LH increases dramatically just before women's most fertile day of the month in a process commonly referred to as the "LH Surge" This LH increase triggers ovulation, which means an egg is released from woman's ovary. What time of day should I test?The best times to test are between 11am and 3pm and 5pm and 10pm. If you want to make sure that you catch your LH surge, you may want to test twice a day, once in the earlier time frame and the other in the later time frame. Please keep in mind that while you may have the initial surge of LH earlier in the day if testing via blood tests, you will not get a positive result on the ovulation test until 4-5 hours later when the surge actually reaches your urine. Be sure to test at the same time each day.How long after my LH surge should I ovulate?Ovulation tests detect the ovulation hormone, luteinising hormone (LH), which rises or 'surges' 24-36 hours before you ovulate. Once I detect my LH surge, when should I have intercourse?Have sex during the 48 hours following your LH Surge to maximize your chances of getting pregnant during this cycle.Special ConsiderationsSome prescription drugs, such as menotropins may affect the test result. Certain rare medical conditions or the onset of menopause can cause elevated levels of LH. Some women do not ovulate every cycle and they will not see any increase in the level of LH hormone during these non-ovulating cycles. Women with Poly Cystic Ovary Syndrome (PCOS) may not get reliable results from ovuluation tests. Please check with your doctor if you are unsure. Negative - No LH Surge: Only one color band appears on the control (C) region or the test (T) band is much lighter than the control band. There is no LH surge. Postive - LH Surge: If two color bands are visible and the test (T) band is equal to or darker than the control (C) band, ovulate will probably take place within the next 24-48 hours.Invalid: No visible band at all. The control band will not appear if an insufficient volume of specimen is added into the test kit. Proper procedures may not have been followed in performing the test. Repeat with a new test kit. Please consult above instructions and follow precisely. The most common reason for an invalid test result with a midstream test is that urine has splashed into the interpretation window. This prevents liquid from properly “wicking” up the test and through the band of dye. Please note that invalid results can nearly always be avoided by placing your thumb over the interpretation window while holding the test in the urine stream.No LH SurgeNo LH SurgeLH SurgeLH SurgeInvalid INTERPRETATION OLH Surge: If  All items are CE marked and come individually foil wrapped.
