Collection: Ovulation Test Strips-Extra Sensitive

Ovulation strips, also known as ovulation predictor kits (OPKs) or ovulation tests, are tools used by individuals who are trying to conceive or monitor their menstrual cycles. These strips detect the presence of luteinizing hormone (LH) in urine. LH is a hormone that surges just before ovulation occurs.

Here's how ovulation strips work and what they can tell you:

1. LH Surge Prediction: As a woman's body prepares to ovulate, the level of LH in the body increases. This surge in LH typically occurs 24-48 hours before ovulation. Ovulation strips can detect this surge, helping predict the most fertile days in a woman's menstrual cycle.
2. Timing for conception: By identifying the LH surge, ovulation strips can help couples time intercourse for the days when the woman is most likely to conceive. Sperm can live for a few days in the female reproductive tract, so having intercourse in the days leading up to ovulation can increase the chances of fertilisation.
3. Confirming ovulation: Ovulation strips provide indirect evidence of the approaching ovulation, but they do not confirm that ovulation has actually occurred. Some women may experience an LH surge without releasing an egg. Other methods, such as tracking basal body temperature or changes in cervical mucus, can be used in conjunction with ovulation strips to more accurately pinpoint ovulation.

It's important to follow the instructions provided with the ovulation strips carefully to ensure accurate results. Keep in mind that various factors, such as certain medications or medical conditions, can affect the accuracy of these tests. If a couple is having difficulties conceiving and have been trying for 12 months or more without success, then consulting with a healthcare professional or fertility specialist is advisable.

Using ovulation test strips is a relatively simple process. Here's a step-by-step guide on how to use them:

1. Choose the right time to test: Start testing a few days before you expect to ovulate. The exact timing can vary depending on the length of your menstrual cycle. Ovulation typically occurs around the middle of the menstrual cycle.

2. Gather your supplies: Ensure you have the ovulation test strips and a clean, dry container for collecting urine.

3. Read and follow the instructions: Carefully read the instructions that come with the ovulation test kit. Different brands may have slightly different procedures.

4. Choose the right time of day: The best time to test is usually in the afternoon, as LH surges often occur in the morning and it takes a few hours for the hormone to appear in urine.

5. Collect urine: Collect a urine sample in a clean, dry container. Some ovulation test kits provide a small cup for this purpose. The container does not need to be sterile.

6. Dip the strip: Remove a test strip from its foil pouch or container. Dip the absorbent end of the ovulation strip into the urine for the amount of time specified in the instructions. If the Ovulation test strips are in a container make sure you replace the lid securely on the container to keep the remaining test strips from absorbing moisture from the air.

7. Wait for results: Place the strip on a clean, flat surface and wait for the designated amount of time (usually a few minutes) for the results to appear. A control line will show whether the test is working correctly.

8. Interpret the results: Most ovulation test strips have two lines: a control line and a test line. The test line will become darker or as dark as the control line if an LH surge is detected. If the test line is lighter than the control line, the surge has not yet occurred.

9. Record the results: Keep track of your results. If you notice a surge, it indicates that ovulation is likely to occur in the next 24-48 hours

10. Continue testing: Continue testing daily until you see the LH surge or until your menstrual cycle indicates that ovulation has likely occurred. One you detect the LH surge stop testing.

Remember that individual variations and factors like stress or certain medications can impact the accuracy of ovulation test results. If you have concerns or questions, or you are not detecting an LH surge when you test, it's advisable to consult with a healthcare professional.

To ensure the accuracy of an ovulation test strip, there are certain things you should avoid before taking the test. Here are some general recommendations:

1. Do not use first-morning urine: Unlike pregnancy tests, it's often recommended not to use first-morning urine for ovulation tests. LH (luteinizing hormone), the hormone detected by ovulation tests, tends to surge in the afternoon or early evening. For more accurate results, it's advisable to test during these times.
2. Limit fluid intake before testing: Drinking excessive amounts of fluids before taking the test may dilute your urine, potentially affecting the concentration of the hormones being measured. It's a good idea to limit your fluid intake for about two hours before testing.
3. Avoid medications that may interfere: Certain medications, such as those containing hCG (human chorionic gonadotropin) or LH, may interfere with ovulation test results. If you are unsure about a specific medication, consult with your healthcare provider.
4. Minimise alcohol consumption: Alcohol can potentially affect hormone levels, so it's a good idea to limit alcohol intake before taking an ovulation test.
5. Avoid excessive exercise: Intense physical activity may temporarily elevate LH levels, potentially leading to false positives. While regular exercise is generally good for overall health, consider avoiding vigorous workouts just before taking the test.
6. Follow the instructions: Make sure to carefully follow the instructions provided with your ovulation test strips. Each brand of test kit may have specific guidelines for use, including when and how to take the test.

The sensitivity of ovulation test strips varies between brands and models. Ovulation test strips detect the presence of luteinizing hormone (LH) in urine, and the sensitivity is usually expressed in milli-International Units per milliliter (mIU/ml). A lower mIU/ml value indicates higher sensitivity.

Most ovulation test strips on the market have a sensitivity ranging from 20 mIU/ml to 40 mIU/ml. Strips with lower sensitivity are generally more capable of detecting a smaller surge in LH, providing earlier and potentially more accurate results. However, it's essential to note that extreme sensitivity doesn't always guarantee better results, as factors such as proper testing technique and timing also play crucial roles.

When choosing ovulation test strips, consider your individual needs and preferences. If you have irregular cycles or want to detect a subtle LH surge, you might opt for a more sensitive test. On the other hand, if you have regular cycles and are looking for a more cost-effective option, a slightly less sensitive test may still be suitable.
