What laboratory tests are for
Blood and urine tests provide information that an examination alone cannot show: how the liver and kidneys are working, what your blood sugar and blood fat levels are, whether there is inflammation, what your blood count looks like and how your thyroid is working. That is why they are part of almost every consultation, from a visit to a general practitioner to specialist consultations, and they are also used to monitor treatment and chronic conditions.
Tests are done when a doctor is looking for the cause of complaints such as tiredness, frequent infections, changes in body weight or pain, but also preventively, when there are no complaints, for example once a year or as part of a comprehensive health check. For people who already have a diagnosis, such as diabetes or thyroid disease, regular checks show how the treatment is working.
The laboratory at Miren Medic Polyclinic
The laboratory is located within the polyclinic, in the same place where the general practitioners and specialists work, so a consultation and a blood test can be arranged in the same visit. It covers routine blood and urine tests, biochemical and immunological analyses, hormone profiles, including thyroid and reproductive hormones, and specialist analyses ordered by a doctor. These include, for example, the blood count, blood sugar, cholesterol and triglycerides, liver function tests and thyroid hormones.
The choice of tests is agreed with a doctor, because it depends on your complaints, your age and the treatment you take. The results are then interpreted by the general practitioner or the specialist treating you, so that they can be considered together with the examination. For patients receiving home medical care, samples for testing can also be taken at their home address. Ultrasound examinations and specialists in several fields are also available at the polyclinic, so when a result calls for it, the next step can be arranged in the same place.
Preparing for a blood test and a urine test
For most blood tests, especially blood sugar, cholesterol and triglycerides, you come in the morning on an empty stomach, after 8 to 12 hours without food. Water is allowed, but coffee, sweetened tea, juices and chewing gum should be avoided until the blood sample has been taken. On the day before the tests, avoid alcohol, heavy meals and strenuous exercise, as they can change some values. If you are coming on an empty stomach, bring something to eat and drink for after the blood test, especially if you have diabetes.
Do not stop medicines you take regularly on your own. For some tests, such as thyroid hormones, it matters whether the medicine was taken before or after the blood sample, so please check this when you book. Some hormones are tested on a particular day of the menstrual cycle, as your doctor advises. For a urine test, the first morning urine is usually collected, midstream, in a sterile container.
If you have a cold or a raised temperature, mention it before the blood sample is taken, because an acute infection can change some values, for example the blood count and CRP. If you have felt unwell or fainted during a blood test before, tell the staff in advance so that they can be prepared.
Results, and when not to wait for tests
A laboratory report usually lists reference ranges next to each result, and these can differ from one laboratory to another. A single value outside the range is not a diagnosis in itself: it is interpreted together with your complaints, the examination and previous results. When monitoring a chronic condition, how values change over time matters more than a single result, so it is worth keeping earlier results and bringing them to check-ups. If you would like to understand what particular parameters mean before talking to your doctor, our blood count interpreter and the guides to TSH values and HbA1c values can help.
Laboratory tests are meant for planned diagnostics and monitoring. With severe chest pain, difficulty breathing, signs of a stroke, heavy bleeding or a sudden deterioration in your general condition, do not wait for a test appointment: call an ambulance on 194 straight away. If a result worries you but the situation is not urgent, book a consultation with a general practitioner or a specialist and go through the results together.

If you had the tests done without a consultation, you can bring the results to a general practitioner.
When should I have laboratory tests?
