Clearview FOB
The Clearview
FOB test is a rapid, one-step test for the qualitative
detection of human occult blood in faeces.
Many diseases can cause hidden blood in the
faeces. This is also known as Faecal Occult Blood (FOB), human
occult blood or human haemoglobin. In the early stages,
gastrointestinal problems such as colon cancer, ulcers, polyps,
colitis, diverticulitis, and fissures may not show any visible
symptoms, only occult blood. The traditional testing methods which
are Guaiac-based methods, lack sensitivity and specificity and also
have diet restrictions prior to testing.
FOB testing primarily functions as a screening
method for early colorectal cancer. The Clearview
FOB test is designed to detect human haemoglobin in
faeces. The reason for this approach is that large adenomas and
most cancers bleed intermittently in the Gastro Intestinal (GI)
tract. The ability to detect resultant blood in faeces may be the
only symptom enabling early diagnosis of a potential cancer.
Additionally, removing bleeding polyps while still localised within
the GI wall can stop them developing into cancers at a later
stage
The Clearview
FOB test is a simple and rapid diagnostic test offering
fast results and excellent sensitivity. The advanced technology of
the Clearview FOB test gives healthcare
practitioners extra confidence in its accuracy. The in-built
procedural control indicates that the Clearview
FOB test has been performed correctly.

How to use the
Clearview FOB test
Step 1
Collect faecal specimen in a
clean, dry specimen collection container (F). To process the faecal
specimen unscrew the cap of the specimen collection tube, then
randomly stab the specimen collection stick into the faecal
specimen in at least 3 different sites (A). Screw on and tighten
the cap onto the specimen collection tube,then shake the specimen
collection tube vigorously to mix the specimen and the extraction
buffer.
Step 2
Hold the specimen collection tube upright and break off the tip of
the specimen collection tube (B). Invert the specimen collection
tube and transfer 2 full drops of the extracted specimen
(approx. 90 µL) to the
specimen well (S) of the test device, then start the timer.
Step 3
Wait for the coloured line/lines to appear. Read
results at 5 minutes.
