A) Capillary screens are generally reliable, but do carry the risk of contamination, and thus should be confirmed with whole blood lead levels.
B) Current federal Medicaid guidelines require lead screening in children at 12 and 24 months of age. In addition, lead screening is required in all children between the ages of 36 to 72 months who previously have not been screened for lead.
C) Refugee children are at higher risk, and the CDC recommends lead testing in all refugee children from the age of 6 months to 16 years upon entry to the United States. Repeat lead testing is recommended in children ages 6 months to 6 years after 6 months in a permanent residence. Other residents should be tested if a blood lead level comes back elevated.
D) In children with blood lead levels between 20 to 44 mcg/dL, obtain a hemoglobin or hematocrit level and evaluate the child's iron status. Consider abdominal radiographs with bowel decontamination if particulate lead ingestion is suspected.
E) Zinc protoporphyrin and erythrocyte protoporphyrin assays are not sensitive at lower BLLs. In addition, they are not specific to lead, and have a lag time of approximately 120 days before showing effects of an exposure.
F) Hypochromia and basophilic stippling suggest lead intoxication, but they are nonspecific and their absence does not rule out the diagnosis.
G) Employees whose blood lead level is equal to or greater than 50 mcg/dL should be temporarily removed from exposure until their blood lead level is at 40 mcg/dL or below.
