Spinal Muscular Atrophy (SMA) Carrier Test is a laboratory test you can request directly. The Spinal Muscular Atrophy (SMA) Carrier Test checks if someone carries a gene linked to SMA.
What this test is
The SMA Carrier Test is a blood test used to identify if a person carries a genetic mutation associated with spinal muscular atrophy. SMA is a genetic condition that affects motor neurons, leading to muscle weakness. Being a carrier means having one copy of the mutated gene but not showing symptoms.
What it measures
- SMN1 gene — reflects carrier status for SMA
What the test involves
The test involves a standard blood draw, typically from a vein in the arm. The sample is then analyzed for specific genetic markers related to SMA.
Why it is often ordered
Clinicians may order this test to assess carrier status, especially if there's a family history of SMA. It can also be part of prenatal testing to evaluate potential genetic risks.
Preparation
Preparation for the SMA Carrier Test may involve specific instructions from the lab. Always follow the lab's guidelines for accurate results.
How results are reported
