Genetic Testing vs. Genomic Testing: Understanding the Differences in Medical Laboratories

Summary

• Patient population with a strong family history of genetic diseases or cancer may benefit most from Genetic Testing.
• Patient population with complex, chronic, or rare diseases may benefit most from genomic testing.
• Genetic Testing focuses on specific genes, while genomic testing looks at an individual's entire genetic makeup.

Genetic Testing vs. Genomic Testing: Understanding the Differences

Genetic Testing and genomic testing are two types of tests that are commonly used in medical laboratories in the United States. While both tests involve analyzing a patient's DNA to identify genetic abnormalities, they serve different purposes and are used for different patient populations.

Genetic Testing

Genetic Testing is a type of test that focuses on examining specific genes or chromosomes to identify mutations or variations that may be causing a particular disease or condition. This type of testing is often used to diagnose genetic disorders, determine a person's risk of developing a hereditary disease, or guide personalized treatment plans.

1. Patients with a strong family history of genetic diseases or cancer may benefit most from Genetic Testing.
2. Genetic Testing can help individuals understand their risk of passing on a genetic condition to their children.
3. Genetic Testing can also be used to identify the best treatment options for certain genetic conditions.

Genomic Testing

Genomic testing, on the other hand, looks at an individual's entire genetic makeup, including both coding and non-coding regions of the genome. This type of testing provides a more comprehensive analysis of a patient's genetic information and can identify variations that may be associated with complex, chronic, or rare diseases.

1. Patient population with complex, chronic, or rare diseases may benefit most from genomic testing.
2. Genomic testing can help identify the underlying genetic causes of a disease that may not be detected by Genetic Testing.
3. Genomic testing can also provide information on how a patient may respond to certain medications or treatments based on their genetic makeup.

Which Patients Would Benefit Most from Genetic Testing?

Patients who are considering Genetic Testing should talk to their healthcare provider or a genetic counselor to determine if testing is right for them. Some patient populations that may benefit most from Genetic Testing include:

1. Patients with a family history of a genetic disease or condition.
2. Patients with a personal or family history of certain types of cancer.
3. Patients who are planning to start a family and want to understand their risk of passing on a genetic condition to their children.

Which Patients Would Benefit Most from Genomic Testing?

Genomic testing is typically recommended for patients who have complex, chronic, or rare diseases that may be caused by multiple genetic factors. Some patient populations that may benefit most from genomic testing include:

1. Patients with undiagnosed or rare genetic disorders.
2. Patients with complex diseases that have not responded to traditional treatments.
3. Patients who are interested in Personalized Medicine and want to understand how their genetic makeup may impact their health and treatment outcomes.

Conclusion

Both Genetic Testing and genomic testing play important roles in medical laboratories in the United States. While Genetic Testing is focused on specific genes and is often used to diagnose hereditary conditions, genomic testing provides a more comprehensive analysis of an individual's genetic makeup and can help identify the underlying causes of complex diseases. Patients who are considering genetic or genomic testing should consult with their healthcare provider to determine which type of testing is right for them based on their medical history and health goals.
