Frequently Asked Questions
How
sensitive is the Clearview HCG pregnancy test?
The Clearview HCG pregnancy
test is sensitive to 25 mIU/ml hCG in urine.
How
accurate is the Clearview HCG pregnancy test?
The Clearview HCG pregnancy
test has been shown to be >99% accurate in clinical trials.
Can urine samples
be stored in the fridge / freezer?
Yes, they can be stored for up to 72 hours
between 2 - 8°C or up to 3 months if frozen at -20°C. However,
samples must always be brought to room temperature prior to
use.
Can the test be
used directly from the fridge?
No, although the kit can be stored at 2 -
30°C, it must be allowed to equilibrate at 18 - 30°C before
use.
Do urine
samples need to be collected in containers containing
preservatives?
No.The use of preservatives has not been
validated with the Clearview HCG pregnancy test.
Do not add preservatives or use a container with preservative.
How soon
can the Clearview HCG pregnancy test be used?
The Clearview HCG pregnancy
test 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 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 the Clearview
HCG pregnancy test with a urine 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?
The result should be read 3 minutes after
sample application, do not interpret results after 3
minutes.
The Test 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, 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 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 pregnancy test be used to detect ectopic
pregnancy?
The Clearview HCG pregnancy
test 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.
