Blood lead testing measures the amount of lead in your blood. Lead is a toxic heavy metal that can accumulate in the body and cause damage to the brain, kidneys, and nervous system. Exposure sources include lead paint in older homes, contaminated water, certain occupations (construction, battery manufacturing), and imported products. Even low levels of lead exposure can cause health effects.
Single venous blood lead level. The CDC-recommended definitive lead exposure test — replaces fingerstick capillary lead testing (which has higher false-positive rates).
Children in older housing (pre-1978 paint), pregnant women, occupational exposure (construction, demolition, shooting range, auto repair), recent immigrants from countries with leaded gasoline, or anyone with cognitive/behavioral concerns from possible exposure.

A Lead Test costs $28.99 at TestWell — $34.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $52.00 at Quest Health (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $150.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

CDC's reference value: 3.5 mcg/dL for children. There is no safe blood lead level — any detectable lead is associated with measurable cognitive impact. >5 mcg/dL warrants intervention; >45 typically requires chelation.
TestWell charges $28.99 — vs $49 at Quest Direct and $80-$200 at pediatric/occupational clinics.
Lead has a long bone half-life (~25 years). Blood half-life is much shorter (~30 days) and reflects recent exposure. After removing the source, blood levels drop within weeks but bone stores release lead for decades — which is why chelation is sometimes recommended for very high levels.
