Ovulation checks perform by detecting the presence of luteinizing hormone (LH) in urine. A optimistic end result, indicating imminent ovulation, is often indicated by a check line that’s as darkish as, or darker than, the management line. The interpretation window for these checks is normally specified by the producer, typically round 5-10 minutes. Any adjustments noticed outdoors this timeframe might not precisely mirror LH ranges.
Correct timing is important for efficient use. Studying outcomes inside the designated window ensures that the chemical reactions have stabilized and the colour depth precisely represents the hormone focus on the time of testing. Ignoring the required timeframe can result in misinterpretations, impacting household planning efforts. Whereas the check would possibly present additional coloration improvement past the beneficial studying time, this darkening doesn’t essentially point out a surge in LH and shouldn’t be thought of a sound end result.
