Peppies Collection QA · Tasso workflow

The Tasso collection device. Your workflow, validated.

Peppies blood events use Tasso blood-collection devices. This track measures an organisation's collection and handling workflow against its selected reference method, sample by sample, and produces a workflow-validation dataset. It does not produce results for anyone's chart.

The Tasso collection device is supplied with Tasso's applicable manufacturer documentation and instructions. Workflow QA is separate from laboratory analysis and never the source of a laboratory report. Reports come solely from the laboratory selected for the order via Labs & Timeline.

Workflow QA subscriptions

Three ways to validate collection

Starter checks the method, Pro powers a parallel comparison study, and the Quality File programme assembles the workflow documentation. Each ships Tasso devices with validation templates — no peptides, no laboratory panels.

Validation workflow

How a dataset is built

Validation is arithmetic before it is evidence. Every plan resolves to a real device count, every draw runs beside an approved method, and every rejection is recorded. The output is a quality file — not a verdict.

Validation matrix
device count = validation events × samples per event
50 Starter · 12 weeks · method check
250 Pro · 24 weeks · powered comparison
100 Quality file · 12 months · evidence build
01

Fix the matrix, not a vague allotment

You commit to a number of validation events and the samples drawn at each. Fifty devices is a method check; two hundred and fifty runs a powered study. The device count is the product of the two — agreed up front, not estimated later.

02

Compare against the approved method

Each Tasso collection runs in parallel with the selected reference collection. We measure agreement, bias and limits against the method that already holds — never the device judged against itself.

03

Characterise sample stability

Time-to-analysis, temperature and handling are logged for every sample. Stability windows are measured, not assumed, so the dataset reflects how the device behaves outside a perfect bench.

04

Track every failure and rejection

Hemolysis, underfill, clotting, mislabelling — rejections are counted and categorised, never quietly dropped. The failure rate is part of the result and travels with the data.

05

Compile a QA file you can hand over

Protocols, raw data, comparison statistics and rejection logs assemble into a single quality file that a laboratory, clinic or QA team can review. The file documents the collection workflow; it does not replace the Tasso device's manufacturer certification.

06

Where the file goes next

A completed dataset documents the organisation's workflow. It is not a laboratory accreditation, a clinical interpretation or permission for Peppies to issue results. The selected laboratory remains responsible for analysis and reporting.

What this track is, and is not

The boundaries below are load-bearing. They are the reason this track can exist alongside research supply and clinical reporting without blurring into either.

Need blood reports? Those are generated only by the laboratory selected for the order — never by the collection device or this QA programme.
