FRAT® (Folate Receptor Autoantibody Test) measures the presence of autoantibodies against the folate receptor alpha (FRa) protein. Folate receptor autoantibodies can interfere with folate (vitamin B9) transport into the brain, potentially leading to neurological symptoms and developmental delays.

If FRAT® detects autoantibodies, a healthcare professional can discuss treatment options. This may involve using alternative folate forms that bypass the blocked transport system or making dietary adjustments. Please consult your physician for information and guidance.
