In brief: Usually

Ovulation predictor kit tests detect an increase in the level of lutenizing hormone (lh).
A surge in lh occurs around 24-36 hours prior to ovulation and is part of the signal to ovulate. A positive test means you will probably ovulate. The kits are accurate >98% in detecting the lh surge. Its rare but possible for your body to send the signal to ovulate without actual ovulation happening.
