BOWEL-FOB TEST is an immunochromatographic device that detects the smallest amounts (above 40 ng/mL) of occult blood in stool samples.
| Specificity | 99% |
| Sensitivity | 78.7% |
| Accuracy | 92.6% |
CONTENT
- 1 test cassette
- 1 vial with collection stick and dropper containing the diluent
- 1 paper sheet for the collection of the sample
- instructions for us
USE PROCEDURE
- Collect the sample using the special collection sheet;
- Unscrew the cap of the vial, plunge the withdrawal stick in 3 different points of the sample and screw the cap back on;
- Break the end of the cap, freeing the dropper part, and dispense 3 drops of the diluted sample into the well (S) indicated on the cassette;
- Wait 5 minutes before reading the result.
RESULTS INTERPRETATION
| Negative | the presence of occult blood in the feces has not been detected or its concentration is below the reference cut-off. |
| Positive | the presence of occult blood in the feces has been identified. Positive results can also be obtained in the presence of hemoglobin concentrations between 40 ng/mL and 36 ng/mL. It is recommendable to further check with your doctor. |
