OVULATION (LH) TESTS
TEST DESCRIPTION
One Step LH Urine Ovulation Test is fast and easy-to-use. It is
a qualitative test that can predict when there is a LH (luteinizing
hormone) surge, and in turn, when you are likely to ovulate and
conceive. The tests are available in 3 different formats:
1. STRIP
2. CASSETTE
3. MIDSTREAM
The format applications range from professional to domestic usage.
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 below 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
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.
4. Reduce liquid intake about 2 hours before collecting your urine
as a diluted urine sample can prevent the test from detecting LH
surge.

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 (TEST FORMATS)
|
STRIP TEST
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 20seconds and lay the strip
flat on a clean, dry, non-absorbent surface (e.g., mouth of
the urine container).
|
|
|
CASSETTE TEST
Draw the urine sample into the provided pipette, and dispense
0.2ml (about 4 drops) into the round dropping well of the
cassette.
|
|
|
MIDSTREAM TEST
Hold the round end of cover with one hand. Use the other
hand to pull out the test device and expose the absorbent
window.
Point the absorbent tip downward; place the absorbent tip
in urine stream for at least 10 seconds to be thoroughly wet.
Otherwise, you can collect your urine into a clean cup and
dip half of the absorbent pad into the urine for at least
10 seconds. Re-cap the device and place it on the clean, flat
surface.
|
|
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.
