Wondfo One Step Ovulation Test

Ovulation Tests allow you to predict when you ovulate - the time you're most likely to become pregnant!

Ovulation predictor tests work by allowing you to detect your monthly LH Surge - the sudden and dramatic increase in luteinizing hormone present in your urine just before you ovulate. LH is the hormone that facilitates ovulation (the release of the egg). When you detect your LH surge with an ovulation test, you know you are fertile! (

Since the best time for fertilization of the egg to occur is within 6 to 24 hours after you ovulate, correctly gauging your body's cycle is extremely helpful in increasing your chances of becoming pregnant. Our ovulation tests detect LH with a sensitivity of 25mIU/ml/lh - and all of our tests are individually wrapped a, with an expiry date of 2 years!

How does it work?

The LH (Luteinizing Hormone) which is in the urine of normal women will increase dramatically in the middle of the menstrual cycle. The LH increase triggers ovulation which is when the egg is released periodically from Normal fertile women. Who experts state that LH testing is  a reliable way to detect ovulation. Ovulation will occur after 24-48 hours following a positive test.

When the strip is immersed into a urine specimen, capillary action carries the specimen to migrate along the membrane. When LH in the specimen reaches the Test Zone region of the membrane, It will form a colored line. Absence of this colored line suggests a negative result.

To serve as a procedure control, a colored line will appear at the Control Zone region, if the test has been performed properly.

The test strip detects ovulation with a high degree of certainty. It is a valuable tool in helping to achieve pregnancy since it determines the period that the egg and the sperm cells will meet in the best conditions.

Ovulation may be irregular because of circunatances,emotioms and other factors in your life. You cannot presume that ovulation always occurs at the same time after menstruation. Therefore, you should test again in each menstrual cycle.

When To Begin Testing

The length of the menstrual circle is the duration from your first menstrual bleeding day to the day before the next bleeding begins.  Determine the length of menstrual circle before test.  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 a physician.  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 days period, or until the LH surge has been detected.

Cycle chart

Example:  If your cycle is normally twenty-six days, the Cycle Chart indicates testing should begin on                   day 10.  The following calendar shows how to determine day 10.

Sample Calendar

3+ = The first day of menstrual bleeding

12# = The day to begin testing (Day 10)

How To Do The Test

1.  The test strip and urine have to be at room temperature (15°C - 30°C) for testing.

2.  Remove the test strip from the sealed pouch.

3.  Immerse the strip into the urine with the arrow pointing towards the urine.  Take the strip out after 3 seconds and lay the strip flat on a clean, dry, non-absorbent surface ( such as the mouth of the urine container).

IMPORTANT:  Do not allow the urine lever to exceed the MAX (MAX Line), otherwise the test will not perform correctly.

4.  Read results in five minutes.  Do not read results after more than 5 minutes.

How To Read The Results?

LH Surge (Positive):  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 trying to get pregnant, the best time to have intercourse is after 24 but before 48 hours.

No LH Surge (Negative):  Only one color band appears on the control region, or the test band appears but is lighter than the control band.  This means there is no LH surge.

Invalid:  No visible band at all, or there is a visible band only in the test region and not in the control region.  Repeat with a new test kit.  If test still fails, please contact the distributor or the store where you bought the product, with the lot number.

Questions & Answers

1.  There is much difference between the control lines of two tests.  Is this a concern?  

       No.  Variations in the color of the control band will not affect the test result.  It is only effective to compare the color of the test band to that of the control band of the same device on the day the test is perform.

2.  Can test results be interpreted after more than five minutes?

       No.  Test results must be read at 5 minutes.  Though a positive result should not change for several days, a negative result may change to a false positive within minutes after the end of the testing period, which would not be an accurate reading.  It is always best to read the results at the 5 minute testing period and then discard the test to avoid confusion.

3.  How long should I continus to perform the test?

       At least 5 days or until the LH surge has been detected.

4.  A pink background color and vertical streaking appeared in the result area during the testing period.  Is this a concern?

       No.  Each urine sample will vary in its chemical makeup, as will the humidity of the air in testing chamber (room).  Such variations in physical conditions can cause the vertical in physical conditions can cause the vertical streaking and/or the pink-rose background color but will not affect the test results.  As long as the control band appears within five minutes, the test is working properly.

5.  Once I see a positive result, when is the best time to have intercourse?

       Ovulation is likely to occur within 24-48 hours.  This is your most fertile time.  Sexual intercourse is advised within this time frame.
