FOBCHECK Rapid Home Screening Test


FOBCHECK is a rapid one-step test for the qualitative detection of human haemoglobin in faecal samples. FOBCHECK is designed to help diagnose gastrointestinal disorders and detects human haemoglobin (Hb) with a cut-off level of 40 ng/ml. In addition to possible intestinal diseases such as diverticulitis, colitis, or colon polyps, the blood in the stool sample may indicate an early stage of colorectal cancer. The final diagnosis must be confirmed and treated by a healthcare practitioner.

Hidden blood in the stool can be an indicator of various diseases such as diverticulitis, colitis, colon polyps or colorectal cancer. Screening for hidden blood can significantly reduce mortality from colorectal cancer. In the case of a positive test result, further investigation by a doctor is necessary for correct diagnosis and treatment.


  • Rapid screening for early detection.
  • Minimal sample contact.
  • Easy to use.
  • Detects human occult blood as low as 40 ng/ml haemoglobin as the threshold level.
  • No cross-reactivity to haemoglobin from other species.

Who should get tested?

Adults suspecting colorectal cancer, polyps or patients with other gastrointestinal diseases or a family history of gastrointestinal diseases. Symptoms could be, among others, lower abdominal pain, frequent diarrhoea, changes in stool appearance (e.g. black stool) and weight loss.

What should I do if I test positive?

Receiving a positive result can be difficult. Please make an appointment to see your doctor or local clinic in order to receive the appropriate treatment to ensure your optimal health.
