A pathology lab report should carry the laboratory header, patient identifiers and sample details, each result with its unit and reference range, a flag for values outside range, the reporting pathologist with date and time, and a footer noting that results relate only to the sample tested.
The header
Laboratory name, address and contact details, and your logo. This is what makes the document traceable back to you, and it is the first thing a referring doctor looks at when deciding whether to trust a result.
Patient and sample identifiers
Name, age and sex, a unique patient identifier, the referring doctor, and the sample details — collection date and time, receipt time and sample type. Age and sex are not decoration here: they determine which reference range applies.
The result block
Each parameter needs four things together: the value, the unit, the reference range used, and a flag if it falls outside. A value without its unit is ambiguous, and a value without the range it was judged against cannot be checked by the reader.
Grouping by department
Where a single visit covers haematology, biochemistry and serology, group results by department rather than listing them in billing order. The reader is scanning for a pattern, not reconciling an invoice.
Approval and signature
The reporting pathologist, their qualification, and the date and time of approval. Department-wise signatures are used by many labs where different people sign different sections.
The footer
A note that results relate only to the sample tested, that the report is computer generated where applicable, and that results should be correlated clinically. This is standard practice and it protects both the lab and the reader.
Common mistakes
The ones that come back to bite.
- Adult reference ranges printed on a paediatric report
- Units missing, or inconsistent between reports for the same test
- No indication of which range the flag was judged against
- Collection time absent, so a delayed sample cannot be accounted for
- Reports released before approval because approval was a convention, not a permission
