| Hearing risk assessment | do at all health maintenance visits, and periodic hearing screening between ages 4 and 10 years of age. |
| When should vision be assessed? | recommended screening to detect amblyopia, strabismus and defects in visual acuity in children younger than 5 years of age. AAP/bright futures suggests at 3-4 years of age. >5 at all health maintenance visits |
| Autism screening | at 18 and 24 months of age |

| Iron deficiency screening | once between 9-12 months and 15-18 months. Annually thereafter until age 5. |
| Neonates testing | newborn screen, blood type and screen/DAT (from cord blood usually), bilirubin, glucose, TORCH, HgB |
| Ideal timing of newborn screen | between 24-72 hours post birth. Ideally after baby is 1 day old. PKU will be false negative if done <24 hours and must be repeated in 7 days |
| Information to include on heel stick filter paper | date, time, feeding source on requisition. In NC, you need to mail this to State Laboratory of Public Health w/in 24 hours |

| Cord blood and DAT are used to diagnose | Hemolytic dz of the newborn. Infants <4 months old rarely make red cell alloantibodies |
| what assesses for kernicterus in neonates? | bilirubin levels. Kernicterus is aka bilirubin encephalopathy. Bilirubin reference ranges vary depending on preterm vs term, but M=F |

| Which site is used to collect a blood specimen for lead levels? | fingertip capillary specimen. MUST BE A VENOUS SPECIMEN. PUT IN TUBE WITH ROYAL BLUE TOP: EDTA TUBE. If capillary screen is +, must be f/u with venous confirmation |
| Lead level 10-19ug/dL | venous diagnostic test within 3 months. retest Q 2-3 months until 3 consecutive levels<10 |
| Lead level 20-44ug/dL | venous diagnostic test w/in 1 week. If +, refer for medical evaluation and environmental investigation |
| Lead level >/=45ug/dL | venous diagnostic test ASAP. If +, chelation |
| TB testing is appropriate in | all children at HIGH RISK for TB. TST is the only recommended screening test. Can begin TST>/= 3 months. Repeat annually if TB risk persists |
