The FRAT test (Folate Receptor Antibody Test) is a blood test that checks for antibodies that block your child’s ability to absorb folate, a critical nutrient for brain development and cellular function.
About 50% of autistic patients have autoantibodies to the folate receptor, making the incorporation of folate into the cells impossible. Folate is especially needed in brain cells for adequate function. Folinic acid (Leucovorin) enter the cell through a different mechanism, is converted to folate, and then folate metabolism can proceed normally. Multiple blinded placebo-controlled studies exist demonstrating benefit of folinic acid in this population.
If the test is positive through the FRAT test, we prescribe folinic acid (Leucovorin), a medical-grade supplement that bypasses the blocked pathway and helps restore normal brain chemistry. It’s often used in combination with stem cell therapy to enhance cognitive and behavioral outcomes.
If parents would like to have this test performed, we provide a physician order to the parents to purchase the test online.
Once ordered, the kit will be shipped to your home. Bring the kit with you on the day of the stem cell procedure — we can draw the blood sample at the same time, making the process easier for your child.
