What Is Point-of-Care Testing in Relation to NG and OG Tubes?

Point-of-care testing (POCT) refers to medical diagnostic testing that is performed near the patient, at the point of care, rather than in a central laboratory or healthcare facility. 

One area that demands particular attention is the use of nasogastric (NG) and orogastric (OG) tubes in clinical settings. Point-of-care testing has emerged as a valuable tool in providing rapid diagnostic results, promoting effective decision-making, and improving patient outcomes.

POCT can be conducted using various devices, such as handheld analyzers, portable diagnostic instruments, pH indicators for NG/OG tube placement, or even smartphone applications. These devices are designed to be user-friendly and require minimal training to operate. 

Why Point-of-Care Testing Is Needed for NG and OG Tubes

Using NG and OG tubes comes with risks, but with point-of-care testing, those risks are minimized. Two reasons POCT is needed at the bedside include:

Enhancing Efficiency at the Bedside

Traditionally, NG and OG tubes have been utilized for various medical purposes, such as administration of medications, enteral feeding, gastric decompression, or drainage. However, these tubes also pose potential risks, including infection, aspiration, and tube displacement. The timely monitoring of tube positioning and the assessment of gastric residual volume are crucial to prevent adverse events and ensure appropriate patient management.

Confirming Accurate Positioning

Diagnosing the correct positioning of NG and OG tubes accurately is imperative to avoid complications. Historically, radiographic imaging, including X-ray, has been the standard for verifying tube placement, but this method can be time-consuming, expensive, and may delay necessary interventions. This is where point-of-care testing comes into play, offering real-time insights that expedite decision-making and circumvent the need for portable imaging.

Advantages of POCT in Regards to Tube Placement

When it comes to NG and OG tube placement, POCT offers several advantages:

Rapid Confirmation

With the help of specialized pH testing devices from RightBio Metrics, healthcare providers can quickly and easily assess the pH level of aspirated gastric contents, effectively confirming proper tube placement in the stomach. This simple POCT procedure eliminates unnecessary delays in initiating appropriate care and minimizes the risks associated with incorrect tube positioning.

Improved Patient Safety

POCT plays a vital role in gauging gastric residual volume. By accurately determining the amount of residual material in the stomach, healthcare professionals can make informed decisions regarding enteral feeding, medication administration, or even surgical interventions. This minimizes the risk of aspiration, enhances patient comfort, and avoids other potential complications.


Utilizing POCT for NG and OG tube management reduces the reliance on expensive radiological examinations, resulting in significant cost savings for healthcare facilities. The ability to perform real-time assessments at the bedside prevents unnecessary patient transfers and optimizes the allocation of healthcare resources.

Enhanced Efficiency

The convenience and simplicity of POCT for NG and OG tubes streamline clinical workflows, enabling faster decision-making and facilitating earlier intervention. POCT empowers healthcare providers to promptly address critical issues, such as tube dislodgement or improper position, ensuring timely corrective measures and avoiding any adverse consequences for the patient.
