If your GP or specialist has referred you for an abdominal ultrasound, the most useful thing to know is that preparation depends on which area they want imaged, so follow the instructions you’re given when you book. For many upper abdominal scans that means fasting for a set period beforehand, while other scans ask for a full bladder instead. This guide covers the abdominal ultrasound preparation questions we hear most at UBM Scans in Menai NSW, from fasting and clothing to what to bring and what the appointment looks like.<\/p>\n
Abdominal ultrasound preparation usually comes down to four things: whether you need to fast, whether you need a full bladder, what you wear, and what you bring with you. Which of these applies to you depends on what your referring doctor has asked to be imaged, because an abdominal ultrasound is not one single check. Depending on the referral, it may look at organs such as the liver, gallbladder, pancreas or spleen, and your referral tells the sonographer where to focus.<\/p>\n
Because the request differs from person to person, there’s no single set of rules that suits everyone. Two people booking on the same day can be given different instructions, and that’s normal. If anything in this article differs from what you were told when you booked, go with what you were told, and ring us if you’re unsure which instruction applies.<\/p>\n
It also helps to know what we don’t do on the day. We don’t diagnose, and we don’t tell you what an image means. Our role is to perform the scan carefully and send the report to your referring doctor, who then talks it through with you in the context of your health history and symptoms.<\/p>\n
Fasting before ultrasound is one of the most common instructions for an upper abdominal ultrasound. In general terms, an empty stomach can make it easier for the sonographer to see structures in the upper abdomen, and food and drink can change how some organs look on the day. That’s the general reasoning, but the length of the fast and the rules around fluids are set when you book, so please treat them as the authority rather than anything you’ve read online.<\/p>\n
When you book, it’s worth asking a few practical questions:<\/p>\n
Medications deserve a special mention. Don’t stop or change a prescribed medication on your own because you’re fasting. If you take regular medication, or you manage diabetes, speak to your GP or the prescriber about how to handle the fasting window safely. They know your health history and we don’t. Let us know about it when you book too, so that you can plan the timing of your appointment sensibly.<\/p>\n
If you’re fasting, an appointment time that suits your day matters more than it might for other scans. Our Menai clinic runs evening sessions and a Saturday morning, so a short chat when booking helps you pick a slot that doesn’t leave you going without food for longer than necessary.<\/p>\n
Some scans ask for a full bladder rather than fasting, and some ask for both. Renal and pelvic ultrasounds are examples where bladder filling is often part of the instructions, while an upper abdominal scan is more likely to involve fasting. Your referral may also request more than one area, in which case the instructions are tailored to the full request.<\/p>\n
The key point is not to guess. If you’ve been told to drink water and hold on, follow the timing you were given exactly, because arriving with an empty bladder when a full one was needed can mean the scan has to be rescheduled. On the other hand, if no one has mentioned bladder preparation, don’t start drinking extra water in case. Call us and ask. If your referral lists several areas and the preparation sounds contradictory, that’s exactly the type of question we’d rather answer before the day than on it.<\/p>\n
If you’re not sure what your referral covers or how to prepare, just ask us. We’re happy to talk it through at booking, and it takes a lot of the guesswork out of the day.<\/p>\n
Call 0423 550 063<\/a><\/p>\n<\/div>\n The best preparation is a short conversation at booking, because your instructions are written for your scan, not for everyone’s.<\/p>\n<\/blockquote>\n Comfortable, loose clothing makes the appointment easier. A two-piece outfit, such as a loose top with comfortable pants or a skirt, works well because the sonographer needs access to your abdomen and a little of the area below it. It’s sensible to avoid tight waistbands, belts, bodysuits and anything that’s awkward to adjust while you’re lying down. Ultrasound gel is used to help the probe make good contact with your skin, so avoid wearing something you’d be upset about getting a little damp.<\/p>\n For what to bring, plan on the following:<\/p>\n If you’ve been fasting, it’s reasonable to pack a snack for afterwards, but check with us first whether you should avoid eating or drinking in the waiting area before the scan.<\/p>\n Every diagnostic ultrasound at UBM Scans, including abdominal ultrasound, needs a referral from your GP or specialist. That requirement applies whether you’re searching for an ultrasound referral in Sydney from a local doctor or you’ve been referred by a specialist elsewhere. The referral tells us what to scan and why, and it’s what allows us to send the report back to the right clinician.<\/p>\n On cost, a referred diagnostic scan may attract a Medicare rebate where eligibility and item requirements apply. We can’t promise a rebate or tell you in advance what your out-of-pocket cost will be, and we’re not a bulk-billing provider, so please don’t assume your scan will be bulk billed. The sensible approach is to ask about costs when you book, so that nothing is a surprise on the day. The cost depends on your scan and your circumstances, and we’d rather explain it up front than leave you guessing.<\/p>\n If you don’t have a referral yet, your GP is the right starting point. We can’t provide one, and we can’t give you a scan on the strength of a symptom alone.<\/p>\n Knowing the shape of the appointment tends to take the nerves out of it. After you arrive and your referral is checked, the sonographer will explain what they’re about to do and answer questions about the process. You’ll then lie on an examination couch with your abdomen exposed, and warm gel is applied to your skin. The sonographer moves a handheld probe across the area, and captures images as they go.<\/p>\n A few things you may notice:<\/p>\n How long to allow depends on the areas being imaged, so ask when you book rather than relying on a general estimate. After the scan, the sonographer’s images are put into a report that goes to your referring doctor. We can’t interpret your results, and we can’t promise when a report will reach your doctor. Please book a follow-up with your GP or specialist to discuss the outcome.<\/p>\n One important note: a scan is not a pathway for urgent problems. If you have severe or sudden abdominal pain, or you feel acutely unwell, see a GP or go to an emergency department rather than waiting for a booked appointment.<\/p>\n Our main clinic is at 10 Anzac Rd, Menai NSW 2234, which suits many people across the Sutherland Shire. Current Menai hours are Monday to Thursday from 6:30pm to 8:30pm and Saturday from 8:00am to 12:00pm. We also have a second location at Macarthur Square, Campbelltown NSW 2560, which currently operates on Saturdays by appointment. That may help if you’re coming from the Macarthur area. All of our scans are performed in clinic, and we don’t offer mobile or home-visit ultrasound.<\/p>\n Because schedules can change, confirm the day, time and location with us when you book, and ask which location is available for your particular scan. Evening and Saturday sessions are handy if you’d like to fit a fasting window around work, though we’d suggest raising that when you call so we can suggest a suitable time.<\/p>\n A quick note for anyone who is also pregnant or curious about our other services: referred diagnostic scans are separate from our keepsake pregnancy scans, which don’t need a referral and aren’t diagnostic. If you’d like to understand how those scans differ, our guide to 2D, 3D and 4D ultrasound<\/a> explains the basics, and everything to know before your 3D ultrasound<\/a> covers that side of what we do. Neither applies to your referred abdominal scan.<\/p>\n Not necessarily. Fasting is commonly requested for upper abdominal scans, but the instructions depend on what your referral asks us to look at. Check with us when you book and follow those instructions.<\/p>\n<\/details>\n That depends on your instructions. Some scans allow or require water, and others don’t, so please ask when you book rather than assuming. If you’re unsure on the day, give us a call before you arrive.<\/p>\n<\/details>\n Don’t stop or change any prescribed medication without advice. Talk to your GP or prescriber about how to manage your medication around fasting, particularly if you have diabetes, and let us know when you book.<\/p>\n<\/details>\n No. Diagnostic ultrasound at UBM Scans requires a valid referral from a GP or specialist. Keepsake pregnancy scans are different and don’t need one, but they aren’t a substitute for a referred scan.<\/p>\n<\/details>\n\n
