What is this test?
This test measures the amount of DOCK8 protein in monocytes. Monocytes are a type of white blood cell that help your body fight infections and are part of your immune system. DOCK8 is a special protein that helps these immune cells work properly. The test uses flow cytometry, which is a laboratory technique that can identify and count different types of cells based on specific markers on their surface.
How is the test done?
A healthcare provider will draw a small sample of blood from your arm. This blood sample is then sent to a laboratory where special machines analyze the cells. The test looks at monocytes (identified by CD14 marker) and measures how much DOCK8 protein they contain. The results are expressed as a ratio comparing DOCK8-positive cells to total monocytes.
Why might I need this test?
Your doctor may order this test to check how your immune system is working. It can help diagnose or monitor conditions that affect the immune system. The test may also be used to understand certain heart-related conditions, as immune cells can play a role in cardiovascular health.
Reference range
Reference range: 85-95% of CD3-CD14+CD45+ cells express DOCK8. Reference values may vary by laboratory methodology and instrument. Clinical correlation recommended.N/A
No special preparation required. Patient does not need to fast. Inform the laboratory of any recent infections, immunosuppressive therapy, or bone marrow transplantation as these may affect results.
Clinical interpretation
