Have you been trying to get pregnant for a while and not been succesful? Have you been charting your temperature? A great tool to use in conjunction with your chart is ovulation predictor kits. Ovulation prediction kits are a very popular method of detecting ovulation. One of the benefits of using an OPK (ovulation prediction kit) is that you can predict ovulation before it occurs. Ovulation is the release of an egg from the ovary. The egg then passes into the fallopian tube where it is ready to be fertilized. In order for pregnancy to occur, the egg must be fertilized by sperm within 24 hours after its release. Immediately prior to ovulation, the body produces a large amount of Luteinizing Hormone (LH) that triggers the release of a ripened egg from the ovary. This "LH surge" usually takes place in the middle of the menstrual cycle. The ovulation test detects a LH surge that ultimately predicts ovulation within the next 24-48 period. Knowing when you are ovulating is very important because there is usually a 24-48 hour window of opportunity to fertilise the ovum. In Laboratory trials these tests have proved highly accurate at more than 99.9% in detecting a LH surge in urine samples. Our tests have a sensitivity of 20mlIU/ml in urine sample.

With basal body temperature charting you can not tell that you have ovulated until after it happens. OPKs work by detecting LH (Luteinizing Hormone) levels in your urine. Just before ovulation there is a surge in LH. When this LH surge is detected, ovulation should occur within 36 hours.

How to use an Ovulation Prediction Kit
You may use a test strip or a midstream ovulation prediction test. Both work the same way. With the test strip, you will need to dip the test strip into a container of urine and keep it in the urine for several seconds. The tests normally take about five minutes to read. There is a control band and a result band. The control band gives you a color to compare the result band to. When you test you will detect some LH at any time during your cycle. That is because you produce LH throughout your cycle. You are looking for the results to be darker or the same color as the control band. If the result band is lighter than the control band you have not ovulated.
Tips for using Ovulation Predictor Kit
  • You may want to use a temperature chart as well as using an ovulation prediction kit. By looking at previous charts, you can have an idea of when the best time to use the ovulation prediction test is.
  • Test more than once a day. Because your LH surge happens briefly, you may want to test twice a day to ensure that you do not miss seeing your surge.
  • Test at the same time each day. It does not matter what time you test but it is better to not urinate for four hours prior to testing. Try to be consistent so that you do not miss your LH surge. Read the manufacturers instructions for best results.
  • If you do not see a surge in your LH continue testing every day until you see a surge.
  • Have intercourse within 36 hours of testing positive for your LH surge.
