Designed to produce high-quality samples as small as a pea.
Babson Diagnostics’ new collection technology is designed to:
- Collect less than one-tenth the volume—an amount as small as a pea.
- Collect capillary blood from the fingertip instead of venous blood from the arm.
- Prevent the typical pitfalls of capillary collection, producing high-quality samples that enable results clinically equivalent to those from venipuncture.
- Enable sample collection by any trained health care worker, which eliminates the need for a specially-trained phlebotomist and provides the opportunity to bring diagnostic testing to convenient retail pharmacies.
A new chapter for collection technology
The status quo is a tradeoff between quality and convenience.
Venipuncture—drawing blood from a vein in the arm—reliably produces samples of high enough quality to produce diagnostic results, and that is why it has remained the standard method for over 70 years, despite drawbacks including:
- Physical and psychological discomfort.
- The large amount of blood drawn, typically 4-10mL.
- Requiring a specially-trained phlebotomist, causing the need for centralized collection sites with large waiting rooms.
Customer demand has led to exploration of capillary (fingertip) collection, but diagnostic testing usually requires venipuncture, because the nature of capillary collection presents broad obstacles to sample quality:
- Slow collection causes excessive evaporation, gas exchange, and clotting.
- Measures used to speed up collection present other problems; vacuum pressure and squeezing cause hemolysis, and using multiple needles contaminates the sample with interstitial fluid and cellular material.
The future of blood testing is quality and convenience combined.
Babson Diagnostics is developing new capillary collection technology designed to:
- Mitigate contamination by interstitial fluid and cellular material.
- Stop premature clotting.
- Prevent hemolysis.
- Collect pea-sized samples with quality appropriate for diagnostic testing, producing results clinically equivalent to those from venipuncture.
- Enable any trained health care worker to collect samples, removing the need for phlebotomists and, in turn, allowing us to bring diagnostic testing to convenient retail pharmacies.
Clinical studies are ongoing to validate this technology in retail environments.
