Chemical assays--new opportunities

Area of Science:

• Clinical Chemistry
• Biotechnology

Background:

• Solid-phase test formats are increasingly accepted in clinical chemistry.
• Advantages include reagent stability, unitized packaging, and minimal user preparation.

Purpose of the Study:

• To review the advantages of solid-phase formats in clinical chemistry.
• To identify user needs for decentralized and home testing systems.
• To discuss emerging solid-phase technologies.

Main Methods:

• Literature review of solid-phase test formats.
• Analysis of user requirements for clinical laboratory and home testing.
• Overview of new technological developments in solid-phase assays.

Main Results:

• Solid-phase tests offer convenience but require further improvements for specific applications.
• Decentralized labs need lower costs, enhanced convenience, and better quality control.
• Home testing demands clinical accuracy, improved quality control, and reliable result recording.

Conclusions:

• Future success of solid-phase reagents hinges on meeting user needs for convenience, cost, and accuracy.
• New technologies like noncolorimetric and spectrophotometric systems show promise for in vitro, in vivo, and non-invasive testing.
