Home Sampling

Home sampling: professional lab diagnostics without a practice visit

Home sampling means: the sample is collected at home – and analysed in an ISO 15189-accredited laboratory. That fundamentally sets home sampling apart from rapid tests with self-evaluation: the result is a medically approved lab report, not a test-strip reading. Probatix runs the complete home sampling workflow as a service – from kit dispatch and return logistics through lab analysis to structured result delivery via API.

Sample types & devices

Clinically validated collection – at home

The sample type follows the parameter, not user convenience. These devices and sample types are integrated into the Probatix platform.

Tasso+

Capillary blood, needle-free

Needle-free capillary blood collection from the upper arm via vacuum suction – up to 500 µl, performed by the end user themselves, with high user acceptance.

TAP Micro Select

Capillary blood, one-hand device

Minimally invasive one-hand collection device with a microneedle array and vacuum principle – reproducible sample volumes for laboratory analysis.

Dried Blood Spot (DBS)

Dried capillary blood

Blood drops on a filter card, stable at room temperature for days – the most robust option for postal shipping without a cold chain.

Saliva, urine & stool

Non-invasive sample types

For hormonal questions, metabolic and gut diagnostics – with validated collection sets and return logistics.

Preanalytics & stability

What capillary blood can do – and what it can’t

The honest answer first: capillary blood does not replace every venous blood draw. Many standard parameters – vitamins, thyroid values, blood lipids, HbA1c – are validated for capillary blood and the shipping route. Other parameters are sensitive to haemolysis, sample volume or transport time and belong in a venous workflow or a different sample type.

That is why every programme at Probatix starts with the parameter-to-sample-type mapping: which values should be measured, and which sample type delivers them in stable, validated quality? The preanalytics – collection, storage, shipping – are the biggest source of error in lab diagnostics and are controlled systematically through matched devices, instructions and return logistics.

For telemedicine and digital health teams this means: you don’t get a marketing promise, but a reliable statement per parameter – including the cases where we advise against home sampling.

Logistics chain & fulfillment

From kit dispatch to sample receipt

Probatix handles warehousing, kit assembly, EU-wide shipping with tracking, return logistics and incoming sample control – as an integrated part of the platform, not as an external logistics project.

ISO 15189-accredited labs

Every sample is analysed in accredited partner laboratories – with validated methods, documented preanalytics and medical report approval.

Validated shipping routes

Parameters are only offered if they are validated for the home shipping route – including stability data per sample type and season.

Standardised preanalytics

Instructions, collection devices and return material are matched to each other to control the biggest source of error in lab diagnostics.

Quality metrics

Sample quality, failure rates and turnaround times are recorded systematically – as a steering basis for your programme.

Frequently asked questions

Home sampling: FAQ

The questions CTOs and programme owners ask most often about home sampling.

What is the difference between home sampling and a self-test?

With a self-test, the end user collects the sample and evaluates it themselves – the result is produced at home following rapid-test logic. With home sampling, only the collection happens at home; the analysis takes place in an ISO 15189-accredited specialist laboratory with medical report approval. That is the difference between an unverified quick result and a reliable lab report.

Which values can be measured reliably from capillary blood?

Many standard parameters – such as vitamins, thyroid values, blood lipids or HbA1c – are validated for capillary blood. Not every value can be measured reliably from a few drops, however; some parameters require venous blood or a different sample type. Probatix checks the parameter-to-sample-type mapping per panel and says openly what cannot be measured credibly from capillary blood.

How stable are the samples in postal transit?

That depends on the parameter and the sample type. Dried Blood Spot is stable at room temperature for days; liquid capillary blood is only offered for parameters whose stability is validated for the shipping route. Return logistics are designed for short transit times; sample receipt and quality are monitored systematically.

How quickly is the result available?

For most tests within 48 hours of sample receipt at the lab – plus the shipping time of the sample. Status transitions and report approval are reported to your system in real time via webhook.
