Genetic Services



As well as providing the following genetic services, GENASSIST is a unique company in that they provide coordination for any and all genetic services that a patient may need. GENASSIST uses a network of laboratories which are able to provide prompt, accurate services which each patient deserves. This unique approach, saves the patient time and money, while providing ongoing support during an uncertain time.

The wide breadth of work in genetics makes compilation and use of the emerging information by any single specialty difficult. With the rapid pace of progress in genetics, advancements introduced in one area may not see introduction into other specialties for several years. GENASSIST through specialty labs throughout the country, attempts to shorten the lag between the development of newer approaches to medical problems and their applications to families at risk. Also, approaches that appear to have promise for the future and those that currently offer diagnostic and therapeutic options for families and health care providers can be explored.

The ultrasound department is certified by The American Institute of Ultrasound in Medicine (AIUM) and Aneuploidy Certification by The Fetal Medicine Foundation and NTQR.

GENASSIST's 30 year commitment to zero defects, fastest turnaround times, and user-friendly atmosphere for both patients and their health care providers has made it an example for other programs to strive for, and has helped put Denver high on the genetic map, both nationally and internationally.

As more people become aware of the role that genetics plays in their personal lives, such as the possibility of a patient or a patient's family member developing certain medical conditions, the need for accurate, cost-effect and timely genetic services will grow.
