SPECIALISED PATHOLOGY SERVICES
Haematology Laboratory Services
Understand the blood cells that carry oxygen, protect you and help clotting.
Haematology looks at blood cells and some parts of the clotting system. A complete blood count (CBC), for example, reports several measurements involving red cells, white cells and platelets. The figures may help investigate anaemia, inflammation and other concerns, but the pattern needs medical interpretation.
Typical sample: blood CBC is a common first test Clotting tests are separate investigations
UNDERSTANDING THE PURPOSE
Why this may be useful

BEFORE YOU VISIT
How to prepare
Many blood counts need no fasting, but other tests ordered with them may.
Tell your doctor if you take blood-thinning medication.
Do not change anticoagulant doses without medical advice.
Understanding the next step
A blood count outside the reference range may have several explanations, including normal variation. A clinician may recommend a repeat sample or specific follow-up investigations.
