Description
The Covaris truCOLLECT Whole Blood Collection Kit is a participant-ready self-collection system designed for decentralized genomics studies. The kit includes all materials and instructions required to quickly and easily collect 50 µL of whole blood via the enclosed fingerstick device.
No in-clinic visit. No cold-chain handling. No specialized storage requirements.
Covaris proprietary desiccation technology stabilizes whole blood within the truCOLLECT collection device at ambient temperature, preserving analyte integrity for downstream extraction, purification, and analysis while eliminating the logistical burden and expense of temperature-controlled transport.
Designed for intuitive, participant-friendly operation, the truCOLLECT Whole Blood Collection Kit reduces other important barriers associated with traditional phlebotomy.
For research teams, this means greater access to:
- Rural and geographically dispersed populations – enables participation without traveling long distances
- Elderly, pediatric, and limited-mobility participants – volumetric sampling, easy fingerstick format, and in-home convenience can increase study compliance
- Participants in longitudinal or high-frequency sampling studies – increases compliance for participants required to provide repeated samples
- Underrepresented populations in biomedical research – improves inclusion of communities with historically lower participation rates due to socioeconomic, proximity, or other barriers
- Participants in global population studies – stabilization technology and standardized processing workflow simplifiy logistics and reduce cost of large-scale recruitment
For laboratory teams, this unique self-collection format enables operational flexibility, significant cost savings, simplified sample intake, and standardized remote sample collection and processing at scale.
The truCOLLECT Whole Blood Collection Kit serves as the first component of the broader truCOLLECT Solution, which integrates collection with an extraction workflow enabled by Adaptive Focused Acoustics® (AFA®) to support consistent, sequencing-ready analyte recovery.

Consistent DNA Quality and Quantity
The truCOLLECT Solution enables reliable and consistent DNA recovery from samples stored at room temperature (100% across cohort size of 94).Stability at ambient temperature minimizes pre-analytical variability, which is common to other sample collection methods.
DNA Stability Over Time
Whole blood samples processed with the truCOLLECT Solution maintain consistent DNA quantity and quality across multiple donor samples after storage at room temperature for 3-6 months (DNA quantity correlated with white blood cell counts).Samples also demonstrated stability across extreme temperature conditions (50-75° C)
truCOLLECT Solution FAQs
Capillary blood collection devices may be used in research to obtain small volumes of blood without traditional venipuncture. However, collecting the sample is only the first step; preserving analytes and efficient extraction and purification of biomolecules from small-volume samples is critical for reliable downstream molecular analysis. The truCOLLECT device combines capillary blood collection (fingerstick) with active sample stabilization and is also a key component of a broader, optimized extraction and purification workflow. This optimized workflow approach enables higher yield recovery of analytes from stabilized blood samples, suitable for applications such as genomic DNA analysis, while also supporting greater laboratory efficiency and automation capability.
Dried blood spot (DBS) cards have historically been used for small-volume blood collection in research studies, but the drying process and extraction methods can limit analyte recovery and introduce variability in downstream molecular analysis. In addition, DBS approaches may provide limited suitability for genomic workflows due to challenges in recovering consistent, high-quality DNA from dried blood. The truCOLLECT Solution enables stabilized capillary blood collection and controlled rehydration prior to extraction, supporting broader analyte recovery and more consistent genomic DNA analysis for modern molecular workflows.
Distributed research programs often require complex sample collection, transport, and processing workflows. Stabilized capillary blood collection enables samples to be collected remotely and transported at ambient temperature prior to extraction. By reducing the need for immediate processing and specialized handling, approaches such as the truCOLLECT Solution can simplify study logistics and help lower operational costs associated with sample transport and processing while maintaining compatibility with downstream molecular workflows.
