Folate Receptor Autoantibody Test (FRAT) London – What It Is & Why It Matters

If you or your child is experiencing unexplained neurological, developmental, or fertility issues, a Folate Receptor Autoantibody Test (FRAT) could provide some answers.

At Marylebone Diagnostic Centre, we offer specialised FRAT testing in London to detect hidden immune reactions that can block folate from reaching the brain and cells.

What Is a FRAT Test?

The Folate Receptor Autoantibody Test (FRAT) is a blood test that detects autoantibodies against folate receptors.

These receptors are essential because they help transport folate (vitamin B9) into:

• The brain
• The placenta
• Cells throughout the body

When autoantibodies block these receptors, the body may experience functional folate deficiency, even when folate levels appear normal.

Why Is This Important?

Folate plays a key role in:

• Brain development
• DNA synthesis
• Pregnancy health
• Neurotransmitter function

When folate cannot reach cells properly, it may contribute to:

• Developmental delays
• Autism spectrum conditions
• Cognitive issues
• Fertility problems
• Pregnancy complications

Who Should Consider a FRAT Test?

This test is particularly important for:

1. Children with Developmental Concerns

Including:

• Autism spectrum disorder (ASD)
• Speech delay
• Learning difficulties

2. Couples Facing Fertility Issues

Folate is critical for:

• Egg quality
• Sperm health
• Early embryo development

3. Patients with Neurological Symptoms

Such as:

• Brain fog
• Memory issues
• Unexplained fatigue
• Mood disorders

4. Women with Pregnancy Complications

Including:

• Recurrent miscarriage
• Neural tube defect risk
• Unexplained infertility

How Does the FRAT Test Work?

The test identifies two key types of antibodies:

• Blocking antibodies – prevent folate from binding to receptors
• Binding antibodies – interfere with receptor function

Both can reduce folate delivery to critical tissues, especially the brain.

FRAT Test vs Standard Folate Blood Test

This is why many patients remain undiagnosed without FRAT testing.

What Happens After a Positive Result?

If FRAT antibodies are detected, management may include:

• High-dose folinic acid (not standard folic acid)
• Targeted supplementation
• Clinical monitoring

This approach helps bypass blocked receptors and restore folate delivery.

Why Early Testing Matters

Early detection can:

• Improve neurological outcomes in children
• Support fertility and pregnancy success
• Reduce long-term complications
• Provide clarity for unexplained symptoms
