HLN / 001

Written for medical laboratory professionals, students, and anyone learning how hematology decisions are made at the bench.

Why this site exists

Textbooks are good at telling us what a result means in isolation. The bench rarely gives us results in isolation.

HemeLabNotes focuses on the part between seeing a flag and releasing a result: noticing which values belong together, recognising when the specimen may be misleading us, and deciding what deserves a closer look.

How the notes are written

Each guide starts with the pattern, not a catalogue of diseases. Reference ranges, instrument flags, smear findings, previous results, and clinical information all have a place—but their value comes from how they change the interpretation.

The aim is not to replace local procedures, manufacturer instructions, or clinical judgement. It is to make the reasoning visible.

A note on use

This site is educational. Always follow your laboratory’s validated methods, review criteria, critical value policy, and escalation process. Patient results require interpretation in their full clinical context.
