Hematology study guide
This hematology study guide works through the competency areas assessed on the CAMLPR exam, one subdivision at a time — what the finding means, whether it is real, and what the technologist does about it.

Where to start
A reading order written by MLTPrep, sequenced the way the work is learned rather than the way the competency chart is organised. Work through it in order, or jump to whichever stage you need.
- Stage 1
Before a single tube is drawn
Everything that has to be settled before blood is taken: the current procedure, the person in front of you, the request itself, and the barriers between you and the sample. By the end you can challenge an order that cannot answer the question, prove the patient is who the label says, and draw a specimen you would be willing to test.

- Stage 2
Is this sample worth testing?
The gate between the tube arriving and the bench accepting it — matching, accessioning, integrity, packing and queue order. By the end you can reject a specimen for the right reason, keep tube and slide tied to one patient, and decide what is worked up first when everything arrives at once.

- Stage 3
Numbers you can stand behind
Bringing the instrument, the reagents and the controls into a state where the count means something, then producing counts, coagulation results and films from that footing. By the end you can read your control and calibration data before you trust a single patient number, and set up clean work at the bench.

- Stage 4
Reading what is actually on the slide
Morphology as a skill you can defend: judge the stain, name what you see, count it properly, and capture it when someone else needs to look. By the end you can work a film systematically, including for organisms, and check that a digital image is showing you the truth.

- Stage 5
Do you believe the result?
The judgement step — where the analyser stops being right, what is artefact, what is impossible, and what a whole set of results says together. By the end you can separate the findings that change patient care from the noise, troubleshoot an instrument methodically, and hold bedside and kit results to the same standard as the bench.
8 steps →
- Stage 6
Closing the loop
Getting the result to someone who can act on it, leaving a trail behind it, and speaking up about what you saw on the way. By the end you can release and escalate appropriately, account for every test ordered, and use surveys and incident reporting to keep the bench honest.

Browse by competency area
The same material filed against the eight areas of the CAMLPR competency profile, for when you want to check one off directly.
Specimen Collection
HEM-SCSpecimen collection is where most results are won or lost: an assay run flawlessly on the wrong tube, the wrong patient or a clotted sample is still a wrong result. This domain covers everything that happens before testing begins — instructing collectors, questioning the order, confirming identity, drawing the blood, judging the specimen's condition, recording it, and getting it to the bench in time. Roughly fifteen percent of the field's questions sit in this area, and they reward practical judgement far more than recall. Specimen Collection is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.

Preparation and Testing
HEM-PTPreparation and testing covers everything a technologist does between accepting a specimen and generating a result someone can act on: confirming identity at each handover, preparing reagents and controls, spreading and staining films, driving the analyser, and reading what is actually on the glass. Much of the work is manual craft — a badly spread film or an over-buffered stain destroys morphology no instrument can recover. It also covers knowing where each method stops being reliable, because interference that goes unrecognised becomes a released result. Preparation and Testing is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.
15 subdivisions →
Evaluation and Interpretation
HEM-EIEvaluation and interpretation is where numbers and morphology turn into a decision. This domain covers judging whether a result is even possible, whether an abnormality belongs to the patient or to the specimen, what a set of haematology results means when read together, and when a finding must be confirmed, corrected or escalated before it leaves the laboratory. It is the judgement layer that sits between a validated instrument and a released report. Evaluation and Interpretation is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.

Reporting and Communication
HEM-RCThis domain covers everything that happens to a haematology result after the analyser stops counting: how it is documented, how it is released, who is told and how quickly, and what is written down when something goes wrong. It also covers the specimens and films that must leave your hands — sent to a reference centre, or put in front of a pathologist while the finding still matters. A technically perfect count that is badly reported, quietly lost, or never escalated does the patient no good at all. Reporting and Communication is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.
7 subdivisions →
Equipment and Resources
HEM-ERHaematology runs on instruments that the people at the bench must start up, calibrate, maintain and rescue when they misbehave. This domain covers routine operation and preventive maintenance of cell counters, coagulation analysers, centrifuges and microscopes, together with the structured troubleshooting that separates an instrument fault from a genuine patient result. It also covers the capture of digital images that are clear enough, and identified well enough, to stand as part of the laboratory record. Equipment and Resources is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.

Safety
HEM-SASafety in haematology is mostly about blood — uncapping it, spinning it, spilling it and shipping it. This domain covers the barriers you wear at the bench, the hygiene that keeps contamination from travelling, the rules for moving specimens between sites, and what a technologist does when something in the department is plainly not safe. The items below work through decisions that come up on an ordinary shift. Safety is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.
5 subdivisions →
Professionalism
HEM-PRThe haematology bench generates some of the most revealing information in the laboratory — a differential can announce a leukaemia before anyone has spoken to the patient — so the conduct wrapped around the technical work matters as much as the technique. This domain covers guarding that information, shaping a shift so time-critical specimens are not lost to poor sequencing, and treating the person attached to the tube as a partner rather than a source. Items here are written as small, ordinary decisions with one defensible action. Professionalism is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.
3 subdivisions →
Quality Assurance
HEM-QAQuality assurance is the work that lets a haematology result be defended after it leaves the bench: external surveys that compare the laboratory against its peers, control and calibration data read against a defined rule set, stain quality checked before any morphology is called, and procedures that are current and authorised. It is a small share of the exam but it touches every other domain, because a beautifully performed count reported off an out-of-control run is still a wrong result. Expect scenarios that ask what to do next rather than what a term means. Quality Assurance is one of the eight competency areas assessed in the Hematology Fields-of-Practice examination set by CAMLPR.
