Can you use ovulation test with first morning urine?

Does it matter what time of day you take an ovulation test?
You can take an ovulation test at any time of day. But the morning may give you the best results. To boost your chance of an accurate reading, don’t drink a lot of fluids in the four hours before a test. This helps make sure your urine and LH levels are concentrated.
When should I test my urine for ovulation?

What time of day does LH surge happen?
The LH surge triggers the egg to fully mature and to be released from the follicle. A study of 155 cycles from 35 women demonstrated that the onset of the LH surge primarily occurs between midnight and early morning (37% between 00:00 and 04:00, 48% between 04:00 and 08:00).
What time of day is LH highest?
Ovulation is related in time to the onset of the LH surge, and occurs 40–45 h following the onset of this surge as detected in blood. The commonest time for the LH surge (as detected in blood) to commence is between 05:00 and 09:00.
Do you ovulate at night or in morning?
Do you ovulate in the morning or night? Research shows that the LH surge occurs in the evening to early morning. Once you have ovulated, you have 12-24 hours for your egg to be fertilized by sperm.
Can LH surge happen overnight?
On average, the LH surge the OPKs detect occurs about 24 hours before ovulation, but the timing of the surge may vary from about 16 to up to 48 hours.
What time of day is egg released during ovulation?
When the amount of estrogen reaches its upper threshold, the egg is ready for release. The brain then produces a surge of luteinizing hormone (LH), triggering ovulation. The release of the egg from the follicle and ovary happens about 24 hours later (10–12 hours after LH peaks) (13, 17).
Can you ovulate the same day as LH surge?
The LH surge indicates ovulation will occur at some point within the next twelve to forty-eight hours (on average). The window is large because it is different for everyone. Some people ovulate the same day as the LH surge and some ovulate two days after the surge.
Can you test for LH surge in the morning?

How accurate are urine ovulation tests?
How accurate are ovulation tests? When taken correctly, ovulation tests are approximately 99% accurate in detecting the LH surge that precedes ovulation. However, these tests cannot confirm whether ovulation actually occurs a day or two later. Some women may have a surge in the LH hormone without releasing an egg.
How many hours does ovulation last?
Ovulation occurs once a month and lasts for about 24 hours. The egg will die if it’s not fertilized within 12 to 24 hours. With this information, you can start tracking your fertile days and improve your chances of conceiving.
