MICA · CARE LEARNING NOTES
Observe, keep care safe and communicate
A reliable laboratory result begins before analysis. Identity, patient preparation, the container and transport form a safety chain shared by the care team and the laboratory.
Connect the request to the patient
Compare the identity stated by the patient, institutional identifiers and the test request before collection. A room number is insufficient. Explain the purpose and process, protect privacy and identify difficulties understanding instructions. For a patient unable to communicate, follow the institution’s identification procedure; an assumed identity creates a direct risk of assigning a result to the wrong person.
[1][2]Check relevant conditions
Consult laboratory instructions for any fasting requirement, timing, treatment context, tube type and required volume. Requirements vary by test: fasting is not needed for every sample. Report treatment or circumstances that may affect interpretation without independently changing a prescription. For an unfamiliar or urgent test, contact the laboratory before collection.
[1][2]Label and transport
Label at collection according to the local procedure, checking agreement with the patient. Record the date, time and collector. Use a closed container and suitable packaging, protecting the request from contamination. Temperature, protection from light and transport time are test-specific; routinely refrigerating every sample can also compromise quality.
[2]The laboratory needs sample type, collection time and relevant transport conditions. Even a well-analysed sample is unusable if identity is uncertain. Report non-conformity before interpretation; never relabel from memory. Check temperature or timing requirements for the specific requested test.
- Confirm special conditions with the laboratory rather than applying them to every tube.
Manage nonconformity
For an unidentified tube, a discrepancy or a potentially contaminated sample, notify the laboratory and clinical lead. Do not correct identity from memory or assumption. Exceptional acceptance of an irreplaceable sample belongs to the laboratory’s documented process. Record the incident, arrange recollection if necessary and ensure the clinical emergency continues to receive care.
[1][2]A learning situation
FICTIONAL SITUATION · REFLECTION WITHOUT A SCORE
Fictional situation: a tube arrives with a readable label, but the date of birth differs from the request. The collector believes they remember the patient.
Can the label simply be reprinted?
Read the reasoning
No. Pause routine processing and contact the laboratory and the person responsible for care. Resolve identity through the nonconformity procedure without reconstructing it from memory. A correctly identified replacement sample may be necessary. Inform the prescriber if the delay affects an urgent decision and document the resolution.
