Haemoglobinopathy genetics: For UCLH requests, it is mandatory to include informed consent for DNA testing and storage, otherwise a request cannot be made. Referrers outside UCLH use the Haemoglobinopathy request forms: Prenatal Diagnosis request form or Haemoglobinopathy Genotype request form.

Haemophilia and thrombophilia genetics: Requests for Haemophilia and Thrombosis Molecular Genetics must be accompanied by a request form.

For users on the Royal Free network, the form is available on Freenet (http://freenet/freenetcms/Default. aspx?&s=38&p=860&m=1778). For other users, please contact the the laboratory for a form.

Essential information on sample container label:

Consent forms

Consent forms are available for genetic testing. As genetic testing may have implications for other family members and is regarded as personal data, it is recommended that written consent is obtained wherever possible. In cases with predictive testing for severe disorders, as indicated in the laboratory guide, it is essential that patients should also be offered formal genetic counselling.

It is the responsibility of the referring clinician to obtain appropriate consent from the patient.


Clinical Details

Clinical details are very important when providing genetic analysis. The more clinical information that is available (e.g. details of ultrasound information, phenotypic features or family history) the better the service we can provide. Failure to provide this information for genetic studies may result in an inaccurate analysis or interpretation.
