Limitations
- ⚠This test is not a standalone diagnostic tool; results must be interpreted with clinical history, morphology and other investigations.
- ⚠Absence of abnormal population does not completely exclude disease if sampling is inadequate.
Risks & Considerations
- ●Mild pain or bruising at the venipuncture site
- ●Bone marrow aspiration may cause transient discomfort
Interfering Factors
- ●Incorrect sample storage by refrigeration or freezing
- ●Delayed sample transport beyond recommended time
- ●Clotted or haemolysed sample
