Genetic Mutation Screening in Whole Blood via Next-Generation Sequencing

What This Test Measures

The test analyzes DNA extracted from your whole blood sample to detect known mutations in genes associated with certain hereditary disorders. It focuses on a selected panel of genes, often linked to conditions like cancer predisposition, metabolic disorders, or neurological diseases. The results identify whether you carry specific mutations that may influence your health risks.

How the Test Works

Your blood sample is processed to isolate DNA. Advanced sequencing technology reads the genetic code to compare your DNA sequence against a database of known mutations. This process can detect small changes (mutations) in your DNA that may not show up on traditional blood tests.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of certain genetic conditions, if you’re at higher risk due to ethnicity, or if symptoms suggest a genetic cause. It can also be part of prenatal or preconception testing for couples with a history of genetic disorders.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for a few hours if your blood is drawn during a fasting window. Bring any relevant medical history or family history of genetic conditions to your appointment.
