the serum from the clot. Use the serum for testing. If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen repeatedly. Syphilis Test PROCEDURE Strip 1.When you are ready to begin testing, open the sealed pouch by tearing along the notch. Remove the test from the pouch. 2. Immerse the strip into the container with the arrow end pointing towards the container. Do not immerse past the MAX (maximum) line. Take the strip out after 8-10 seconds and lay the strip flat on a clean, dry, onabsorbent surface (e.g., mouth of the serum container). 3.Wait 10-15 minutes and read result. Do not read results after 20 minutes. Cassette 1. Open a pouch containing a cassette, lay the cassette. 2. Using the plastic pipettor provided, draw about 2-3 drops (100mL) the sample into the sample well of the cassette. 3. Read results within 10-15 minutes. Do not read results after 20 minutes. INTERPRETATION OF RESULTS Negative: Only one pink band appears on test region of the Cassette. This indicates that there is no detectable Anti-Syphilis in the serum. Positive: Two pink bands appear on test region of the Cassette. This indicates that the specimen contains detectable amount of Anti-Syphilis. Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device. Syphilis Test PRECAUTION: 1.�Must use fresh specimen and avoid repetitive freezing, the result will be invalid 2.�Use it before expiry date. 3.The package of kit should not be opened until it reaches the room temperature if it taken out from the refrigerator. 4�.Old Serum can not be used. If the serum is thick, it can be used only after being separated. Syphilis Test LIMITATIONS The test is for in-vitro diagnostic use only.
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.
INTENDED USE The One Step RV IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Rubella (Virus) in Whole Blood /Serum / Plasma to aid in the diagnosis of RV infection. The test is based on immunochromatography and can give a result within 15 minutes. PRINCIPLE The One Step RV IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of RV antibodies (IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing RV recombinant envelope antigens conjugated with Colloid gold (RV conjugates) and rabbit IgG-gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with the antibody for the detection of IgM anti-RV, T2 band is coated with antibody for the detection of IgG anti-RV, 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 test cassette, the specimen migrates by capillary action across the cassette. IgG anti-RV, if present in the specimen, will bind to the RV conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a RV IgG positive test result and suggesting a recent or repeat infection. IgM anti-RV if present in the specimen will bind to the RV conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a RV IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device. Storage and Stability Store as packaged in the sealed pouch at room temperature or refrigerated (4-30â?? or 40-86â??). The test device is stable through the expiration date printed on the sealed pouch. The test must remain in the sealed pouch until use.
COVID-19 IgG IgM and Influenza A&B antigen Sealing Tube Test Strip Colloidal Gold INTENDED USE Amazing COVID-19 Ag/Ab IgG/IgM and Influenza Ag AB Sealing Tube Twin Test Strip is a lateral flow immunochromatographic assay for the simultaneous rapid in vitro differential detection of COVID-19 and Influenza virus. The kit has two strips. One is for the qualitative detection of COVID-19 nucleocapsid protein antigen and Influenza virus type A in human nasopharyngeal, nasal secretion, saliva or and serum directly collected from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset. Another is for the qualitative detection of COVID-19 antibody IgG/IgM in human serum, plasma sodium citrate, sodium heparin, dipotassium EDTA and whole blood sodium citrate, sodium heparin, dipotassium EDTA or fingerstick whole blood and Influenza virus type B in human nasopharyngeal, nasal secretion, saliva or/and serum specimens to aid identifying individuals with an adaptive immune response to COVID-19, indicating recent or prior infection and patients with suspected COVID-19 infection in conjunction with clinical presentation and the results of other laboratory tests. PRINCIPLE There are two test strips in the Amazing COVID-19 Antigen IgG IgM Filmseal Tube Twin Test. COVID-19 antigen test strip is based on sandwich lateral flow immunochromatographic assay highly sensitively detecting COVID-19 nucleocapsid protein in human nasopharyngeal, nasal secretion, saliva or and serum specimens, having an invisible T test zone and C control zone. When the sample is applied into the test tube, the liquid will laterally flow on the surface of the test strip. If there is enough COVID-19 antigen in the sample, a visible T band will appear. COVID-19 IgGIgM test strip is based on lateral flow immunochromatographic assay highly sensitively detecting COVID-19 IgG and IgM in human whole blood, serum, or plasma specimens, having an invisible IgGT1 zone, IgMT2 zone, and C control zone. When the sample is applied into the test tube, the liquid will laterally flow on the surface of the test strip. If there is enough COVID-19 IgG or and IgM in the sample, a visible IgGT1 or and IgMT2 band will appear in the corresponding area. The C band of two strips should always appear after a sample is applied, indicating a valid result. By this means, the kit can accurately indicate the presence of COVID-19 antigen, IgG, and IgM in the sample.
