title: Direct-to-consumer DNA testing and the GP.
abstract: BACKGROUND
  From early 2000 a new form of DNA genetic testing became available commercially. It bypasses the medical practitioner and can be ordered directly by the individual.
  
  
  OBJECTIVE
  To understand direct-to-consumer (DTC) DNA genetic testing and be able to respond appropriately if asked to be involved by a patient.
  
  
  CONCLUSIONS
  Presently, all but one or two DTC DNA genetic testing laboratories are located outside Australia. The industry promotes itself as a means to better health through giving individuals complete control over their results. When communicating with patients about DTC DNA genetic testing, general practitioners will need to make a determination about the clinical utility of the test and the laboratory validity, both of which can be difficult in the current environment. Assistance may be available through public hospital clinical genetics services, although waiting times can be long. There is likely to be tighter regulation of these types of testing in the future, which may include involvement of medical practitioners.
