What can you see in the blood smear of patients with lead poisoning?

Peripheral blood smear shows basophilic stippling in several red cells from a patient with lead poisoning. The granules represent ribosomal precipitates. A similar picture can be seen in a number of other conditions including thalassemia, megaloblastic anemia, sickle cell anemia, and sideroblastic anemia.

What is the best test for lead poisoning?

A simple blood test can detect lead poisoning. A small blood sample is taken from a finger prick or from a vein. Lead levels in the blood are measured in micrograms per deciliter (mcg/dL).

Why does lead cause basophilic stippling?

In contrast to fine basophilic stippling in thalassemia, basophilic stippling is typically coarse in lead poisoning as a result of precipitation of RNA secondary to pyrimidine-5′-nucleotidase inhibition. Coarse basophilic stippling is also reported in pyrimidine-5′-nucleotidase deficiency and arsenic poisoning.

What does lead poisoning do to blood cells?

In vitro, the exposure to a very small amount of lead greatly changes the surface of the red blood cells. Their permeability to water is so altered that they shrink and are incapable of swelling as much as normal cells.

Can lead poisoning damage kidneys?

Kidney damage from lead exposure is very uncommon in the United States. In fact, most experts believe that kidney damage from lead is rare nowadays, especially in the United States and Europe. It’s believed that lead exposure causes less than 1% of all cases of kidney failure.

Is lead poisoning acute or chronic?

Lead poisoning may be acute (from intense exposure of short duration) or chronic (from repeat low-level exposure over a prolonged period), but the latter is much more common.

What is sideroblastic anemia?

Sideroblastic anemia is a group of blood disorders characterized by an impaired ability of the bone marrow to produce normal red blood cells . In this condition, the iron inside red blood cells is inadequately used to make hemoglobin, despite normal amounts of iron.
