How to perform the test in short
- Sampling: Collect the stool sample on the provided collection paper. Unscrew the test cup cap and poke the sampling stick into 3 different places in the sample.
- Preparation: Insert the stick back into the test cup with buffer, screw the cap tight, and shake for 10–15 seconds. Let the cup stand for 2 minutes. Peel off the plastic seal from the bottom of the cup, place it on a flat surface, and press down from the top to start the reaction.
- Reading: Keep the test upright and read the result at 5 minutes. (Do not interpret the result after 10 minutes have passed).
Result interpretation & Important advice
- Positive result (Two colored lines C and T): Occult (hidden) blood has been detected in the stool. Important: A positive result indicates gastrointestinal bleeding and should always be followed up by a doctor or healthcare center for further medical evaluation.
- Negative result (One colored line at C): No blood was detected in the stool sample. If you have persistent gastrointestinal symptoms, altered bowel habits, or abdominal pain, you should still consult a physician.
- Important limitations: Samples should not be collected during menstruation (or within 3 days before/after), if suffering from bleeding hemorrhoids, or if blood is present in urine. Avoid excessive intake of alcohol, aspirin, or anti-inflammatory drugs at least 48 hours prior to testing as they may cause gastrointestinal irritation. No dietary restrictions required.
