The Canavan disease carrier test is a blood test that checks whether a person carries a gene change linked to Canavan disease, a rare inherited condition affecting the brain. It is usually ordered by people planning a pregnancy or with a family history who want to learn their chance of passing the condition on.

What it measures

  • ASPA gene — The gene that, when changed, causes Canavan disease.
  • Known gene changes (mutations) — Specific changes in ASPA that are tested for.
  • Carrier status — Whether one changed copy of the gene is present.
  • Variant details — The exact change found, if any, and what it means.

Who it is for

This test is typically ordered by people with a family history of Canavan disease, or by couples in certain ethnic groups where the condition is more common. A doctor or genetic counselor usually arranges it.

Preparation

No fasting or special preparation is needed. A blood sample can be drawn at any time of day.

Results and what they mean

Results are reported as carrier or not a carrier, sometimes with the specific gene change listed. A clinician or genetic counselor interprets the result, since it can affect family planning. This is general information only and not medical advice; discuss your results with a qualified professional.

Frequently asked questions

What does it mean to be a carrier?

A carrier has one changed copy of the ASPA gene but usually has no symptoms. Two carriers can each pass the gene on, which is why testing may be offered to couples.

Do I need to fast before this test?

No. There is no fasting or timing requirement, so you can eat and drink normally before your blood draw.

How long do results take?

Results are typically available within 1 to 3 business days, though this can vary by lab.

Should my partner be tested too?

If you are a carrier, a clinician may suggest testing your partner to understand the chance of having an affected child. A genetic counselor can explain the options.
