Practical guide
Reading your blood results
A blood result consists of numbers next to a reference range. Below you read how to read it and why interpretation by a doctor matters.
What is a reference range?
Next to each value is the laboratory's reference range: the values found in most healthy people. This range can differ per laboratory and per person (age, sex). That is why Bloodworks always shows the range of your testing laboratory and we do not use our own fixed limits.
An abnormal value, what now?
A value outside the range does not automatically mean something is wrong, and a value within the range does not rule everything out. One measurement is a snapshot. At Bloodworks a doctor interprets your result and gives context; for significantly abnormal values we proactively make contact. Always discuss the result with your (GP) doctor.
Frequently asked questions
Why does the reference range differ per laboratory?
Laboratories use different methods and equipment. That is why a value should always be assessed against the range of the performing laboratory.
My value is slightly abnormal, is that bad?
Not necessarily. A slight deviation can fall within normal variation. A doctor assesses the value in the context of your situation.
Do I get an explanation with my result?
Yes. At Bloodworks a doctor interprets your result in understandable language, with concrete next steps where needed.
