Encephalopathy high dose lead

E. Other tests. Nonspecific laboratory findings that support the diagnosis of lead poisoning include anemia (normocytic or microcytic), and basophilic stippling of erythrocytes, a useful but insensitive clue. Acute high-dose exposure may sometimes be associated with transient azotemia (elevated BUN and serum creatinine) and mild to moderate elevation in serum transaminases. Recently ingested lead paint, glazes, chips, or solid lead objects may be visible on abdominal x-rays. CT or MRI of the brain often reveals cerebral edema in patients with lead encephalopathy. Because iron deficiency increases lead absorption, iron status should be evaluated.
