Pharmacogenetic Screening (PGx)

Pharmacogenetics, also called pharmacogenomics, is the study of how genes affect the body’s response to certain medicines. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color. Your genes can also affect how safe and effective a particular drug could be for you.

Genes can be the reason the same medicine at the same dose will affect people in very different ways. Genes may also be the reason some people have bad reactions to a medication, while others have none.

Pharmacogenetic testing looks at specific genes to help figure out the types of medicines and dosages that may be right for you.

Right now, the most prevalent use of PGx testing comes from the field of behavioral medicine. Behavioral medications eligible for PGx testing include:

  • Antidepressants
  • Antipsychotics
  • Attention deficit disorder treatments

Other medications eligible for PGx testing include:

  • Opioids
  • Statins
  • Warfarin (blood thinner)
  • Plavix (blood thinner)
  • Tamoxifen (breast cancer)
  • Carbamazepine (epilepsy)
  • Abacavir (HIV)
  • Certain treatments for childhood leukemia
  • Certain treatments for autoimmune disorders

Lab 24 tests using a non-invasive buccal test. This is a simple saliva test in which the inside of the patient’s cheek is swabbed to recover skin cells. The swab is inserted into a plastic storage tube, which is placed in a plastic bag and sealed for delivery. The process is the same for both PGx and CGx tests, but each test requires a separate swab sample.
