Clearview C. Diff A is a one-step test for the direct
qualitative detection of Clostridium difficile toxin A
from fecal samples.
Clearly Different
Clearview C. Diff A uses a patented, innovative technology to
provide fast, accurate detection of toxin A associated with
diarrhea.
- Fast: test provides results in just
30 minutes
- Easy: simple, single-step
procedure
- Reliable: built-in-control ensures
accuracy
- Flexible: test is suitable for both
single and batch testing
Clearly Better
Early detection with Clearview C. Diff A results in improved
efficiencies and better patient care.
- Enables timely and appropriate treatment with antibiotics
- Prevents further spread of C. difficile-associated
disease
Clearview® C. Diff A Testing Procedure
Prepare sample using the Clearview Stool
Filtration System or a benchtop centrifuge for 10 minutes at 13,500
rpm.
Add 6 drops/125 µL of filtrate to the sample
window.
Interpret the results after 30 minutes. A blue
line in the result window indicates a positive result and a blue
line in the control window shows that the test has been performed
correctly.
For full instructions for use, see package insert.
About C.
difficile
Clostridium difficile is a gram-positive, spore-forming
anaerobic bacterium. C. difficile is the leading cause of
diarrhea outbreaks or C. difficile-associated disease
(CDAD) in hospitals, infirmaries, and elderly care units. CDAD is
usually caused by antibiotic or chemotherapy disturbing the normal
balance of the gut flora.1 Virtually any antibiotic is
capable of causing the condition and studies have shown reduced
antibiotic prescription levels can significantly reduce CDAD
cases.2 Outbreaks in nosocomial environments are
difficult to control since the bacteria produces spores that are
difficult to eradicate.2
C. difficile has been identified as the organism
responsible for toxin production.3 C. difficile produces
two large molecular weight toxins, designated A and B. Toxin A is
considered to play a more important role in the etiology of
CDAD.4 The toxins produce symptoms in CDAD patients,
which can range from mild diarrhea to pseudomembranous colitis
(PMC). PMC manifests as adherent yellowish-white plaques on the
intestinal mucosa. Rapid diagnosis of C. difficile is
therefore important in order to treat patients and prevent spread
of the disease.2
