One step Ovulation Test
Instructions
TEST
DESCRIPTION
One
Step LH Urine Ovulation Test is fast and easy-to-use. It is a qualitative test
that predicts LH (Luteinizing Hormone) surge, and in turn, when you are likely
to ovulate and conceive. Females who are trying to become pregnant may use this
information to improve their chances of conception. Luteinizing Hormone is a
hormone released by the pituitary gland, a small gland at the base of the brain.
The hormone stimulates the ovaries to produce and release eggs each month during
the menstrual cycle. The level of LH in the blood and urine is highest before
ovulation. This increase in hormone level is sometimes called a
"surge". If fertility drugs are given to stimulate ovulation, an LH
test can help determine the best time for sexual intercourse. The LH test may
also be used to determine when eggs are mature enough to be surgically removed
from the ovary as part of the in vitro fertilization process. LH tests may also
aid in the diagnoses of polycystic ovary disease, premature ovarian failure, and
menopause. The
tests detect LH in urine in a qualitative format with sensitivity of 25mIU/mL
(International Standard Value) and specificity is 99.8%. Tests have an expiry
date of 2 years and can be stored in a dry environment ranging from 2 to 30
degrees Celsius. Results are available in just minutes.
WHEN
TO BEGIN TESTING
First,
you must determine the length of your menstrual cycle. This is the number of
days from the first day of your menstrual bleeding to the day before your next
bleeding begins again. Please refer to the chart
to determine when you should start testing. If your cycle is shorter than
21 days or longer than 38 days, consult your doctor. If you do not know your
cycle length, you may begin the test 11 days after your first period since the
average cycle length is 28 days. Perform 1 test each day over a 5 day period or
until the LH surge
has been detected.
URINE
COLLECTION
Do not use first morning urine samples as LH is synthesized in your body early
in the morning. It will not show up in your urine until later in the day.
The best time to collect your urine is between 10am - 8pm.
Collect urine at about the same time each day.
Reduce liquid intake about 2 hours before collecting your urine as a
diluted urine sample can prevent the test from detecting LH surge.Please refer
to the table below for information on when to start using ovulation tests:
TEST
PROCEDURE:
STEP
1
Collect urine in a clean container (such as plastic cup). The best way to
collect sample is by placing a cup in the middle of urination process.
STEP
2
Immerse the strip into the urine with the arrow end pointing towards the urine.
Do not immerse past the "Mark" line. Take the strip out after 5
seconds and lay the strip flat on a clean, dry, non-absorbent surface (e.g.,
mouth of the urine container).
STEP
3
Wait
for colored bands to appear. Depending on the concentration of LH in the test
specimen, positive results may be observed in as short as 40 seconds. However,
to confirm negative results, the complete reaction time (10 minutes) is
required. Do not read results after 30 minutes.
INTERPRETATION
OF RESULTS
No
LH Surge:
Only one
color band appears on the control region or the test band is present but lighter
in color intensity than the control band. There is no LH surge even if two lines
present - as long as test line is fainter than the control line the result is
negative.
LH
Surge:
If two color bands are visible and the test band is equal to or darker than the
control band, one will probably ovulate in the next 24-48 hours. If one wants to
be pregnant, the best time to have intercourse is after 24 but before 48 hours.
Invalid:
Uncertain Results: No visible bands in the control and test regions. Make sure
to follow the above specified instructions for optimum results.
