Clearview iFOB
The Clearview
iFOB test is a immunochemical 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
iFOB 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
iFOB test is a simple and rapid diagnostic test offering
fast results and excellent sensitivity. The advanced technology of
the Clearview iFOB test gives healthcare
practitioners extra confidence in its accuracy. The in-built
procedural control indicates that the Clearview
iFOB test has been performed correctly.

How to use the
Clearview iFOB test
Step 1 - To collect fecal specimens:
Collect feces in a clean, dry specimen collection container (F)
or a specimen collection sheet (G). Best results will be obtained
if the
assay is performed within 6 hours of collection. Specimens may
be stored for 3 days at 2-8°C if not tested within 6 hours.
Step 2 - To
transfer fecal specimens into the collection tube with the
extraction buffer:
Unscrew the blue cap of the specimen collection tube
(A), then randomly stab the specimen collection
stick into the fecal specimen in at least 3 different sites
(B). Do not scoop the fecal specimen.
Screw the blue cap back onto the specimen collection tube tightly,
then shake the specimen collection tube vigorously to
mix the specimen and the extraction buffer. Specimens
prepared inthe specimen collection tube may be stored for 3 days at
room temperature (15-30°C) if not tested within 1 hour of
preparation.

Step 3 - Test Performance:
When ready to perform the test remove the test device from the
sealed pouch and place on a clean and level surface. Do not touch
the membrane of the strip.
Stage 4
Invert and hold the specimen collection tube upright and
unscrew the red cap of the specimen collection tube (D).
Invert the specimen collection tube and transfer 2
full drops of the extracted specimen (approx. 100 μL) to the
specimen well (S) of the test device, then start the
timer. See illustration. Avoid trapping air bubbles in the specimen
well (S).
Stage 5
Wait for the colored line(s) to appear. Read
results at 5 minutes.
