General patient education, not a diagnosis or an individual treatment plan. A qualified clinician should assess your symptoms and advise you.
What lab results can tell you
A result marked outside the reference range can be worrying, but it does not automatically establish a disease. Laboratory findings need to be considered alongside symptoms, medical history and sometimes repeat testing.
Laboratory tests help investigate symptoms and monitor health, but they are one part of the assessment rather than a complete diagnosis.
Reference ranges vary between laboratories. Healthy people can sometimes have results outside a range, and results inside a range do not rule out every illness.
Prepare for a useful discussion
Ask whether preparation, medicines or other factors may affect interpretation. Seek urgent care for severe symptoms rather than waiting for a routine report.
Preparing for the next step
Bring the complete report, including units and reference ranges, and previous results if available. Tell the clinician whether you followed preparation instructions and which medicines you take. Do not start or stop treatment solely because of a highlighted number in a report.
Questions for your consultation
- What does this result mean in my clinical situation?
- Do I need a repeat test or any change to my care plan?
