Your question: Do out of date ovulation tests work?

In a statement to the Problem Solvers, the manufacturer of the Clearblue test agrees, saying “Ovulation tests contain anti-bodies, which are biological reagents and these can degrade with time,” adding, “If a test is used after the expiration date the result should not be relied upon.”

How long are ovulation tests good for after expiration date?

How long do they usually last? Generally, tests are good for 1 to 3 years after manufacture. A high quality, extra sensitive test may last longer than your run-of-the-mill “internet cheapie” test (as they’re called in trying-to-conceive forums; an example can be found for purchase online here).

Can I have a negative ovulation test but still ovulate?

A test may be negative if it is administered incorrectly or ovulation is yet to occur. If a cycle is longer than 28 days, additional days may be required before a positive test is achieved. However, in particular cases, even though an LH peak is detected, ovulation still may not occur.

When will I get a positive ovulation test?

Ovulation most likely occurs around day 18. You should get a positive result on an OPK a day or two before that, on day 16 or 17. It’s a good idea to start testing every day (or every other day) in the morning a few days before that, around cycle day 13.

How long should I hold my pee before taking an ovulation test?

Keep in mind that liquid can dilute the amount of luteinizing hormone (LH) in your urine. If this happens, it can appear as if you’re not ovulating when you are. So limit your intake of fluids about 2 hours before testing. It also helps not to urinate 1 to 2 hours before testing.
