Presymptomatic testing
Presymptomatic testing
The Human Genetics Society of Australasia (HGSA) has produced the HGSA
Guidelines for DNA Predictive Testing. In accordance with the HGSA
Guidelines:
- Presymptomatic (predictive) testing is offered for Myotonic dystrophy
(DM) and Spinocerebellar ataxia (SCA).
- All presymptomatic test requests must be accompanied with a signed
consent form. Presymptomatic testing cannot proceed without this consent
form.
- On receipt of the signed consent laboratory staff can proceed with the
knowledge that appropriate counselling has been provided.
- Any sample received for late onset disorders eg DM and SCA MUST have
CLINICAL indication for testing. In cases where NO clinical information is
provided, clarification will be sought to ascertain that it is not a
predictive test, causing a delay in test results.
- This is a Class B test and is subject
to testing under NPACC guidelines (2000).
