Diagnosis of elemental or inorganic<unk>  involves determining the history of exposure, physical findings, and an elevated body burden of<unk> . Although whole-blood<unk>  concentrations are typically less than 6 μg/L, diets rich in fish can result in blood<unk>  concentrations higher than 200 μg/L; it is not that useful to measure these levels for suspected cases of elemental or inorganic poisoning because of<unk> 's short half-life in the blood. If the exposure is chronic, urine levels can be obtained; 24-hour collections are more reliable than spot collections. It is difficult or impossible to interpret urine samples of people undergoing chelation therapy, as the therapy itself increases<unk>  levels in the samples. Diagnosis of organic<unk>  differs in that whole-blood or hair analysis is more reliable than urinary<unk>  levels.
