First Response Home Ovulation Test

What sort of ovulation test is the First Response Home Ovulation Test ?

The First Response home ovulation test is a midstream urine ovulation test that works by measuring the concentration of Luteinising Hormone (LH) in your urine.

LH is always present in your urine and increases just before your most fertile day of the month. This increase, or ‘surge’, in LH triggers ovulation which is the release of an egg from an ovary.

How does the First Response Ovulation test show the LH surge ?

The appearance of two easy-to-read purple lines in the test’s Result Window indicates your LH surge prior to ovulation.

What does the LH surge mean ?

Most women will ovulate within 24 to 36 hours after the LH surge is detected. Predicting ovulation in advance is important because the egg can be fertilised only 6 to 24 hours after ovulation. Your two most fertile days begin with the LH surge. You are most likely to become pregnant if you have intercourse within 24 to 36 hours after you detect your LH surge.

When do I do the First Response Ovulation Test ?

You may test at any time of the day, (you do not have to use first morning urine) but you should test at approximately the same time each day and reduce your liquid intake for 2 hours before testing, since drinking excessive amounts of liquids can dilute the LH in your urine.

To find out when to begin testing, determine the length of your normal cycle. The length of your cycle is from the beginning of one period to the beginning of the next. Count the first day of bleeding or spotting as day 1.

If your cycle is irregular, that is, if it varies by more than a few days each month, take the average number of days for the last 3 months. Use the chart included with the test to work out the day you should begin testing. The day you begin testing is listed below the number of days in your normal cycle. For example, looking at the chart, if your period normally begins every 28 days, you should begin testing 11 days from the beginning of your last period.

How do I do the First Response LH test ?

The First Response Ovulation Test is simple to use – just hold the test in your urine stream for a few seconds. You will soon see the purple colour moving across the Clear Top to indicate that the test is working. Look at the Result Window at 5 minutes to read your result. Follow the full instructions enclosed in the pack before carrying out the test.

When do I read the result ?

After 5 minutes, you can compare the test line to the reference line to read your result.

How accurate is the First Response Home Ovulation Test?
