Rapid diagnostic technical services and co-development

Service content

Project screening	Sample type, assay platform, sensitivity target, cost target and production plan are reviewed to prioritize candidate materials and validation steps.
Material selection	Combination evaluation across Ahlstrom materials, fluorescent nanobeads, colloidal gold consumables, membranes, pads, recombinant proteins and paired antibodies.
Sample adoption	Sample delivery, specification confirmation, lot communication, storage conditions and initial application points.
Method validation	Validation points around sensitivity, specificity, background, linear range, repeatability, lot difference and accelerated stability.
Substitution evaluation	Compare domestic or alternative membranes, beads, colloidal gold or raw materials against current imported systems in performance, stability and supply risk.
Process scale-up	Coordinate material lots, packaging, documents and delivery schedule from sample evaluation to pilot or production adoption.

Technical routes

Colloidal gold technical service

Labeling conditions, antigen-antibody pairing, membrane and pad matching, dispensing volume, spraying volume, flow speed, background control and color consistency.

Fluorescence technical service

Bead size and surface group selection, coupling system, fluorescence readout window, strip structure, background control, sensitivity improvement and stability validation.

Raw material evaluation

Reactivity, specificity, signal strength and compatibility evaluation for recombinant proteins, paired antibodies and reagents across assay platforms.

Membrane and pad adoption

Sample pads, conjugate pads, absorbent pads, glass fiber membranes, whole blood filters and backing cards evaluated within the strip structure.

Cooperation models

Sample evaluation	For defined project directions requiring material screening or substitution feasibility confirmation.
Method development support	For R&D prototyping around initial material, label, lateral flow and readout solution setup.
Joint project optimization	For existing strip or kit prototypes with high background, poor release, insufficient sensitivity or lot variation.
Bulk supply coordination	For validated projects entering procurement and production adoption, with specification, lead time, documentation, lot and long-term supply planning.
