Information for patients arriving for laboratory and medical imaging examinations
This page has information on laboratory and imaging examinations and how to prepare for them. Links to the arrival and patient instructions are at the bottom of this page.
Our appointment booking instructions are for patients in the HUS area. We have compiled separate instructions for patients in the Kymenlaakso and South Karelia wellbeing services counties. You find these in the bottom of this page.
- You must always have a referral from a physician for laboratory and imaging examinations. It is your physician’s decision whether to send you to be examined. Your physician will either create the referral electronically or give it to you on paper.
- In a referral for laboratory examinations, the physician will determine which tests will be taken.
- In a referral for imaging examinations, the physician will describe your principal symptoms, findings, and examinations already performed.
Referral from a Private Physician
- If you have a referral provided by a private physician, you are entitled to the services of certain HUS laboratories. Here you find more information about laboratory tests with a referral from a private physician.
- We do not perform imaging examinations on referral from private physicians.
- Many examinations are performed at our laboratory and imaging services, some of them very different from one another. Some examinations require no preparation, while others require very specific and detailed preparation. Because of this, there are separate instructions for each type of examination.
- You may be given one or more instruction leaflets when you are about to come in for examinations. You should read them well in advance, because they contain a lot of important information.
- For some examinations, you will receive an appointment confirmation stating the time and place.
- The patient instructions describe details of the examination: how you should prepare, what will happen, what you should do afterwards, and how you will receive the results.
- Barrier-free access to our service locations varies, so please check the details before coming in for examinations. We have compiled information on barrier-free access on the Service Map. The details for each service location contain information on barrier-free access. This information is available in Finnish, Swedish, and English.
- You may search by specific barrier-free access criteria, such as accessibility by wheelchair, or if you have a vision or hearing impairment. This will highlight if there are any accessibility issues for you to particular service locations.
- You may select the route to your chosen service location on the Service Map based on the mode of transport you will be using. If you set barrier-free access criteria in the map service, you will be shown if there are any accessibility issues along the route you have selected.
Patient lifts
- A patient lift is available at many of our imaging service locations, e.g., to transfer patients from a wheelchair to an examination table.
- If you need to use a patient lift, please call in advance to the relevant unit. This will ensure that the patient lift is available.
- Laboratories perform examinations such as blood group and antibody screenings during pregnancy, and glucose tolerance tests. Most laboratory examinations can be performed without restrictions during pregnancy.
- If you know or suspect that you are pregnant and you receive a referral for a medical imaging examination, let your attending physician know or, at the latest, inform the imaging unit staff when you come in for your examination. We can then select the imaging method best suited for your condition.
- When you bring a child in for laboratory or medical imaging examinations, you should discuss this with the child in advance and explain what is going to happen.
- If your child is coming in for laboratory tests, you can review the children's sampling guide in advance.
- In medical imaging, basically the same imaging methods can be used for children as for adults, but they will be performed in a child-friendly way.

To book an appointment for a child

- A physician or nurse will agree with you how your examination results will be delivered to you: at an appointment, by letter, by phone, or online in Omakanta.
- Most laboratory examination results will be delivered to your attending physician, with no separate statements appended. In laboratory examinations, the results are often evaluated in comparison to reference ranges (‘normal values’). However, there are cases where interpretation may be more complicated and an evaluation by the physician ordering the examination is required.
- In the case of X-rays and other medical imaging examinations, a statement is written up and delivered to your attending physician.
In MyKanta and in Maisa, test results are generally displayed immediately once the results are ready, with the following exceptions:
- There is a two-week delay for radiology reports and laboratory tests for which a written opinion is given.
- For clinical genetics, the delay in test results is 30 days.
- For some specialized tests the delay may be even longer as the analysis may contain several stages and takes a long time.
- The doctor responsible for the patient's care has set a time when the results will be displayed that differs from the default.
If you have visited a laboratory on referral from a private physician, the examination results will be delivered by mail to you, to your physician, or to both. These results are not transferred to Mykanta.
You find more information about interpretation of laboratory reference ranges in the Health library (in Finnish)
Laboratory tests
- You can book an appointment for our laboratories online or through our customer service. If you book an appointment, you will be admitted promptly and at a time of your choosing.

- If you have a referral provided by a private physician, you are entitled to the services of certain HUS laboratories.
- We charge a fee for sampling and tests. The tests are not eligible for Kela compensation.
Here you find the laboratories that serve customers with a referral provided by a private physician.

At some laboratories, supplies can be collected at a self-service point. You will be given sampling instructions.
- It is important to follow instructions when taking a urine sample. Read the patient instructions to see how to prepare for the examination and what information the laboratory needs to have about the sample.
- If you have received the sampling kit and instructions from the laboratory for sampling at home, prepare to inform the laboratory of the time when you took the sample and the ‘bladder time’, i.e. how long it was since the previous time you urinated. These details need to be entered on the form given to you with the sampling kit in addition to your personal details.
- For some examinations, you need to collect urine over a given period of time. You will always be given separate instructions for such examinations.
