30°C, it must be allowed to equilibrate at 15 - 30°C before
use.

to be collected in containers containing

No. The use of preservatives has not been
validated with Clearview hCG Combo. Do not add
preservatives or use a container with preservative.
How
soon can the Clearview hCG Combo pregnancy test be
used?
Clearview hCG Combo can
detect hCG in urine at concentrations ≥ 25 mIU/ml. On the
first day of the expected period the level of hCG in the urine and
serum of a pregnant woman is expected to range between 50 – 250
mIU/ml.
When is the best time of
day to test?
It is possible to use Clearview hCG
Combo with a urine or serum sample collected at any time
of day. However, a first morning urine sample will usually contain
the highest level of hCG.
How
critical is the timing and are the results
stable?
Read the result at 3 minutes when testing a
urine sample. Do not interpret the result after 3
minutes. Read the result at 5 minutes when testing a serum
sample. Do not interpret the result after 5 minutes.
The Result Line is very
faint, what does this mean?
A Test Line irrespective of it's intensity in
the presence of the Control Line should be interpreted as a
positive result. In such cases a repeat test is recommended 48 to
72 hours later.
Sometimes
the Test Line can be fainter or darker than the Control Line. How
should this result be interpreted?
The presence of the Test Line in the Result
Window indicates a positive result, regardless of its intensity
compared to the Control Line.
No Control Line has appeared
in the Result Window, 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 excessive sample to the test.
Will fertility
drugs affect the test result?
Fertility drugs containing hCG can give
misleading results. We recommend that a pregnancy test is not
carried out until at least 14 days have passed since the
administration of these drugs, testing too soon may give a false
positive result.
Do hormonal
contraceptives affect the test?
No. However if a woman has recently
discontinued the use of hormonal contraceptives her periods may not
be regular. In such cases we recommend testing 19 days after the
last unprotected sexual intercourse.
Can
the Clearview hCG Combo pregnancy test be used to detect ectopic
pregnancy?
Clearview hCG Combo can be a
useful aid in the diagnosis of ectopic pregnancy, although it
cannot distinguish ectopic pregnancies from normal pregnancies As
ectopic pregnancies may produce lower levels of hCG than those
found in normal pregnancies of a similar gestational time-point, it
is important that a sensitive hCG test is used.
If an ectopic pregnancy is suspected, it
should always be followed up with a suitable confirmatory
method.
