Information guideline for customers

Correct preparation before blood sampling is important for reliable results. Remember to inform the staff if you have failed to follow any of the guidelines.

Some of the analyses require fasting. This is informed by small case letter f. Fasting means that you must avoid eating and drinking for 12 hours before taking the blood sampling tests. One is allowed to drink a small glass of water in the morning. The most common analyses that require fasting are blood sugar (fP-Gluc). For lipids such as cholesterols (P-Chol) and triglycerides (P-Trigly) fasting is not obligatory but recommendable.

Some analyses require that the sample is drawn at certain time of the day. For example thyrotropin (S-TSH) is recommended to be taken in the morning between 8 am and 10 am and cortisol (S-Korsol) is recommended to be taken between 7 am to 9 am.

Drinking alcohol is forbidden the day before blood sampling.

Avoid smoking and drinking coffee the night before.

You can take your medicine normally in the morning. The only exceptions are products that contain substances which are the target for the measurement (e.g. thyroid medicine and vitamins). These medicine should be taken after blood sampling.

Avoid hard work.

Take 15 minutes to sit down and stay relaxed prior blood sampling, so that your blood circulation will become steady.
