Is It Possible To Have A Positive Ovulation Test But Not Ovulate?

The most accurate way to predict when you will ovulate is to use an ovulation prediction kit. It works similarly to a pregnancy test kit but you use a mid-to-late afternoon urine sample and a positive result is indicated by the appearance of a test band that is equal to or darker in color than the control band. A negative result will appear as lighter in color to the control band, or not visible at all.

What the test kit is analyzing is the level of luteinizing hormone, or LH, in your body. As you approach ovulation, your LH levels surge to prepare your body for the release of eggs from your ovaries. An ovulation predictor kit will pinpoint when your LH levels are elevated.

False positive results do happen
Unfortunately, ovulation predictor kits are not 100% accurate and you can in fact register a false positive result. What this means is that even though you are in fact, not ovulating, the kit appears to show that you are.
• Ovulation predictor kits do not provide a measurement of your LH levels. They merely tell you whether you are or are not experiencing an LH surge.
• It is possible for a woman to experience a false luteinizing hormone surges. In other words, her body will produce a surge of LH, regardless of her ovulatory activity.
• Depending upon how often you do a test, you may miss the “window period” in which the positive test result will appear. Your LH levels may surge for a shorter period than is possible to capture in the time frame in which you ordinarily take the tests.
• If you have used a urine sample that has been left to sit for some time, it may not give an accurate result because LH breaks down and dissipates in time.
• Using a first-thing-in-the-morning urine sample can result in a false positive because the LH levels become concentrated overnight.

To achieve maximum accuracy when using an ovulation predictor kit, always follow the directions on the pack precisely. If you have been charting your menstrual cycles, start testing at around two days before the middle day of your cycle and continue until you achieve a positive result.

Women with irregular cycles may find that ovulation predictor kits become expensive since they are unable to pinpoint the few days in which ovulation is likely and so use more test strips than they’d like to. Again, charting the cycle is an excellent way to familiarize yourself with your body’s rhythm.

If you believe you have achieved a false positive result, go over the pack instructions again, and also examine the methods and timing you used to take the test. If still in doubt, you may be able to contact the manufacturer if there is a contact number on the pack.
