Carcinoembryonic Antigen (CEA) is a tumour marker measured in blood to help detect or monitor certain cancers. CEA levels may assist in monitoring known malignancies but are not reliable for early diagnosis, as markers may be normal in early stage disease.

Clinical Details
High CEA
A raised CEA level can be associated with certain cancers—particularly gastrointestinal malignancies—note thattumour markers lack specificity, meaning elevated CEA can also occur in benign conditions and is not diagnostic of cancer. High CEA is most useful in monitoring patients with known malignancy rather than detecting disease.
Low or Normal CEA
A normal or low CEA level does not rule out cancer, as tumour markers may be normal in early-stage disease or in some patients even with advanced malignancy. Note that tumour markers have limited sensitivity, so low values cannot exclude malignancy

Patient
Request Form
For clients using the Enfer Medical Client Portal, the Enfer Medical Patient Request Form (PRF) will be generated when you have completed your “Test Request” within the portal linked below.
Please note that samples suspected of containing high risk pathogens such as Mycobacterium tuberculosis should be clearly identified on the form and packed separately from other samples.
24 hours
Results are available next working day.
7 Days a Week
This assay is available seven days a week.
Packaging
The packaging/preparation of samples for delivery to the laboratory are required to be in adherence to all national regulations for the safe transport of biological materials. HSE guidance can be reviewed HERE.
There are specific packaging instructions and labelling requirements requiring triple packaging including:
- Primary leak-proof container – tube or vial containing the sample.
- Secondary watertight container, with absorbent material, intended to protect the primary container.
- Outer container protects the secondary container.
- Patient Request forms must be placed between the secondary container and the outer shipping container.
Further information on the packaging/preparation of samples for delivery to the laboratory is contained within the Enfer Medical Laboratory User Manual which clients are provided with.
Storage & Stability
Specimens must be tested within 7 days of collection and stored at 2-8°C.
Transporting
Samples
Samples
In addition to the packaging of samples, the transport/delivery of clinical samples to the laboratory is required to be in adherence to all national regulations for the safe transport of biological materials. Enfer Medical provides a fully compliant logistics service, aligned with clients’ testing requirements.
Prompt transport of specimens:
To ensure prompt testing of samples and release of results within the published test turnaround times, samples should arrive to the laboratory by 18:00. Test turnaround time is measured from receipt of the sample at the laboratory until the time the authorised results are reported to users.
Acceptance/Rejection
of Samples
of Samples
In rare cases specimens may not be suitable for testing on arrival to the laboratory. In that case the sample will be rejected at the receipt stage and the service user will be notified immediately and an explanation as to why the sample could not be processed will be provided. Reasons why samples cannot be processed include but are not limited to:
- Samples received beyond the stability limits and/or not at the correct temperature indicated for each test.
- Incorrect sample type received.
- Leaking samples, sample not received or sample insufficient for analysis as stated below within sample requirements.
- Non-compliant samples or request forms i.e. those missing sample date information, missing sample test request and/or missing sample site/type information.
- Samples received without the necessary patient identifiers.
Clients will be provided with guidance on Sample Receipt Anomalies.
