Child Health and Disability Prevention Program
CHDP provides well-child physicals for children through 21 years of age at the county level, using a combination of federal and state funds. The complete examination includes hearing, vision, lead level, anemia check, urinalysis and immunizations. If Medi-Cal eligible, services extend to age 21. Other sources of these services include local public education agencies, private pre-schools, public daycare, and Headstart.
