Patient and visitors Laboratory and X-ray

Please arrive at Puijo Hospital in good time for laboratory tests or at the ECG unit because it is recommended that you sit quietly for 10-15 minutes before any tests are taken. You can book an appointment online for lab tests. Customers without an appointment for the laboratory will be served in the order they arrive. Remember to take a queue number.
The laboratory is often busy from 7 to 9 a.m. so if possible do not come to the laboratory without an appointment during this period unless the procedure requires fasting or must be carried out at that particular time.
