Overview of the CD56 Blood Test
The CD56 Blood Test measures CD56, a surface marker found primarily on natural killer (NK) cells, an important type of white blood cell involved in the body's innate immune response. Natural killer cells help identify and destroy virus-infected cells and abnormal cells while contributing to overall immune surveillance.
This is a single-biomarker immunology test that measures CD56. The test is commonly requested as part of specialist immune system assessments, immunophenotyping investigations or when evaluating natural killer cell populations under the guidance of an immunologist or other healthcare professional.
People may choose this test to investigate immune function, monitor known immune-related conditions, support specialist investigations or obtain additional laboratory information before consulting a GP, immunologist or other specialist. It may also be requested alongside other lymphocyte subset tests to provide a broader picture of immune cell populations.
Although CD56 provides valuable information about natural killer cells, it does not diagnose an immune disorder on its own. Results should always be interpreted alongside symptoms, medical history, medications, other laboratory findings and professional clinical assessment.
What Does the CD56 Blood Test Check?
CD56 - CD56 is a protein found on the surface of natural killer (NK) cells and a small proportion of T lymphocytes. Measuring CD56 helps assess the number or proportion of these immune cells, which play an important role in the body's first-line defence against infections and abnormal cells. The result contributes to specialist immune assessments and should always be interpreted alongside other clinical findings.

Laboratory analysis

When Will I Receive My Results?
Results are typically available 1 day after the laboratory receives your sample.
Once authorised by the laboratory, your report will be sent securely by email.
Turnaround times begin when the laboratory receives the sample rather than when it is collected. Specialist immunology testing may occasionally require additional processing time. Results outside the expected range should be reviewed with a GP, immunologist or other suitably qualified healthcare professional.
Understanding Your Results
Your report will include your CD56 result together with the laboratory reference information where appropriate.
Reference ranges and reporting methods may vary between laboratories due to differences in analytical techniques. A result within the reference range does not always exclude an underlying health condition, while an abnormal result does not automatically confirm a diagnosis.
Results should always be interpreted alongside symptoms, medical history, medications, age, other immune markers and relevant clinical information. If you have concerns regarding your results, speak with a GP, immunologist or other qualified healthcare professional.
