Neoteryx Mitra.
Exact volume, single touch.
Neoteryx Mitra captures a fixed, precise volume of capillary blood on a tip, a widely used device for quantitative dried-blood microsampling. Curated and supplied on the Humans Nexus platform; Neoteryx is the manufacturer.
A fixed volume,
on a tip.



The Mitra device uses VAMS, volumetric absorptive microsampling. Touch its absorbent tip to a drop of blood on a fingertip and it wicks a fixed volume in seconds (10, 20 or 30&thinsp);µL, the same every time, whatever the hematocrit. You know it’s full when the tip turns fully red; the manufacturer specifies volumetric precision within about 5% (RSD ≤ 5%). The tip then dries, ships at ambient temperature with no cold chain, and needs no centrifugation before the laboratory elutes it and runs the assay. Humans Nexus curates and supplies the device on its platform; Neoteryx is the legal manufacturer.
Where the spot
falls short.
A traditional dried blood spot varies with volume and with hematocrit, which limits quantitation. VAMS captures a fixed volume on each tip, which the manufacturer designs for the reproducibility quantitative assays demand (therapeutic drug monitoring, LC-MS/MS small molecules, and biomarker panels transferred from venous methods).
Touch. Dry. Return.
Touch the tip to a fingertip drop; it wicks a fixed 10–30 µL in seconds and turns fully red when it’s done.
The tip dries on its station, stable at ambient temperature.
Ships by tracked return with no cold chain; the lab elutes and runs the validated assay.
Assembled into a kit.
Mitra is curated onto the platform and assembled into a regulated Humans Nexus collection kit (device, safety lancet, drying station, ambient-stable return packaging and instructions, under its own UDI).

For quantitative work.
Good to know.
How much blood does it take?
A fixed 10, 20 or 30 µL per tip, chosen for the assay (a fraction of a venous tube, from a single finger-prick). The tip absorbs the same volume every time (the manufacturer specifies RSD ≤ 5%), and it turns fully red when it is full, which is what makes the dried sample quantitative.
How is Mitra different from a dried blood spot?
Mitra absorbs a fixed, known volume per tip, which the manufacturer designs to reduce the volume and hematocrit variability that limit traditional dried blood spots, so quantitative assays are more reliable.
What is VAMS best for?
Quantitative work: therapeutic drug monitoring, LC-MS/MS small-molecule assays, and biomarker panels transferred from venous methods. VAMS is widely used in TDM and PK research.
Does it need refrigeration?
No (the dried tip is stable at ambient temperature and ships by standard tracked return, with no cold chain).
Who is the manufacturer?
Neoteryx makes the Mitra device. Humans Nexus curates and supplies it on the platform and assembles the regulated kit around it. Method validation runs per assay before patient-facing reporting.
The complete VAMS evidence base.
Peer-reviewed evidence for volumetric absorptive microsampling (the Mitra format, across both blood and urine) aggregated here and organised by where it is used: immunosuppressant, biologic, oncology and antimicrobial drug monitoring; biomarkers, vitamins and omics; infectious-disease serology; urine steroids and toxicology; and the haematocrit question the format was built to answer. Links open an open-access full text where one exists. This is evidence for the format, not a claim about any specific Humans Nexus assay.
