Private Ultrasound Without a GP Referral: What Clinics Will Scan, and When to See a GP First

Every few weeks a syndicated article does the rounds promising tests you can have without a GP referral. Ultrasound usually tops the list, and on the narrow point the articles are right: many private clinics will scan you without a letter from a doctor. What they leave out is why, what the clinic asks instead, and the symptoms where arranging a scan yourself is the wrong first move.

This guide covers all three. It is the ultrasound companion to our guides on private MRI without a GP referral and X-rays without a referral.

Why ultrasound is different from X-ray and CT

The difference is legal. X-ray, CT, mammography and DEXA use ionising radiation, and every such exposure in the UK falls under the Ionising Radiation (Medical Exposure) Regulations 2017, which set out the duties of the referrer in regulation 10 and require each exposure to be justified under regulation 11. That is why a private X-ray or CT needs a referral.

The NHS says ultrasound scans do not use radiation, unlike X-rays or CT scans, so those regulations do not apply, and the same is true of MRI. That is why many clinics accept self-referral for ultrasound. Each clinic sets its own policy, and some still ask for a referral for particular scans, so the answer to the question in the title is: usually, but check.

The scans clinics commonly take on self-referral

The NHS describes ultrasound as a way to see images of the inside of your body, such as muscles and organs, used to look into symptoms, monitor conditions and guide procedures. In private clinics the self-referred requests fall into a few groups: scans of the abdomen, such as the liver, gallbladder and kidneys (see abdominal ultrasound); pelvic scans of the womb and ovaries; the thyroid and other glands in the neck; muscles, tendons and joints, such as a shoulder or an Achilles tendon; and the veins in the legs. Our guide to what ultrasound can detect goes through each area and its limits.

What these have in common is that the scan answers a contained question and the result can be acted on by you and your GP.

The clinic still asks questions

Self-referral does not mean nobody checks. When you enquire, the clinic will ask what the scan is for, what symptoms you have and for how long. A sonographer or radiologist decides whether ultrasound is the right test for that question, and a good clinic will say no, or suggest a different scan or a GP visit, when it is not.

That conversation is worth having honestly, because the person scanning you needs to know where to look. Our guide to seeing a GP before a scan explains when a GP's examination will save you a wasted appointment.

Symptoms the NHS says should go to a GP first

A few symptoms are the exception, because the NHS has a fast pathway for them that a private scan would bypass.

Breast lumps. The NHS says to see a GP about any breast lump. The GP will examine you and, if the cause is not clear, refer you to a hospital or breast clinic, where the tests may include an examination, a mammogram or ultrasound and sometimes a biopsy. The NHS adds that these tests usually show that a lump is not cancer. A private ultrasound on its own is not that assessment.

Lumps elsewhere, including the testicles. The NHS lumps page says most lumps are harmless but that it is important to see a GP if you are worried or the lump is still there after 2 weeks, and to get checked sooner if a lump is in a breast or testicle, gets bigger, is painful, red or hot, or is hard and does not move. If the GP is unsure, the NHS says they might refer you to hospital for tests such as a biopsy or an ultrasound scan. Our guide to testicular ultrasound covers that scan.

A swollen, painful leg. The NHS says to ask for an urgent GP appointment or get help from NHS 111 if you think you have a deep vein thrombosis, that you should be referred to hospital within 24 hours for an ultrasound scan, and to call 999 or go to A&E if you also feel short of breath or have chest pain. That is faster than arranging any private scan.

Pregnancy. The NHS says hospitals in England usually offer at least 2 ultrasound scans during pregnancy, at around 11 to 14 weeks and around 18 to 21 weeks, and that you do not have to have them. Private pregnancy scans do not replace them, and any worry about a pregnancy should go to your midwife or maternity unit.

And in general: if you have sudden or severe symptoms, contact NHS 111, or call 999 in an emergency. A scan appointment is not an emergency service.

What you get, and what to do with it

After a self-referred scan the report comes to you. It answers the question the scan was asked to answer; it does not examine you, take a history or arrange what happens next. If it recommends a follow-up or a referral, take it to your GP, who can act on it within the NHS. Our guides to getting your images and report and how long results take explain the practicalities.

What to check before you enquire

Before sending an enquiry, plan to confirm a short list of things with the clinic:

• That the scan you want is offered on self-referral, and whether the clinic needs anything from you first.
• Who carries out the scan, who writes the report, and whether the written report is included.
• How you receive the report and whether the clinic can send it to your GP.
• Any preparation. The NHS says the clinic will tell you if there is anything you need to do beforehand, such as drinking water so that your bladder is full, or removing jewellery from the area being scanned.
• That the clinic is registered with the regulator. The Care Quality Commission is the independent regulator of health and social care in England, and its website lets you search for a service and see its inspection report and rating.

Our guide to preparing for your scan has a general checklist.

Comparing clinics on FindScan

You can compare ultrasound clinics near you and send an enquiry; the clinic contacts you to confirm whether it needs a referral and to answer the questions above.

FindScan is a directory of independent, regulated imaging clinics: you compare clinics and send an enquiry, and the clinic contacts you. We are not a healthcare provider and nothing here replaces advice from your GP. If you are unsure whether a scan is the right next step, a GP appointment is the place to start.
