The Folate Receptor Autoantibody Test, also known as the FRAT® test, is a specialised blood test that detects autoantibodies against the folate receptor alpha, also known as FRα.
Folate, or vitamin B9, plays an important role in cell growth, neurological function, and development. The folate receptor alpha helps transport folate into certain areas of the body, including the brain and nervous system. When autoantibodies are present, they may interfere with this transport process.
FRAT® testing can provide useful information for individuals, families, and health practitioners seeking a clearer understanding of folate receptor autoantibody activity.
What Does the FRAT® Test Measure?
The FRAT® test detects two types of folate receptor alpha autoantibodies:
- Blocking autoantibodies, which may interfere with folate binding
- Binding autoantibodies, which may affect folate receptor function
These autoantibodies may disrupt how folate is transported, even when standard blood folate levels appear within range. For this reason, FRAT® testing may be considered as part of a broader clinical investigation when recommended by a qualified health practitioner.
Why Folate Transport Matters
Folate is involved in several important biological processes, including DNA synthesis, methylation, red blood cell production, and nervous system function.
When folate transport is affected, it may be relevant to discussions around neurological, developmental, or related clinical concerns. The FRAT® test does not diagnose a condition by itself. Instead, it provides laboratory information that may assist a health practitioner when reviewing symptoms, history, and other test results.
Who May Consider FRAT® Testing?
FRAT® testing may be considered by individuals or families who have been advised by a health practitioner to investigate folate receptor autoantibodies.
It may be relevant in discussions involving:
- Folate transport
- Neurological development
- Nervous system function
- Methylation pathways
- Clinical investigation into folate-related concerns
- Specialist practitioner review
Any decision to order or interpret this test should be made with guidance from a qualified healthcare professional.
What Is Involved in the Testing Process?
FRAT® testing is completed using a blood sample. Once the sample is collected, it is sent for laboratory analysis to assess whether folate receptor alpha autoantibodies are present.
Results should be reviewed with a qualified health practitioner, who can explain what the findings may mean in the context of medical history, symptoms, and any other relevant testing.
