Limitations of the CD4 Counts Test
The accuracy of the CD4 Counts Test depends on proper sample collection and on the laboratory method used. A value outside the range is not a diagnosis on its own, so the CD4 Counts Test is best interpreted with a provider. A lymphocyte subset panel measures CD3, CD4, CD8, the CD4/CD8 ratio, CD16/56, and CD19 lymphocytes in the blood. No single test, including the CD4 Counts Test, can answer every question about your health.
How Often the CD4 Counts Test Is Repeated
A provider can advise whether the CD4 Counts Test should be repeated and how far apart the tests should be. Keeping prior CD4 Counts Test reports helps show trends rather than a single point in time. How often the CD4 Counts Test is repeated depends on why it was ordered and what your provider recommends. For routine monitoring, the CD4 Counts Test may be repeated at regular intervals to track the same markers over time.
High and Low CD4 Counts Test Results
A value above the range is called high and one below is called low, but either can have many explanations. High and low results from the CD4 Counts Test are best reviewed with a healthcare provider rather than interpreted alone. A lymphocyte subset panel measures CD3, CD4, CD8, the CD4/CD8 ratio, CD16/56, and CD19 lymphocytes in the blood. A single high or low value from the CD4 Counts Test may reflect normal variation, so repeat testing is sometimes used.
