Spinal Muscular Atrophy (SMA) Carrier Test Profile – Port Huron, MI
Below is a plain-language overview of the spinal muscular atrophy (sma) carrier test in Port Huron, MI. This test analyzes your genes to see if you carry a change that could cause spinal muscular atrophy (SMA). It is used for family planning and prenatal testing.
What this test is
The Spinal Muscular Atrophy (SMA) Carrier Test is a genetic test that looks for specific changes in the SMN1 gene. These changes are associated with an increased risk of having a child with SMA.
What it measures
- SMN1 Gene Copy Number — Reflects the number of copies of a gene critical for motor neuron survival
What the test involves
This test is performed on a sample of your blood. A healthcare professional will collect the blood sample using a standard blood draw procedure.
Why it is often ordered
Clinicians often order this test for individuals or couples planning a family, especially if there is a known family history of SMA. It helps assess the likelihood of passing on the genetic changes associated with the condition.
Preparation
No special preparation is usually needed for this test. You should follow any specific instructions provided by the laboratory that will perform the test.
How results are reported
Results typically indicate whether one or more copies of the SMN1 gene are present. Reference ranges and interpretation of results can vary between laboratories.

FAQ
Frequently asked questions
What is spinal muscular atrophy (SMA)?
SMA is a rare genetic disorder that affects nerve cells in the spinal cord, leading to muscle weakness and wasting. The severity of SMA can vary widely.
What does it mean to be a carrier for SMA?
Being a carrier means you have one copy of the SMN1 gene with a change that causes SMA, but you typically do not have symptoms yourself. However, you could pass this gene change to your child.
Can this test be done during pregnancy?
Yes, this test can be used for prenatal diagnosis. It can help determine if a fetus has inherited the genetic changes associated with SMA.
How accurate is the SMA carrier test?
This test is highly accurate at detecting common genetic changes in the SMN1 gene. However, very rare changes may not be detected.
