Lynch syndrome is caused by a genetic abnormality that can now  be easily detected via a genetic panel. These tests can be ordered through a physicians or now direct to consumer. While genetic testing 10 years ago cost up to $6,000, it is now available for under $300. The test can be performed with a mouth swab or with a blood sample.

Lynch syndrome is associated with abnormalities in one of five genes. These are MLH1, MSH2, MSH6, PMS2, and EPCAM. The cancer risks are slightly different depending on which gene is affected.

Because of the multiple risk factors associated with Lynch syndrome, it is important to have either a qualified physician or a genetic counselor help with testing and proper followup.

Color Genomics offers a comprehensive genetic panel for $299 that includes Lynch syndrome along with other cancers and health risks. It offers direct to consumer or through a physician's office. Invitae and Myriad Genetics are two other excellent labs that offer testing through physician's offices. They routinely bill insurance companies but also offer a "cash price" that will reduce the patient cost to just $250. If cost is an issue requesting that at the time of ordering is best.
