When does ovidrel leave your system?

How long does Ovidrel stay in your body?

Ovidrel (choriogonadotropin alfa) is an injectable fertility drug. After you take it, the medication is cleared fairly quickly and is generally considered to stop having meaningful biologic activity within about a day, with trace amounts potentially detectable on urine tests for longer.

How long until Ovidrel is out enough for a pregnancy test?

Most fertility clinics advise using a “no earlier than” timing for home or blood pregnancy tests after Ovidrel because the trigger can cause false-positive results. In practical terms, many patients are told to wait about 10 days after the trigger shot before testing, since Ovidrel can still affect test results earlier than that.

How does Ovidrel affect ovulation timing vs. drug clearance?

Ovidrel’s main purpose is to trigger ovulation. Because ovulation typically occurs about 36 hours after injection, its key effect is largely done by the time ovulation has already happened, even though testing interference can last longer than the trigger’s immediate biologic activity.

What could make clearance/testing interference longer or shorter?

Timing can vary with:
- Your sensitivity and type of test (urine vs blood, and test brand)
- How closely testing follows the trigger date
- Individual differences in metabolism and how quickly hCG is cleared

If you tell me the date/time you took Ovidrel and whether you’re using a home urine test or a blood test, I can help you map your specific testing window.
