We describe a sensitive and specific method for measuring cotinine in serum by HPLC coupled to an atmospheric pressure chemical ionization tandem mass spectrometer. This method can analyze 100 samples/day on a routine basis, and its limit of detectio

On July 10, 1976, an explosion at a chemical plant near Seveso, Italy, released a mixture of chemicals, including 2,3,7,8-tetrachlorodibenzo-p-dioxin and 2,4,5-trichlorophenol. As a result, several thousand people in the Seveso area may have been exp

Recommendations for the selection and use of protocols for assignment of values to reference materials

Autor: A M, Johnson, E J, Sampson, S, Blirup-Jensen, P J, Svendsen

Publikováno v: European journal of clinical chemistry and clinical biochemistry : journal of the Forum of European Clinical Chemistry Societies. 34(3)

It is essential that testing of patient samples give values that are traceable to those in a recognized, authorizative reference material. In addition, samples used for laboratory proficiency testing must have values assigned from such a reference ma

Recent advances in techniques to measure markers of exposure to environmental toxicants in humans are changing the ways in which environmental scientists, epidemiologists, and policymakers characterize and interpret such exposure. In this article we

Estimating and minimizing effects of biologic sources of variation by relative range when measuring the mean of serum lipids and lipoproteins

Autor: G R, Cooper, S J, Smith, G L, Myers, E J, Sampson, E, Magid

Publikováno v: Clinical chemistry. 40(2)

Biologic intraindividual variation (CVb) is a major source of inaccuracy in current lipid and lipoprotein measurements. Metaanalysis has been used to estimate the average CVb of serum total cholesterol (TC), high-density lipoprotein cholesterol (HDLC

Tryptophan contaminants associated with eosinophilia-myalgia syndrome. The Eosinophilia-Myalgia Studies of Oregon, New York and New Mexico

Autor: R M, Philen, R H, Hill, W D, Flanders, S P, Caudill, L, Needham, L, Sewell, E J, Sampson, H, Falk, E M, Kilbourne

Publikováno v: American journal of epidemiology. 138(3)

Eosinophilia-myalgia syndrome (EMS) has been linked to ingestion of tryptophan contaminated with 1,1'-ethylidene-bis[L-tryptophan] (EBT), but other contaminants have received little study. The authors identified 101 lots of L-tryptophan that had been
