Point-of-Care-Testing

"Real-Time Data for Real-Time Decisions"

 

What Is Point-of-Care-Testing ?

  • Definition: Medical diagnostic testing performed near the patient, often at the bedside, providing rapid results to support immediate clinical decision.

  • Common Setting: Hospitals, physicians  offices, urgent care centers, pharmacies, skilled nursing facilities, and even remote locations like cruise ships or in-home.

​

Key Benefits for Patients and Providers

  • Rapid Results: Turnaround times are significantly shorter than traditional lab tests, often yielding results within minutes (e.g., 1-20 minutes)

  • One-Visit Care: Patient can be tested, diagnosed, and treated during a single visit, reducing the need for follow-up appointments and calls.

  • Improved Outcomes: Faster diagnosis allows for immediate initiation of treatment, which is critical in emergency situations like suspected heart attacks or sepsis.

  • Better Resource Management: Helps clinicians rule out conditions quickly, reducing unnecessary hospital admissions and streamlining triage in over crowed settings.

How It's Collected
For most point-of-care-tests, you only need a single drop of blood (about 10 to 40 microliters).To put that in perspective, a standard drop of water is about 50 microliters, so these tests usually require significantly less than that. Because the volume is so small, these are almost always "finger-stick" tests. A small capillary tube (a tiny glass or plastic straw) that automatically sucks up the exact amount of blood needed when the tube is touched to the blood drop. Other samples that may be used depending on the test ordered includes: whole blood, urine, saliva/Oral Fluid, Swabs (Nasopharyngeal/Oropharyngeal, Fecal Matter, less common POCT samples include sweat(for drug testing), tears, and interstitial Fluid (used in continuous glucose monitoring). There are some POCT testing that does not require a sample directly from the patient, information is collected through "physical POCT" devices(like breath, skin, and direct Sensors like your pulse.
