1.  Remove a Testing Device from the foil pouch by tearing at the notch and place it on a level surface. 

2. Holding a sample dropper vertically, add 2-3 drops of the urine specimen to the sample well (with an arrow marked). 

3. Read the result in five minutes. Positive results may sometimes appear as early as one minute but you should wait the full 5 minutes before determining a negative result. Do not read results after more than 5 minutes.

Negative (No LH Surge) :

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.

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


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.

Qus: My cycle length is outside of the range show in the table. How will I know when to start testing?

Simple start testing 17 days before you expect you expect your next period.

Qus: I do not know my usual cycle length. How will I know when to start testing?

If you wish to star using the test before knowing your cycle length, we recommend you start testing on day 10.

Qus: What time of day should I take the test?

You may test any time of day, but you should test at approximately the time each day. You should not have urinated for at least 4 hours before testing.

Qus: 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 performed.

Qus: Can test results be interpreted after more than five minutes?


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.

Qus: How long should I continue to perform the test?

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

Qus: Do alcohol or common medications affect the test?

No, but you should consult your physician if you are taking any medication.

Qus: 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.

Qus: Will the amount of liquid I drink affect the result?

We suggest that you limit your fluid intake for about two hours before you collect your urine. Because heavy intake of fluids prior to testing will dilute the hormone in your urine.
