It is usually taken by location a vein in the inside of the ar by using a sterile needle. Once a sample is removed the technician will apply a bandage for the wound to keep it from bleeding and prevent bruising.

|Less than 23 µg/L||Normal(URINE)|
|50 to 79.9 µg/dl||Immediate evaluation|
|80 & Above||Chelate|
|00 to 9.9 µg/dl*||No additional action|
|10 to 24.9 µg/dl||Identify and minimize exposure|
‘*A Reference range is a set of values which helps the healthcare professional to interpret a medical test. It may vary with age, gender, and other factors. Reference ranges may also vary between labs, in value & units depending on instruments used and method of establishment of reference ranges’
When there is a high level of lead in the blood, especially in children, lead treatment should be sought immediately. Adults generally have a higher threshold for lead poisoning, but if the exposure is too high then the doctor recommends a chelation therapy.
