Your values appear in your account with reference ranges and an explanation of each marker.
For most tests, we recommend fasting for 10–12 hours before your appointment for the most accurate results. Water is fine. If your test does not require fasting, this will be noted in the test description.
Most of our tests use a standard venous blood sample (blood drawn from a vein in your arm). Some markers can also be tested via a finger-prick capillary sample — this will be indicated on the test page.
All analyses are performed by accredited Swedish laboratories using the same methods as hospital labs. Our partner labs hold ISO 15189 accreditation, the international standard for medical laboratory quality.
