Are there any upper limits to allowed level of lead in blood?
Several organizations and laboratories have recommended upper limits of blood lead levels and these recommended levels are medically termed as Elevated Blood Lead (EBL) Levels. Frequently allowed lead levels are around 10 mg/dl while on the ppm (parts per million) scale, permitted levels range between 250ppm – 1000ppm. So, Body Lead Levels of 10 mg/dl or higher, obtained with capillary lead testing must be followed with a confirmatory venous test. The ratio of BLL (Body Lead Level) to the EBLL (Elevated Body Lead Level) is one of the major decisive factors for further medical support to be taken.
