MICA · CARE LEARNING NOTES
Observe, keep care safe and communicate
Specimen quality begins before puncture and continues through to the laboratory. Identity, collection conditions, labelling and transport determine result reliability as much as the procedure itself.
Link patient, request and tubes
Compare patient identity with the test request and apply the institutional identification procedure. When the person can answer, asking them to state their identity is safer than offering a name to confirm. Check the tests actually requested and their collection requirements with the laboratory. A technically well-collected tube assigned to the wrong person creates dangerous information for clinical decisions.
[1][2]Anticipate preanalytical errors
Tube type, filling, handling and transport requirements depend on tests and equipment. Refer to laboratory instructions rather than cap colour alone. Report a difficult collection or possible contamination by infused fluid. Haemolysis can alter results; it must not lead to reassuring or alarming interpretation without considering the clinical context.
[1]Protect patient and professional
A trained, authorised person collects blood using standard precautions and appropriate equipment. Prevent fainting-related harm by asking about previous episodes and ensuring safe positioning. Monitor unusual pain, haematoma or persistent bleeding. Dispose of a used sharp immediately in the designated container. Any accidental blood exposure must be reported promptly for institutional assessment and management.
[1][3]Prepare tubes and confirm identity with the patient before sampling. Labelling must unambiguously identify the person sampled, at the point of care, under the local procedure. After withdrawing equipment, check haemostasis, especially during anticoagulation, and dispose of sharps immediately without recapping.
- Never correct uncertain identity by guessing; follow the non-conformity procedure.
Maintain an identifiable chain
Label close to collection according to the validated procedure, keeping patient, tubes and request aligned. Document special conditions and timing when they influence testing. Identity uncertainty must not be corrected from memory afterwards: contact the laboratory and follow the nonconformity procedure. Arrange appropriate transport and report any difficulty so the team can decide on acceptability or recollection.
[1][2]A learning situation
FICTIONAL SITUATION · REFLECTION WITHOUT A SCORE
Fictional situation: after two consecutive collections, an unlabelled tube remains on the trolley. The professional thinks the patient can be identified from the order of care.
Can the label be completed from memory?
Read the reasoning
No. The order of care does not establish specimen identity. Set the tube aside, notify the laboratory and follow the nonconformity procedure; recollection may be required according to the appropriate decision. Record the event and identify the organisational contributing factor. Misattribution can lead to unnecessary treatment or conceal a real emergency.
