Abstract:
1. A method of determining the concentration of one or more than one compound in a sample comprising, (a) placing a receptor over a portion of a body part, and either (i) directing a source of electromagnetic radiation (EMR) through the receptor and the body part; (ii) lancing the body part to obtain sample of blood and directing the source of electromagnetic radiation (EMR) through the receptor and the sample of blood; or (iii) directing the source of electromagnetic radiation (EMR) through the receptor and the body part, and lancing the body part to obtain sample of blood and directing the source of electromagnetic radiation (EMR) through the receptor and the sample of blood; (b) measuring a quantity of the EMR reflected by, or transmitted through, the body part, sample of blood, or both the body part and the sample of blood with a detector; and (c) performing a quantitative mathematical analysis of the quantity of EMR using an algorithm, and determining the concentration of the one or more than one compound in the body part, the sample of blood, or both the body part and the sample of blood, wherein the one or more than one compound may be selected from the group consisting of a neutral or ionic form of a heavy metal having an atomic number greater than 20, wherein prior to the step of directing the EMR on the body part, in steps a) i) or a) iii), the body part is squeezed so that a substantial portion of the blood is removed from the body part to produce a squeezed body part, the EMR is directed onto the squeezed body part, and the one or more than one compound is determined within the squeezed body part.
