Test (LH) Instructions:

How
the Ovulation Test Works:
This
test will help you find the time when you are most able to become pregnant.
It can help you plan your pregnancy. Luteinizing hormone(LH) is always
present in human urine. It increases just before a woman’s most
fertile day of the month. This LH increase triggers ovulation. During
ovulation an egg is released from the ovary. Because the egg can be
fertilized only 6 to 24 hours after ovulation [1], detecting ovulation
in advance is very important. Please read these instructions fully.
BEFORE
YOU BEGIN TESTING:
1.
Read this entire pamphlet carefully. Do not open the foil packet until
you are ready to perform the test.
2. Do not use the test after the expiration date printed on the package.
3. Store at room temperature 4-30oC (40-86oF). Do not freeze.
4. The test can be used any time of day.
5. Select a well-light room with a clean, flat surface for performing
the test.
WHEN
TO BEGIN TESTING:
1.
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.
2. The best time to collect your urine is between 10am - 8pm.
3. Collect urine at about the same time each day. Use a sterile container
each time
4. 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 the ovulation tests:

TEST
PROCEDURE
STEP
1
Bring the test pouch to room temperature (18-30?C). To begin testing,
open the sealed pouch by tearing along the notch. Remove the test from
the pouch.
STEP
2
Holding the strip vertically carefully dip it into the specimen. Do
not immerse the strip past the maximum line (figure 1).
STEP
3
The strip can be removed from the specimen when red dye begins to migrate
through the Result Window. Interpret test results at 5 minutes.
INTERPRETATION OF RESULTS
Interpret
the test results at 5 minutes. Do not read after 5 minutes
The right section of the Result Window indicates the test results. If
another purple colored band appears at the right section of the result
window, this band is the Test Band (T).No LH Surge: The presence of
a purple Control Band and a lighter purple Test Band means that an increase
in LH is not detected.
The presence of only one purple colored band (Control Band) within the
Result Window indicates that no LH increase has been detected (Figure
2).
LH Surge: The presence of two purple bands of similar color and darkness
within the result window, no matter which one appears first, means that
an increase in LH is detected (Figure 2).
The Test Band may be darker than the Control Band (Figure 2).
Invalid - The test result is considered invalid if no purple colored
band is visible within the Result Window (Figure 2). Not following the
directions correctly or using a test after the expiration date can cause
invalid results.
FUNCTION
OF THE CONTROL BAND
The
Control Band is used as a reference. If the Test Band is similar in
color or darker than the Control band, the ovulation test result is
positive. If the Test Band is lighter in color than the Control Band,
the test result is negative. The Control Band is also used for procedural
control to determine if the test reagent is working properly.
Important: After you have read your result, the test
should be discarded.After each test, you must decide if you are having
an LH surge. If your test result is positive, you are probably having
an LH surge. An LH surge can last from one to three days
If your test result is negative, you are probably not having an LH surge.
Remember that a pink-rose test band lighter than the control band shows
that there is only a very low level of LH in your urine.
Questions
and Answers
Q: When can I take the test?
A: After you determine the best day to start testing based on your monthly
cycle (see When to Begin Testing), you can do the test any time that
day. You do not have to use your first morning urine. However, you should
do the test at about the same time each day. Reduce your liquid intake
for 2 hours before testing.
Q:
What if no band appears in the result window?
A: If no band appears in the result window after 5 minutes, the result
is invalid and you should repeat the test using another test kit. (see
Invalid Results)
Q:
I have used all five tests and I do not see a surge, What do I do?
A: Since not every woman ovulates mid-cycle, you may not detect the
LH surge in the first five days of testing. This could mean you have
not ovulated yet and you should continue testing with additional ovulation
tests.
Q:
I have tested for 8 days and I did not see my LH surge, what is wrong?
A: About 90% of ovulating women with regular cycles will see their surge
during 8-10 days of testing [2]. If you do not, it could mean that you
have not ovulated this month. If you are having a short cycle this month,
it is possible that you have ovulated before you started testing. If
you are having a long cycle this month, you may not have ovulated yet.
You may continue testing or test again next month. Don't worry, it is
normal to have an occasional short or long cycle, or to have a cycle
without ovulating.
Q: I have used the ovulation test for three months, and each
month I have seen a surge and have had intercourse that day or night.
I have not become pregnant yet. What is wrong?
A: First, it is important to remember that it can take normal, healthy
couples many months to become pregnant. There are many factors which
affect your ability to become pregnant even if you have been able to
have intercourse during your most fertile time. If after several months
you have no success, consult your physician.
Q: What could interfere with my test result?
A: If you are actually pregnant, have recently been pregnant, or have
reached menopause you may get a misleading result. Some prescription
drugs, such as menotropins for injection and danazol may affect the
result you see, please consult your physician if you question your test
results.
Q:
If the Ovulation Test can determine my most fertile time, why can't
I use it for contraception?
A: Sperm can survive up to 72 hours, and this test predicts your LH
surge only up to 24 to 36 hours in advance. Therefore, if you have intercourse
before you discover your surge, the egg can still be fertilized.
