Lab report guides: what the parts of a blood test report are
Twelve plain guides to the paper a lab hands you: how a report is laid out, what ranges, flags and units are, what the lines of a blood count, lipid panel and metabolic panel measure, and how to keep the numbers in a spreadsheet. They describe. They do not interpret.
Not medical advice. This guide describes what the parts of a lab report are and how they are recorded. It does not say what any result means for a person, and it does not recommend treatment, supplements or targets.
Reading a report
What a report contains and what its marks say.
Layouts and units
Why two reports of the same test can look different.
Panels, line by line
What each line of a common panel measures.
Keeping records
Keeping the numbers, and keeping them private.
Questions people ask
What are these guides?
Plain descriptions of the parts of a lab report: columns, ranges, flags, units, the lines of three common panels, and how to keep the numbers in a spreadsheet. They describe and do not interpret.
Are the guides medical advice?
No. They never say what a result means for a person and do not recommend treatment, supplements or targets. For that, ask a clinician who knows your history.
Where should I start?
Start with how to read a lab report, then reference ranges and flags. The panel guides list the lines of a blood count, a lipid panel and a metabolic panel.
Will the guides match my lab's layout?
They describe common layouts and say typically where practice varies. Always read the headings and notes on the report you hold.
How do I move report numbers into a spreadsheet?
Read the guide on tracking blood work in a spreadsheet, then use Lab results to Excel or the free blood test tracker template.
Do the guides replace a lab's own documentation?
No. A lab's footnotes and documentation say how it measured and calculated each line. The guides only explain the common patterns.
