Abstract An extraction method and apparatus is provided for obtaining quick, safe and highly sensitive testing of any of a variety of body fluids including saliva, blood, urine or other fluids for drugs of abuse or other analytes. The apparatus includes a latchable extraction wand for obtaining body fluid samples from a subject which is adapted to maximize the portion of the body fluid sample that will go into a graduated bottle containing a buffer solution, and a testing device wherein the sample will be received and into which test strips can be inserted to determine levels of drugs of abuse or other analyte in the sample. In one of the methods of the invention, energy is imparted to the sample and buffer solution, such as by shaking, and this facilitates the reduction of sample viscosity, such as by promoting the breakdown of mucins when the sample is saliva. Se proporcionan un método y aparato de extracción para la obtención de prueba rápida, segura y altamente sensible de cualquiera de una variedad fluidos corporales que incluyen saliva, sangre, orina u otros fluidos para abuso de fármaco u otros analitos. El aparato incluye una varilla de extracción que se puede cerrar para obtener muestras de fluido corporal de un sujeto que está adaptada para aumentar al máximo la porción de la muestra de fluido corporal que irá dentro de una botella graduada que contiene una solución reguladora de pH, y un dispositivo de prueba en donde la muestra será recibida y dentro del cual pueden ser insertadas tiras de prueba para determinar los niveles de abuso de fármacos u otro analito en la muestra. En uno de los métodos de la invención, se imparte energía a la muestra y la solución reguladora de pH, mediante agitación, y esto facilita la reducción de la viscosidad de la muestra, por ejemplo al promover la separación de mucinas cuando la muestra es saliva.
