When someone is using a hormone patch, it is best to test halfway between the cycle of patch application. For example, if a person is applying the patches weekly, then test on day 3 or 4. This would hold true if the person is applying them bi-weekly. In other words, try to collect a urine sample about halfway through the patch lifespan.
When should someone using hormone patches collect a urine sample for Vibrant's Urine Hormones test?
