Do I Need a Referral for an Ultrasound? When You Need One & When You Don’t

Ultrasounds are a safe and painless way to see inside your body. They’re often used to check on things like pregnancy, pain, or lumps. But many people ask the same question: Do I need a referral for an ultrasound? The answer depends on a few factors—like where you live, the type of scan, and how you're getting it done. Here’s a simple guide to help you understand when you need a referral and when you don’t.

When You Need a Doctor’s Referral for an Ultrasound

In most cases, a doctor’s referral is needed for ultrasounds done through public healthcare. This includes scans booked at a hospital or a diagnostic imaging center that bills the government.

You will likely need a referral if:

• Your doctor wants to investigate a health concern
• You need a diagnostic scan like a pelvic, abdominal, or thyroid ultrasound
• You want the cost to be covered by your health card (OHIP in Ontario)
• You’re getting an ultrasound at a public clinic or hospital

Referrals help ensure the ultrasound is done for the right reason. The doctor also gets your results directly and can explain the next steps.

When You Can Get an Ultrasound Without a Referral

Some private ultrasound clinics allow walk-in or self-booked appointments. These are great for people who want answers fast or don’t have time to wait for a doctor’s referral.

You may not need a referral if:

• You’re using a private ultrasound clinic
• You’re booking a 3D/4D pregnancy scan for personal viewing
• You’re paying out of pocket and don’t want to wait
• You need a same-day ultrasound scan or quick results

Look for services like:

• walk-in ultrasound services
• ultrasound without referral
• no referral ultrasound scan
• private ultrasound clinic
• get ultrasound results fast

Keep in mind: If something serious is found, you'll still need to speak with a doctor. Private scans are helpful, but they don’t replace medical advice or follow-up.

How to Get an Ultrasound (With or Without a Referral)

If you’re not sure where to start, here are some easy steps:

• Talk to your doctor. They can assess your symptoms and give you a referral.
• Search for a diagnostic imaging center near you. Many centers accept referrals and offer quick booking.
• Check for private clinics. Look up affordable ultrasound services or clinics that allow walk-ins.
• Schedule your appointment. Use search terms like book ultrasound appointment or schedule medical imaging appointment to find fast options.
• Ask about costs. Some private scans are not covered by insurance or OHIP, so ask upfront.

Why Referrals Matter for Medical Imaging

Referrals ensure you get the right type of ultrasound at the right time. They also help coordinate care, since your doctor will follow up on the results. But for those looking for quick answers or extra peace of mind, private ultrasound options without referrals can be helpful.

What If You’re Still Unsure?

If you're asking, “Do I need a doctor’s referral for a diagnostic imaging ultrasound?” here’s a quick tip: If it’s for a health concern and you want it covered by OHIP, you’ll need a referral. If it’s for peace of mind, pregnancy viewing, or you want fast results, private clinics are a great option. The CDNcare team services Ottawa and surrounding areas.
