Colon Cancer (FOB) Test

Concentrated levels of FOB will show as a positive test result on the test region (T) of the cassette and the more intense the colour, the higher the concentration of FOB in the sample which can indicate a gastrointestinal issue or disease.

The results can then be used to seek further medical advice and to implement healthier lifestyle choices depending on the body’s condition.

1

Receive your test kit in the post

2

Collect the sample using the stool catcher*

3

Unscrew the blue cap from the sample collection tube and randomly stab the sample with the sample
collection applicator in at least 3 different sites of the sample.

4

Replace the sample collection applicator into the tube, screw the cap tightly and shake the tube
vigorously to mix.

5

Remove the white cap from the buffer tube and squeeze 2 drops of extracted sample into the S well of
the test cassette.

6

Wait 5 minutes for the results to appear.

NOTE: Do not interpret before 5 minutes or after 10 minutes as the
results may be inaccurate.

The FOB rapid test detects low levels of FOB qualitatively and a double antibody sandwich assay is used. The test cassette membrane is precoated in an anti-Haemoglobin antibody covering the test line region (T) which the FOB in the specimen reacts with. The mixture migrates upwards by capillary action, reacting with the anti-Haemoglobin antibody and generating a coloured line.  Two coloured lines on the cassette in the C (Control) and T (test) regions indicate a positive result and a valid test result.

Blood in your stool means there is bleeding somewhere in your digestive tract. Sometimes very small amounts can only be detected by a Faecal Occult Test and sometimes it may visible on toilet tissue or in the toilet after a bowel movement. Bleeding that occurs in the higher digestive tract may make stool specimens appear black and tarry.

Persistently high concentrations of FOB can indicate early stages of gastrointestinal disease, however a diagnosis should not be based on the results of one single lateral flow test and further medical investigation should be sought.

All information in the reports produced is intended to support medical advice to optimise your health. The results cannot be used to diagnose, treat or cure medical/health conditions.

Always seek the advice of your doctor or another qualified health provider if you have a medical condition and/or medical symptoms. Never disregard professional medical advice or delay in seeking it.

Over half of your blood contains plasma, which is made of water, salts, and protein, in addition to red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs, including your gastrointestinal system.
Gastrointestinal bleeding (GI bleed) or gastrointestinal haemorrhage (GIB); means any form of bleeding in the gastrointestinal tract that locationally can be from the mouth to the rectum.

There are two main types of gastrointestinal bleeding: upper gastrointestinal bleeding and lower gastrointestinal bleeding. The diagnosis can begin with small amounts of bleeding detected in the faecal occult blood test, followed up with physical examinations, medical history and further medical investigations to locate the area of bleeding, endoscopy or medical imaging tools.

Small amounts of bleeding over a long period of time may cause iron-deficiency anaemia resulting in general fatigue or mild chest pain. Other symptoms may include abdominal pain, shortness of breath, pale skin, dizziness, or fainting. In some cases, there are no symptoms and persistent small bleeds go undetected.

Significant gastrointestinal blood loss over a short time may include symptoms such as vomiting blood, bloody stool, or black tarry stool.

The causes of upper GI bleeds can include peptic ulcer disease, oesophageal varices related to liver cirrhosis and cancer, among other diseases. The causes of lower GI bleeds may include haemorrhoids, colon cancer, and a variety inflammatory bowel disease. Early detection can improve health conditions and my prevent serious gastrointestinal damage.
