Fully automated capillary blood collection

See Product Summary

Health ID MicroBlood™

The Health ID MicroBlood™ is a fully automated capillary blood collection system that delivers liquid blood samples — up to 1 mL — directly into commercial microtubes, without venous puncture.

Applied to the upper arm, MicroBlood™ integrates lancet activation and controlled vacuum extraction in a single device. After activation, the system performs a precise microincision and automatically draws blood — minimizing operator dependence and standardizing one of the most variable steps in the diagnostic chain.

What you need to know

  • How does the collection process work?

    MicroBlood™ is applied to the upper arm. Once activated, the device performs a controlled microincision and initiates automatic vacuum-assisted extraction, channeling liquid blood into a standardized microtube. The procedure takes only a few minutes and requires no venous puncture.

  • Is self-collection possible?

    Yes, it is. The procedure is designed to be user-friendly, requiring only a quick fingerstick to extract a few drops of blood. Afterward, just pack the device in the transport pouch and send it off. No special storage or complex shipping logistics are needed.

  • Is specialized logistics required?

    No, specialized logistics are not necessary. After collection, the sample dries within the device, with desiccants and oxygen scrubbers ensuring long term stability. The device desing minimizes contamination risks and enables safe shipping using standard transportation methods.

  • What is the analytical performance?

    After applying 4 drops of blood, an average of 18.4 µL of plasma was recovered on an 85 mm² dried separation membrane, with a coefficient of variation (CV%) of 18.8%. Use of a correction analyte is recommended for optimal accuracy.


    The device’s analytical performance has been validated for cholesterol, HDL-cholesterol, triglycerides, and creatinine. With chloride concentration normalization, inter-assay imprecision ranged from 2.89% to 4.99%, and intra-assay imprecision from 3.29% to 4.85%. The mean bias for estimated serum concentrations from dried plasma measurements ranged between -0.74 and 1.64%.


    No statistically significant differences were observed in corrected concentrations for blood volumes of 160, 200, and 240 µL. Similarly, samples with hematocrit levels of 30% and 50% showed no significant differences compared to the reference hematocrit of 40%.


    Analyte stability is confirmed for at least 14 days at 40°C when stored within the device’s protective pouch.


    Additional validation studies are ongoing.

  • When is MicroBlood™ most beneficial?

    Remote patient monitoring, decentralized clinical trials, chronic disease follow-up, pediatric or difficult venous access patients, and any decentralized healthcare model requiring standardized liquid capillary samples.

GC-NPD analysis of topiramate in capillary dried plasma

By Isabela Ritter Ott, Debora Renata Macali Oliveira, Ana Paula Grando, Klaus Vogel Frohlich, Magda Susana Perassolo, Rafael Linden & Marina Venzon Antunes • May 20, 2024
The study developed and validated a GC-NPD method for the quantification of topiramate (TPM) in capillary dried plasma spots (DPS) obtained using the HealthID PSD microsampling device. The method demonstrated good precision and accuracy, and TPM was shown to be stable in DPS stored at 4°C, 23°C, and 45°C for up to 21 d
