Blood Lead Level Test is the best way to determine whether a person/child has lead poisoning.

• A. Urinalysis
• B. Blood Lead Level Test
• C. X-ray
• D. Skin test

Answer: (B)

The essential idea is that lead poisoning is diagnosed by measuring how much lead is present in the blood. The blood lead level test directly quantifies lead in the bloodstream, which reflects recent exposure and the risk of harm. This makes it the most reliable and actionable test for determining whether someone, including a child, has lead poisoning. Results are given as a lead concentration in blood (usually in micrograms per deciliter), guiding treatment and follow-up. Urinalysis checks kidney function or other urinary abnormalities but does not tell you how much lead is in the body. X-rays can show certain long-term effects of lead or locate lead-containing objects, but they do not provide the current body burden or a poisoning level. Skin tests are not used to detect lead exposure or poisoning. So the blood lead level test is the best method to determine lead poisoning.
