Testing Schedule for Fels Participants
New Fels Study participants are enrolled into the study at birth and are seen five times during the first year and then twice a year until age 5 and once a year to age 8 years. Starting at age 9 years, Fels children begin visits every 6 months. This schedule continues until 18 years of age, at which time the half-year visits are dropped and participants come in yearly through age 20. Beginning at age 21 years, adult participants come in every two to five years depending upon where they live. Thank you to all Fels Participants for your dedication and time to this very important study!
