When the ovary is getting ready to release an egg, Luteinizing Hormone (LH) levels increase. First Vue Ovulation Tests monitor these levels to predict when your most fertile days of the month occur, thereby increasing your chances of getting pregnant if you have sex.
USING THE TEST
You can test at any time of the day but you should test at about the same time each day. Avoid too much fluid intake for 2 hours before testing. You will need to know your usual cycle length before you start to ensure that you test at the right time. Count the day your period starts as day 1 and count through to the day before your next period starts – the number of days is your cycle length. Once you know your cycle length, use the table at the bottom of the page to find out which day of your cycle to start testing. If your cycle is less than 21 days or more than 38 days ask your doctor for advice on when to test.
–Collect a Urine sample in a clean dry container.
–Open the sealed pouch and remove the strip.
–Put the test strip vertically into the urine sample making sure that the arrows are pointing down. Do not allow the urine level to go above the max line marked on the strip.
–Leave the test strip in the urine sample for 10 seconds.
–Take the strip out and lay it flat. For the first few seconds after wetting you should see the liquid moving up the test area causing it to go light pink. As the pink fades the control line will appear as a strong line and the result line will if present appear below this. Read the results within 10 minutes of doing the test.
Perform 1 test at approximately the same time each day over a 5-day period or until the LH surge has been detected.
Reading the Result
(LH surge detected) If two coloured lines appear on the test strip, and the colour of the test line is the same as or more intense than the control line. Both lines will be the same thickness. See Question 4 in the frequently asked questions.
If only one coloured line appears on the test strip and there is no line in the test section, then this is a negative result.
If you see 2 lines but the colour of the test line is less intense than the control line, then this is also a negative result. See Question 5 in the frequently asked questions.
If no lines appear anywhere on the test strip or only the test line appears, the test has not worked properly and is invalid. This is usually due to the strip not being wet enough. Repeat the test ensuring that the strip is immersed in the urine sample for the full 10 seconds. See Question 3 in the frequently asked questions.
