The Transferrin Rapid Test (Feces) is a rapid chromatographic immunoassay for the qualitative detection of Human Transferrin in feces.
Many diseases can cause hidden blood in the feces. Transferrin, which is more resistant to the metabolism in the intestine than that of the Hemoglobin, provides the best complementary way of diagnosing the disease in the upper digestive tract. Transferrin is a blood plasma protein for iron ion delivery. Although iron bound to transferring is less than 0.1% (4 mg) of the total body iron, it is the most important iron pool with the highest rate of turnover (25 mg/24 h).
Transferrin imbalance can have serious health effects for those with high serum transferring levels. A patient with an increased serum transferring level suffers from iron deficiency anemia that is one of the most important symptoms when a tumor has caused chronic occult bleeding.
The Transferrin Rapid Test (Feces) is a rapid test to qualitatively detect low levels of Human Transferrin in feces. The test uses a double antibody sandwich assay to selectively detect Huma Transferrin at 4ng/ml or higher. In addition, unlike guaiac assays, the accuracy of the test is not affected by the diet of the patients.
• Rapid test cassette with desiccant.
• Specimen dilution tubes with buffer
• Package insert
• 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&Storage
• Specimens should not be collected during or within three days of a menstrual period, or if the patient suffers from bleeding hemorrhoids or blood in the urine.
• Alcohol, aspirin and other medications taken in excess may cause gastrointestinal irritation resulting in occult bleeding. Such substances should be discontinued at least 48 hours prior to testing.
• No dietary restrictions are necessary before using the Transferrin Rapid Test (Feces).
Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.
1. To collect fecal specimens:
Collect feces in a clean, dry specimen collection container. Best results will be obtained if the assay is performed within 6 hours after collection. Specimen collected may be stored for 3 days at 2-8ºC if not tested within 6 hours.
2. To process fecal specimens:
Unscrew the cap of the specimen collection tube, then randomly stab the specimen collection applicator into the fecal specimen in at least 3 different sites. Do not scoop the fecal specimen. Screw on and tighten the cap onto the specimen collection tube, then shake the specimen collection tube vigorously to mix the specimen and the extraction buffer. Specimens prepared in the specimen collection tube may be stored for 6 months at -20ºC if not tested within 1 hour after preparation.
3. Bring the pouch to room temperature before opening it. Remove the test cassette from the foil pouch and use it within one hour. Best results will be obtained if the test is performed immediately after opening the foil pouch.
4. Hold the specimen collection tube upright and open the cap onto the specimen collection tube.
Invert the specimen collection tube and transfer 2 full drops of the extracted specimen (approximately 80 µL) separately to the specimen well (S) of the test cassette, then start the timer. Avoid trapping air bubbles in the specimen well (S). See illustration below.
5. Read results at 5 minutes. Do not read results after 10 minutes.
