What is a PB test?
This test measures the amount of lead in a person’s blood. Lead is a poisonous (toxic) metal that can damage the brain and other parts of the body. A lead test may be done on blood taken from the vein, a finger (finger stick), or the heel (heel stick).
Does a CBC test for lead?

What is a lead test called?
A finger-prick or heel-prick (capillary) test is usually the first step to determine if a child has lead in their blood. While finger-prick tests can provide fast results, they also can produce higher results if lead on the skin is captured in the sample.
How does EDTA treat lead poisoning?

What is a toxicity test?
These tests are called toxicity tests. Government regulations often prescribe a specific regimen of toxicity testing to generate the data that enable regulators to determine the chemical’s risks to human health and/or the environment.
What are the adverse outcomes of toxicity testing?
In addition to what there are numerous specialized toxicity testing procedures that can be used to assess specific adverse outcomes, such as birth defects, reproductive capacity, neurological and behavioral effects, and toxic effects on the immune system, to name a few ( Hayes, 2001 ). Table 1. Typical approaches to toxicity testing.
Should animals be used as models for toxicity testing?
There is a long history in the use of animals as models for toxicity testing. During the 20th century, as regulatory agencies were established by national governments, animal test guidelines were developed to address regulatory requirements that products need to be “safe” for consumers.
What is the testing process for determining toxicity in marine environments?
