Semi-automatic determination of lead in whole blood

Journal of Clinical Pathology
H T Delves, P Vinter

Abstract

The procedure developed by Browett and Moss (1964) for the semi-automatic determination of the lead content of urine has been adapted for the determination of lead in blood. Determinations are normally carried out in duplicate on 2.0 ml. samples of whole blood and the minimum sample size is 0.5 ml. The organic substances present in blood are destroyed by a manual wet-oxidation procedure and the lead is determined colorimetrically as lead dithizonate using a Technicon AutoAnalyzer. The lower limit of detection, expressed as three times the standard deviation of the blank value, is 5 mug. Pb/100 ml. blood. The standard deviation of the method in the upper range of normal blood lead level of 30 mug. Pb/100 ml. blood (Moncrieff, Koumides, Clayton, Patrick, Renwick, and Roberts, 1964), is +/- 3 mug. Pb/100 ml. blood. Ten samples per hour may be estimated in duplicate.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
