H.Pylori Antibody Rapid Test
For professional use only.
For in vitro diagnostic use only.
【INTENDED USE】
The H. pylori Antibody Rapid Test (Whole Blood/Serum/Plasma) is a rapid visual It is used to detect Helicobacter pylori antibody in human whole blood, serum or plasma samples.This kit is intended for use as an aid in the diagnosis of H. pylori infection.
【INTRODUCTION】
Gastritis and peptic ulcers are among the most common human diseases. Since the discovery of H. pylori (Warren & Marshall, 1983), many reports have suggested that this organism is one of the major causes of ulcer diseases (Anderson & Nielsen, 1983; Hunt & Mohamed, 1995; Lambert et al, 1995). Although the exact role of H. pylori is not yet fully understood, eradication of H. pylori has been associated with the elimination of ulcer diseases. The human serological responses to infection with H. pylori have been demonstrated (Varia & Holton, 1989; Evans et al, 1989). The detection of IgG antibodies specific to H. pylori has been shown to be an accurate method for detecting H. pylori infection in symptomatic patients. H. pylori may colonize some asymptomatic people. A serological test may be used either as an adjunct to endoscopy or as an alternative measure in symptomatic patients.
【PRINCIPLE】
The Helicobacter pylori antibody rapid test, using immunochromatography to detect Helicobacter pylori antibody.Fix Helicobacter pylori antigen on the test area of the membrane. During testing, the specimen reacts with H. pylori antigen conjugated to colored particles and precoated onto the sample pad of the test. The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane. If there are sufficient antibodies to Helicobacter pylori 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.
【MAIN CONTENTS】
• Rapid test cassette with desiccant
• Buffer
• Pipette
• Package insert
【PRECAUTIONS】
• For professional in vitro diagnostic use only.
• Do not use after the expiration date indicated on the package. Do not use the test if the foil pouch is damaged. Do not reuse tests.
• This kit contains products of animal origin. Certified knowledge of the origin and/or sanitary state of the animals does not completely guarantee the absence of transmissible pathogenic agents. It is therefore, recommended that these products be treated as potentially infectious, and handled by observing usual safety precautions (e.g., do not ingest or inhale).
• Avoid cross-contamination of specimens by using a new specimen collection container for each specimen obtained.
• Read the entire procedure carefully prior to testing.
• Do not eat, drink or smoke in the area where the specimens and kits are handled. Handle all specimens as if they contain infectious agents. Observe established precautions against microbiological hazards throughout the procedure and follow standard procedures for the proper disposal of specimens. Wear protective clothes, disposable gloves and eye protection when specimens are assayed.
• Humidity and temperature can adversely affect results.
• Used testing materials should be discarded according to local regulations.
【STORAGE AND STABILITY】
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
【SAMPLE COLLECTION】
• The H. pylori Antibody Rapid Test is intended for use with human whole blood, serum, or plasma specimens only.
• Only clear, non-hemolyzed specimens are recommended for use with this test. Serum or plasma should be separated assoon as possible to avoid hemolysis.
• Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8°C for up to 3 days. For long term storage, specimens should be kept below -20°C. Whole blood collected by venipuncture should be stored at 2-8°C if the test is to be run within 2 days of collection. Do not freeze whole blood specimens. Whole blood collected by fingerstick should be tested immediately.
• Containers containing anticoagulants such as EDTA, citrate, or heparin should be used for whole blood storage.
• Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.
• If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents. Icteric, lipemic, hemolysed, heat treated and contaminated specimens may cause erroneous results.
【DIRECTION OF USE】
Bring tests, specimens, buffer and/or controls to room temperature (15- 30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification. For best results the assay should be performed within one hour.
2. Testing
For Serum or Plasma
Transfer 2 drops of serum or plasma to the specimen well (S) with the provided disposable pipette, then start the timer.
For Whole Blood
Transfer 1 drop of whole blood to the specimen well (S) of the cassette with the provided disposable pipette, then add 1 drop of buffer and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the result area in the center of the device.
3. Wait for the colored band(s) to appear. The result should be read within 15 minutes. Do not interpret the result after 20 minutes.
【INTERPRETATION OF RESULTS】
POSITIVE:
The presence of two lines as control line (C) and test line (T) within the result window indicates a positive result.
NEGATIVE:
The presence of only control line (C) within the result window indicates a negative result.
INVALID:
If the control line (C) is not visible within the result window after performing the test, the result is considered invalid. Some causes of invalid results are because of not following the directions correctly or the test may have deteriorated beyond the expiration date. It is recommended that the specimen be re-tested using a new test.
