Why it matters

Usability is a
medical feature.

User error is the real barrier to remote blood collection (anxiety, inadequate volume, hemolysis). By collecting from the upper arm rather than a coaxed fingertip, TAP removes the friction that makes people fail on the first try, and a first-try failure is a lost sample and a lost patient.

Touch-activatedPress to the upper arm and the device does the work, no lancing step for the patient to get wrong.
Liquid whole bloodThe same matrix as a venous draw, collected in microsample volume for a broad validated panel.
Self-collectedDesigned for at-home use with app-guided instructions, per the manufacturer.
The technology

Powered by HALO™.
Deep enough to work.
Shallow enough not to hurt.

HALO is a bladeless microneedle array (thirty micro-points, each finer than a human eyelash, integrated into a single ring). Nothing cuts and nothing lances.

A TAP Micro Select collection, start to finish A heat pad is held on the upper arm while a chronograph counts four minutes, and the warmed skin takes on a faint colour. The device is applied. A capped tube is uncapped and attached to the device's port, and only then is the device applied to the arm. The plunger is pressed, driving the micro-point array into the skin. The skin lifts, the sample beads and runs down into the tube, the device is lifted away, the tube is detached and then capped.

  5. Detach

Hold the heat pad on the upper arm for four minutes. Warming dilates capillary blood vessels and raises capillary flow at the surface, which is what the draw volume depends on.

Connect the BD Microtainer, and stick the device to the upper arm (the adhesive will keep the device in place).

One press of the plunger until “click” drives the microneedle array through the surface of the skin. Releasing the plunger pulls the micro-points back, and activates the vacuum.

About a minute and a half draws a liquid whole-blood sample into a BD Microtainer tube (the standardised tube the laboratory already runs).

Detach the device, wipe any remaining extra blood on the arm and apply the patch. Cap the tube and drop it in the tracked mailer. Chain of custody from the first second.

Five steps. Four minutes warming, a minute and a half collecting.

The TAP Micro Select, drawn from the side and from the skin Two views at the same scale. From the side: the plunger above a body that tapers outward to its base, with the tube port projecting low on one side. From the skin: the adhesive liner across almost the whole footprint with a small opening at its centre, redrawn enlarged alongside to show thirty micro-points in a close ring.

How deep the micro-points go A section through skin scaled in millimetres: epidermis, dermis and subcutis, with the dermal nerve plexus low in the dermis and fibres rising from it to the surface. Thirteen of the array's thirty micro-points are drawn as a row, each a thousand microns long and fifty-six microns across. They are driven in to just under one millimetre (inside the dermis, above the one-millimetre mark and above the plexus) then withdraw as the skin lifts onto them under vacuum and the sample beads at the foot of the lift.

At 1,000 µm long, the micro-points are built to reach the capillary bed and stop short of the pain receptors below it, which is why patients describe the collection as virtually painless next to a finger stick, a lancet or a venepuncture. Asked to compare the two directly, 63% preferred it to a needle and just 7% preferred the needle.

Thirteen years of restraint.
Then a sticker.

University Hospitals of Morecambe Bay NHS Foundation Trust ran a small trial (twenty patients, several devices) looking for one that would work for people with learning disabilities, for whom a venepuncture can mean being held down. YourBio TAP is the one they kept.

Abi is fifteen, has Down’s syndrome, and needs regular thyroid monitoring. Her mother counts thirteen years of blood tests that ended in tears and restraint (for everyone in the room, not just for Abi). At a routine annual health check her nurse offered the new method instead. Abi calls it fun.

The first clinic anywhere.
And it was fertility.

Monitoring one round of IVF asks for around six blood draws in a fortnight, in the same arm, at the most stressful time of a person’s life. The Columbia University Fertility Center in New York replaced those draws with a TAP collection and says it became the first place anywhere to use this kind of technology in clinical care (in any specialty, not only fertility).

What made it possible was not the device alone: it took laboratory chemistry able to read hormones from the amount of blood the device gives you, which is roughly a tenth of a standard draw. Device and assay, together. That pairing is the whole argument for putting this on a platform rather than buying it as a product.

Both films, and the figures and quotes drawn from them, belong to the institutions that made them, University Hospitals of Morecambe Bay NHS Foundation Trust and Columbia University Irving Medical Center. They report their own programmes; neither is a Humans Nexus study. TAP is the YourBio device curated on this platform.

On the platform

Assembled into a kit.

YourBio is curated onto the platform and assembled into a regulated Humans Nexus collection kit (device, skin prep, BD Microtainer collection tube, tamper-evident return mailer and app-guided instructions, under its own UDI). The TAP Micro Select is built to collect straight into the BD Microtainer, so the sample reaches the lab in the standardised, colour-coded microtube it already trusts.

Logistics

A liquid sample, handled.

Liquid capillary blood is a liquid matrix, so it is handled where the assay requires it (controlled-temperature transport, temperature-logged from collection to accessioning, through Humans Nexus logistics, tracked on the platform). Dried formats ship ambient; liquid is the managed exception, applied only where the panel needs it.

Good to know.

Is YourBio painless?

YourBio describes the collection as virtually painless. It collects from the upper arm through micro-points rather than a fingertip lance, avoiding the sting and squeeze of a fingerstick. Comfort claims are attributed to the manufacturer.

Is the YourBio TAP the same as the TAP Micro Select?

Yes. YourBio Health makes the TAP® family; the TAP® Micro Select (also written Microselect) is the model on this page, and the one Humans Nexus distributes. If you have seen it called simply the YourBio TAP, that is the same device.

What does it collect?

A liquid whole-blood sample (the same matrix as a venous draw, in microsample volume, suitable for a broad validated panel).

What tube does the blood go into?

A BD Microtainer (the TAP Micro Select is built to collect capillary blood straight into it, so the sample arrives in the standardised, colour-coded microtube the laboratory already runs and can process like any other).

Who can use it?

Adults self-collect at home with app-guided instructions, per the manufacturer, including the needle-averse and remote patients. In children, the device is used under healthcare-professional supervision, at the practice or the point of care.

What is its regulatory status?

YourBio is FDA-cleared and CE-marked per the manufacturer. Device-level regulatory status is held by YourBio; Humans Nexus curates and supplies the device and assembles the regulated kit around it.

Does it need cold chain?

As a liquid matrix, it is handled with controlled-temperature transport where the assay requires it, temperature-logged end to end on the Humans Nexus platform.

The evidence base

Everything published on collecting blood this way.
