Semi-automated capillary blood collection

See Product Summary

Health ID MicroFlow™

The Health ID MicroFlow™ is a vacuum-assisted liquid blood collection device designed for arm-based capillary sampling — engineered to combine the simplicity of manual procedures with the consistency of automated extraction. The procedure starts with a manual lancet puncture, guided by a positioning template that ensures precise alignment between the incision and the device. Once attached, MicroFlow™ automatically performs controlled vacuum extraction, collecting up to 1 mL of liquid capillary blood directly into a commercial microtube ready for laboratory workflows. By separating puncture and extraction, MicroFlow™ reduces mechanical complexity without sacrificing automation — a strong fit for large-volume, cost-sensitive collection programs.

See how it works

Before Collection

Prepare the skin, apply the positioning template to the upper arm and perform the lancet puncture at the indicated location.

Instructions for use

During Collection

Attach the MicroFlow™ to the template and press the activation button. Vacuum-assisted extraction runs automatically.

Instructions for use

After Collection

Remove the device from the upper arm. Afterwards, remove the filled microtube and prepare the sample for transport to the laboratory.

What you need to know

  • How does MicroFlow™ differ from fully automated devices?

    MicroFlow™ separates puncture from extraction. The lancet step is performed manually with a guided template; the vacuum extraction step runs automatically. This split reduces mechanical complexity while preserving consistency.

  • Is self-collection possible?

    MicroFlow™ is primarily designed for assisted or guided environments but can be adapted for supervised home programs with appropriate training and kits.

  • Why is a positioning template needed?

    The template ensures precise alignment between the puncture site and the device seal — improving collection consistency and success rate.

  • Which sample formats are supported?

    Liquid capillary blood in commercial microtubes — including EDTA, Heparin, Serum and other additives, per laboratory protocol.

  • When is MicroFlow™ most beneficial

    Large-scale collection programs, laboratory networks, decentralized clinical studies, cost-sensitive deployments and any scenario where automated extraction must be paired with simplified mechanics.
