Product Description
The presence of fecal occult blood in the stool is associated with gastrointestinal disorders such as polyps, diverticulitis, and Crohn's disease, which may lead to colorectal cancer if not detected and treated early. Compared to the widely available Guaiac test, the One Step Fecal Occult Blood Test by Blue Cross is an immunochemical assay with much higher sensitivity and is designed to be more specific in detecting low levels of human fecal occult blood. It does not require special dietary restriction on patients. One Step Fecal Occult Blood Test is a rapid test that can be performed without the use of an instrument. Test yields a positive result when the concentration of hHb in test specimen is at or above 100ng/ml.
Storage&Stability:
The test kit can be stored at temperatures from 4°C to 30°c in the sealed pouch up to date ofexpiration.The test kit should be kept away from direct sunlight and moisture.Do not freeze the test kit.
Specimen Collection:
Blood should be collected aseptically into a clean tube without anticoagulants.Separate the serum or plasma from blood as soon as possible to avoid hemolysis.Use clear non-hemolyzed specimens when possible.
Format | Specimen | Size(mm) |
Strip | Whole Blood/Serum | 2.5,3.0 |
Cassette | Whole Blood/Serum | 3.0,4.0 |
Strip | Serum/Plasma | 2.5,3.0 |
Cassette | Serum/Plasma | 2.0,4.0 |
Test Procedure: |
1. Allow the test kit,specimen,and/or controls to equilibrate to room temperature(15-30°C) prior to testing. |
2. Remove the test kit from the foil pouch and use it as soon as possible.Best results will be obtained if the assay is performed within one hour. |
3. Place the test device on a clean and level surface.Transfer the specimen by a disposable specimen dropper(or a pipette):To use a hold the dropper vertically,draw the specimen up to the fill line as shown in illustration below(approximately 40uL). Transfer the specimen to the specimen well(S) of the test device and start the timer.Aviod trapping air bubbles in the specimen well (S). |
4. Wait for the red line(s) to appear.The result should be read at 15 minutes.Do not interpret the results after 20 minutes. |
Results: |
Positive: In addition to a pink colored control (C) band,a Distinct pink colored band will also appear in the test (T) region. |
*Note (Weak Positive): Colored band appearing in control Region (C) together with a faint colored band in Test Region (T). |
Negative:
Only one colored band appears on the control (C) region.No apparent band on the test (T) region. |
Invalid:
A total absence of color in both regions is an indication of procedure error and/or the test reagent has deteriorated. |
