How
sensitive is the Clearview EASY HCG pregnancy test?
Clearview EASY HCG is
sensitive to 25 mIU/ml hCG in urine.
How
accurate is the Clearview EASY HCG pregnancy test?
Clearview EASY HCG 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
Clearview EASY HCG pregnancy 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 Clearview EASY HCG. Do not add
preservatives or use a container with preservative.
How
soon can the Clearview EASY HCG pregnancy test be
used?
Clearview EASY HCG 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 Clearview EASY
HCG 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 10 minutes.
The Test Line is very faint,
what does this mean?
Samples containing 5 – 25 mIU/ml hCG may
produce weak positive results. In such cases a repeat test is
recommended 48 to 72 hours later. However, provided the Control
Line is present a weak positive should be recorded as a valid
positive result.
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 EASY HCG pregnancy test be used to detect ectopic
pregnancy?
Clearview EASY HCG 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.
