SCC Antigen Blood Test (Squamous Cell Carcinoma Marker)
Monitor squamous cell carcinoma with a single blood marker.
What’s tested
Pick a time
The SCC Antigen Blood Test measures squamous cell carcinoma antigen (SCC-Ag) in the bloodstream. This tumour marker is used alongside clinical assessment and imaging to support the monitoring of squamous cell carcinomas, including those affecting the cervix, head and neck, lung, oesophagus, and skin. It is not a screening test for the general population, but it can be valuable for tracking disease progression, treatment response, and possible recurrence in patients with a known diagnosis.
The test is performed on a simple blood sample using an immunoassay technique. Results are interpreted by your doctor in the context of your medical history, examination findings, and any imaging or biopsy results.
Biomarkers
- Squamous cell carcinoma antigen (SCC-Ag)
Why it matters
SCC-Ag can provide useful information about tumour activity and help your clinical team make informed decisions about ongoing care. Serial measurements over time are often more informative than a single result, allowing clinicians to observe trends that may indicate response to treatment or early signs of recurrence. If you have been diagnosed with a squamous cell carcinoma, this test can form part of a broader monitoring strategy tailored to your individual needs.
No special fasting required. Drink plenty of water prior to your appointment for a smooth blood draw.
- Identification: Photo ID (Passport or Driving Licence) is only required if you need your report for official, employment, visa/travel, premarital, or Identity-Verified Certificate (IVS) purposes (not required for personal health & wellness testing).
This test provides an official, quality-assured laboratory report with reference ranges. These results are for clinical information and do not replace your GP or consultant. Always discuss abnormal results with your GP or specialist in the context of your medical history.
