What Are Micro Capillary Tubes
Micro capillary tubes are small, cylindrical tubes used in point-of-care diagnostics. They are designed to quickly and accurately collect and process a sample for rapid detection of pathogenic organisms or disease markers.
The tiny tubes contain a narrow channel that can be filled with fluids such as blood, urine, saliva or other bodily fluid for analysis. The inside surface of the tube is lined with chemical reagents that react with the collected sample. These reactions allow for quick identification and quantification of the sample's contents.
Benefits of Micro Capillary Tubes
Utilizing these miniature devices offers numerous advantages in point-of-care settings.
Micro capillary tubes (MCTs) provide rapid testing, sample preparation, and minimized effort for healthcare professionals due to:
- Enhanced Accuracy:
- Automated readouts can detect even trace amounts of substances accurately.
- Minimized risk of manual errors or contamination.
- Streamlined Process:
- Efficiency increases with MCTs due to high throughput capabilities.
- Reduced steps required to obtain results allows for quick decisions and efficient treatment plans.
Types of Micro Capillary Tubes
Different types of MCTs exist, each offering distinct advantages for healthcare professionals in point-of-care settings.
Rapid tests are one type that can offer results quickly and accurately with minimal sample collection. These tests allow for noninvasive sampling such as capillary blood or urine, and provide a fast turnaround time from patient to result.
Another type of MCT is an integrated device containing the entire test procedure in the same platform, allowing easier interpretation of results than traditional testing methods.
Finally, there are disposable microfluidic cartridges which provide rapid analysis with high accuracy.
Each type has its own unique features which can be beneficial to healthcare professionals when conducting point-of-care testing.
