What kind of sample is required for lead testing (air, blood, surface)?
Different samples can be used to test for lead exposure, depending on what you're trying to assess. For personal exposure in workers, blood samples are the gold standard – they directly measure how much lead is in the body. Air samples are often collected at job sites to check how much lead is floating around in the air workers are breathing. Surface samples, like dust wipes or swabs, help assess environmental contamination, especially in buildings. Each sample type gives a different piece of the picture, and they’re often used together to understand risk more fully.
