# From Target Product Profiles (TPPs) to Target Specimen Profiles (TSPs): A New Concept in Infectious Disease Biobanking for Diagnostic Applications

## TL;DR

This paper introduces target specimen profiles (TSPs) to guide biobanks in collecting samples for developing and validating infectious disease diagnostics.

## Contribution

The novel concept of TSPs links specimen collection to diagnostic development goals.

## Key findings

- TSPs define the specimen characteristics needed to meet diagnostic target product profiles.
- Biobanks can use TSPs to prospectively collect sample panels for diagnostics validation.

## Abstract

A target specimen profile (TSP) corresponds to the required characteristics of the specimen panels needed to demonstrate that a diagnostic kit meets the target product profile (TPP). TSPs can guide biobanks in the prospective collection of sample panels to support the development and validation of diagnostics.
