Ovulation Test Instructions | For positive, negative, and invalid result

Here we are giving fully of Ovulation Test Instructions. It will be easy to guess the positive, negative, and invalid result. Strips are easy to use.

Ovulation Test Instructions

Calculate when to start testing using the chart. First, calculate the length of your average menstrual cycle. Your menstrual cycle length is the number of days from the first day of your period to the last day before your next period starts. NOTE: If your cycle is irregular, you may want to use your shortest cycle length to determine when to test.

EXAMPLE: Your average cycle length is 28 days. Your period started on the 2nd day of the month. The chart shows to start testing on cycle day (CD) 11. Beginning with the 2nd day, count ahead 11 days on the calendar. You would begin testing your urine on the 12th of the month.

NOTE: If your menstrual cycle typically exceeds 40 days, or is shorter than 21 days, you should consult your physician as to the proper day to begin testing.


Ovulation Test Stop LineFirst morning urine should NOT be used with this test. For best results, you should test around the same time each day. You should reduce your liquid intake approximately hours prior to testing.
Urinate into a clean, dry cup or container.
Remove the test strip from the pouch.
Hold the test strip in a vertical position with the arrows pointing downward. Dip the test into the urine approximately 1/4 inch and hold it there for at least 5 seconds. Longer dipping times will not produce false results. Do not dip past the stop line.
Remove the test strip and lay it down flat. Wait 5-10 minutes.


While you are waiting for your results, you may notice a colored solution moving across the windows. This is normal. You need to wait 5-10 minutes to read the results. Do not read the results after 30 minutes. To determine your results, compare the color intensity of the test line to the control line as follows:

Ovulation Test Comparison Chart

Positive = LH Surge:

If 2 lines are visible and the test line is similar to or darker in color compared to the control line, your LH has surged and you will probably ovulate in the next 12 to 36 hours. Once you have detected your LH surge, there is no need to continue testing.

Negative = No LH Surge:

If 2 lines are visible but the test line is lighter than the control line, your LH level has not reached the threshold to fire a positive result. Also, if no test line is visible and 1 control line is visible, your LH level has not reached the threshold to fire a positive result. You should continue testing daily.


If a control line does not appear, the test is invalid. Insufficient specimen volume or incorrect test performance is most likely the reason for an invalid result. This can be caused by not holding the test strip in the urine for at least 5 seconds or by dipping passed the stop line. If you receive an invalid result, dip the test strip in the urine for an additional 5 seconds and wait 5-10 minutes. Read the results again. If there is still no control line, the test is invalid and should be discarded. Review the instructions and then, following them exactly, repeat the test using a new BFP Ovulation Test Strip.


Read all the information before performing the test. Do not open the foil pouch until you are ready to begin the test. Not every woman ovulates mid-cycle, therefore, you may not see a positive result during your first 5 days of testing. Continue testing with the BFP Ovulation Test Strip to detect your LH surge.

Some prescription drugs may affect the result such as menotropins for injection (Pergonal®) and danazol (Danocrine®). If you are using Clomiphene Citrate (e.g., Clomid® and Serophene®), consult your physician for possible interference with the test. Some rare medical conditions and/or the onset of menopause can cause elevated LH levels. Some women do not ovulate every cycle and will not see an increase in LH levels during these non-ovulatory cycles.
