Genetic analysis of single nucleotide variants (SNVs) in serum/plasma using a probe-based assay for specific DNA sequences (e.g., associated with hereditary conditions)
This test checks for specific genetic changes in a blood sample that may be linked to inherited conditions, such as certain cancers, metabolic disorders, or muscle diseases.
["It helps identify if you carry genetic mutations that could affect your health or risk for inherited disorders."]

What This Test Measures
This test analyzes DNA from your blood sample to detect specific single nucleotide variants (SNVs) using a probe-based method. It looks for mutations in genes that may be associated with hereditary conditions, though not all genetic variants are tested for in this specific panel.
How the Test Works
Your blood sample is processed to extract DNA, which is then tested using a specialized probe that binds to sequences of interest. The presence of these genetic variants is identified through the assay’s detection system.
Why It Might Be Ordered
Your healthcare provider may recommend this test if you have a family history of certain genetic disorders, symptoms suggestive of an inherited condition, or if you are at higher risk due to genetic testing guidelines.
What to Expect Before the Test
No special preparation is needed for this test. You may have a simple blood draw, similar to other routine blood tests. If you are taking blood thinners, inform your provider beforehand.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Short name
Hereditary DNA variant screening (serum/plasma)
