Point-of-Care Testing
A medical diagnostic approach that enables rapid testing and clinical decisions by performing laboratory tests near or at the site of patient care.
Point-of-Care Testing
Point-of-Care Testing (POCT), also known as near-patient testing, represents a transformative approach to medical diagnostics that brings laboratory testing directly to the patient's location, whether at the bedside, in a clinic, or even at home.
Core Principles
The fundamental aspects of POCT include:
- Rapid result generation (typically within minutes)
- Minimal sample preparation requirements
- Portable or handheld testing devices
- Immediate clinical decision-making capability
- Reduced need for laboratory infrastructure
Common Applications
Clinical Settings
- Blood glucose monitoring for diabetes management
- Blood gas analysis in emergency departments
- Cardiac markers for heart attack diagnosis
- infectious disease screening
- Coagulation testing
Community Settings
- Home pregnancy tests
- Drug screening
- telehealth monitoring systems
- public health screening programs
Technical Components
Modern POCT devices typically incorporate:
- biosensors
- Microfluidic systems
- Digital readouts
