Why you might see this term
Blood tests help investigate hormonal patterns; urine ovulation predictor kits look for an LH rise for a different purpose.
What to keep in mind
A positive urine LH test suggests a surge, but does not prove that an egg was released. An LH-to-FSH ratio alone does not diagnose PCOS.
