BIOSPECIMEN SOURCING
Hard-to-find human biospecimens — we help you source them
For IVD R&D, validation, QC and product development, we match you with currently sourceable human biospecimens, existing sources, or custom collection plans — based on your marker, matrix, target titre or concentration range, volume and quantity requirements.
FEATURED
Featured Biospecimen Sourcing
Below are six categories of high-value human biospecimens we currently prioritize. These samples frequently have specific specification requirements in domestic IVD R&D, QC and product development, and rely more heavily on stable global sourcing, lot matching and cross-border coordination. Available lots and specifications are confirmed per project.

How We Source Biospecimens
From requirement to delivery in four steps. Starting from your project needs, we progressively confirm feasible sources, current specifications and delivery conditions.
Define Requirements
Confirm marker / disease, sample matrix, target titre or concentration range, required volume or sample count, and project purpose.
Sourcing & Feasibility Assessment
Match existing sources or collection pathways through our global sourcing network, and assess project and China import feasibility based on actual sample type, screening status, intended use and documentation requirements.
Confirm Solution & Quote
Verify current source or lot, available quantity, key specifications, testing and documentation, then provide a quote and estimated delivery schedule based on confirmed project conditions.
Lock Source & Deliver
Once the project is confirmed, lock in the corresponding lot or collection arrangement, and coordinate required documentation, import, shipping and final delivery.
Specific lot, titre or concentration, volume, pathogen screening data, COA, pricing and lead time are all subject to actual project confirmation.
OUR NETWORK
Global Sourcing Network
A global sourcing network — not just a product catalogue.
Global Sourcing Network
Connecting professional biospecimen sources and partners across regions to find the most suitable supply pathways for your project.
Logical Biological — Authorized Partner for Mainland China
Providing supply and project support in large-volume serum / plasma, clinical biospecimens, matched sets and project-based collection.
Compliant Import & Documentation Coordination
Confirming source information, screening status, intended use and documentation at the project and lot level, and coordinating China import and delivery pathways.
Specification-Based Customization & Collection
When the existing catalogue does not have an exact match, we can further evaluate target-range screening, prospective collection, pooling and other project-based processing options.
Logical Biological operates a global biospecimen collection network under an ISO 9001:2015 quality management system.
