What Your Lab Report Can and Cannot Tell You

A single value outside a reference range is information, not a diagnosis. Context is what makes a report meaningful.
Reference ranges are a guide
Reference ranges describe what is typical for a population, not what is correct for every individual. Small variations are common and often unimportant.
Why context matters
Your clinician reads a report alongside your symptoms, history and previous results. That is why interpreting a value on its own can be misleading.
Questions worth asking
Bring your report to the consultation and ask what it changes, if anything.
