Wimpole Street, Marylebone
Within the genetic testing range at Wimpole Street, the HLA DQ Alpha Antigens is the test to consider when the question concerns human Leukocyte Antigens, immune System and tissue Typing. It costs £369, and once the Marylebone clinic opens on 1 October 2026 a nurse or phlebotomist takes the venous blood sample (EDTA), with the laboratory typically reporting in 2 weeks, Send Mon-Tuesday only. Medical services are for patients aged 16 and over, self-referral with no GP referral needed, and the laboratory report is delivered to your secure portal.

Who considers HLA DQ Alpha Antigens
- People often consider genetic testing if several relatives have had the same cancer, especially breast, ovarian, bowel or prostate cancer at a young age.
- Couples planning a family may seek carrier screening for conditions such as cystic fibrosis, spinal muscular atrophy or Tay-Sachs, particularly where ancestry raises the likelihood.
- Those with a personal or family history of heart muscle disease, sudden death or very high cholesterol frequently ask about cardiac and lipid gene panels.
- Unexplained neurological, developmental or metabolic symptoms sometimes lead a specialist to recommend a targeted panel.
- Anyone about to start a medicine with known genetic variability in response, such as clopidogrel or certain antidepressants, may check a pharmacogenomic profile.
What HLA DQ Alpha Antigens measures
Laboratories file the HLA DQ Alpha Antigens under human Leukocyte Antigens, immune System and tissue Typing. The following sections set out how a genetic testing test of this kind is measured and read.
Genetic tests read DNA to look for variants associated with inherited conditions, cancer predisposition, carrier status or drug response. Approaches range from single-gene sequencing and targeted variant checks (HFE for haemochromatosis, MTHFR, Factor V Leiden) through next-generation sequencing panels covering dozens of genes linked to a condition, to chromosome analysis, array CGH and whole genome sequencing. Pharmacogenomic tests such as CYP2C19 predict how you metabolise particular medicines, and HLA typing identifies immune-system genes relevant to autoimmune disease, drug hypersensitivity and transplantation.
Preparing for your HLA DQ Alpha Antigens
- 1A pre-test discussion is recommended: results can have implications for relatives, insurance and future planning, and it helps to think these through before sampling.
- 2Some panels require written informed consent, which the nurse will go through with you; bring details of the family history including which relatives were affected and at what age.
- 3No fasting is needed; most tests use an EDTA blood sample, and a few use a cheek swab.
- 4Allow for a longer turnaround than routine bloods — panels and whole genome sequencing can take many weeks.
Sample for this test: venous blood sample (EDTA).
Understanding your HLA DQ Alpha Antigens results
A pathogenic or likely pathogenic variant can indicate a raised risk of the associated condition, but for most genes it does not mean the condition is certain, and the level of risk varies widely. Variants of uncertain significance are common on larger panels and are reported as findings whose meaning is not yet known; they should not be acted upon alone. A negative result reduces but does not eliminate risk, since not every relevant gene or variant is covered, and family history still counts.
Genetic results are probabilistic, have implications for relatives and can affect insurance under the UK Code on Genetic Testing; discussion with a genetic counsellor or specialist before and after testing is strongly advised.
