Test catalogue

/tests is the catalogue — what this laboratory offers, and what each test costs in time. /tests/new adds one, /tests/:testId shows it and /tests/:testId/edit changes it.

Orders reference the catalogue rather than free text. That is what lets a haemoglobin ordered here be recognised elsewhere, and it is what makes a panel more than a list of words.

:::info The catalogue is yours LabFlow ships no pre-loaded national test menu. Shipping one would mean shipping somebody else's clinical decisions as your default. :::

What a catalogue entry carries

FieldNotes
NameWhat appears on a worklist and a report
CodeShort, upper case, unique in this catalogue
LOINC codeFormat NNNNN-N. The check digit is part of it
DepartmentWhich bench owns it
InstrumentWhere it physically runs. Two analysers may run one method — the range follows the method, the quality control follows the instrument
MethodRecorded on every result, because a range belongs to a method as much as to a patient
ContainerTube type and cap colour, as the phlebotomist sees it
StorageHow the specimen must be held
UnitSee the warning below
Reported precisionReported precision, not analyser precision. Reporting more digits than the method supports invents confidence
Critical valueA value where delay causes harm. It escalates to a named clinician and holds release until the escalation is acknowledged
TurnaroundDerived from the median transport time measured on this site
NotesRich text, shown on the catalogue row and on the ordering screen

:::danger Changing a unit is not a conversion Changing a unit later does not convert released results — it changes what the next one means. A unit change is normally a new test definition, not an edit. :::

Leaving the critical value blank

Blank means this test never escalates. That is a decision, not a default, and it is worth making on purpose.

Three states, and why nothing is deleted

StateOrderableNotes
PlannedNoDefined and not yet offered
ActiveYesIn use
RetiredNoNot deleted — historical results reference it

A retired test is not editable. Its definition has to keep meaning what it meant when a result was produced against it.
