Standard lead blood tests cost between $50 and $100, and this fee varies widely based on your insurance. Call your doctor or health department to arrange a blood test and ask about pricing for your family's policy. If tests reveal lower levels in children, 5 micrograms (mcg) per deciliter (dl), request a risk assessment. Assessors will create a strategy to remove the source of the poisoning and avoid further exposure. Severe cases of 45 mcg/dl or higher require additional medical treatments through chemical injection or expelling it from your system.
