Instructions for sample collection
Preparing for a blood test – instructions before sample collection. It is important to prepare for your blood tests correctly so that the results will be reliable and useful.
We recommend using the same laboratory if you want to compare results over time. This is because the reference values can differ between different laboratories (Karolinska, Synlab and Unilabs).
