Can
I use Clearview Simplify D-dimer as a stand alone
test?
Clinical diagnosis must not be based on the
result of the Clearview Simplify D-dimer test
alone. The full clinical context of the patient should be
included when making a diagnostic decision, taking into account the
clinical signs and other relevant information such as the Wells
pre-test probability score or equivalent.
Can I report a
positive result before 10 minutes?
Only a positive result may be reported before
the 10 minutes providing that the procedural control line is
present. However a negative result cannot be reported before
10 minutes.
No Control line appeared what does
this mean?
The test has not run correctly. This may
occur if the pouch has been opened for too long prior to the test
being carried out. It could also be a consequence of adding
insufficient or excess sample/buffer to the test. The test
result is void and must be repeated.
The Test line
is fainter than the control line, is this a positive
result?
Yes. The appearance of a line in the
test zone (T) regardless of its intensity must, in the presence of
a Control line, be recorded as a positive result.
