Title: Innovations by John W. Goodin: A Pioneer in Specimen Testing

Introduction

John W. Goodin, based in Coto de Caza, California, is a prolific inventor known for his contributions to fluid specimen testing technology. With an impressive portfolio of 55 patents, Goodin has focused his efforts on developing innovative methods and systems that enhance the accuracy and security of specimen handling and testing.

Latest Patents

Among his latest innovations, Goodin has developed a "Method of Securing a Chain of Custody of a Specimen of a Donor." This method effectively prevents tampering or accidental mismanagement of specimens by implementing a tamper-evident seal. This seal is designed to indicate if an assaying device has been compromised, featuring a label with a machine-readable indicia area.

Additionally, he created a "System for Automatically Testing a Fluid Specimen," which indicates the presence of specified chemical components in a specimen. This advanced system utilizes an assaying device with a collection cup and a cap that carries a test strip. It includes an integrated aliquot delivery mechanism, which automatically wets the test strip with an aliquot from the fluid specimen. The system operates alongside an electronic reader device designed to actuate the delivery mechanism and analyze the test strip's reaction.

Career Highlights

Throughout his career, Goodin has worked with notable companies such as Escreen, Inc. and Cambro Manufacturing Company. His expertise in specimen analysis and testing has positioned him as a valuable contributor to the fields of healthcare and laboratory technology.
