4-in-1 Antibody Test: Registration and Quality Compliance for B2B IVD Supply

Overview

This multi-parameter in-vitro diagnostic cassette gives a qualitative read on antibodies to four infections at once: HIV, HCV, Treponema pallidum (syphilis) and HBV. For distributors and clinic procurement teams, the product's value depends as much on paperwork as on performance. Supply into new markets requires registration, recognized quality certification and lot-level documentation. The compliant path covers CE marking where applicable, an ISO 13485 quality system, GMP manufacturing and a complete registration dossier so the cassette clears customs and passes audit without surprising the buyer after shipment arrives.

How It Works

Each strip uses an immunochromatographic lateral-flow assay. Conjugated antigens capture the corresponding antibody from the sample as it migrates along the membrane, and a visible line appears in the relevant window when that parameter is reactive. The four channels run in parallel from a single applied sample, giving a rapid visual screen that trained staff read within the indicated time window according to the instructions for use, with built-in controls confirming the strip performed correctly.

Indications

• Screening and auxiliary diagnosis of HIV infection
• Screening for HCV, syphilis (Treponema pallidum) and HBV antibodies
• Use on serum, plasma or whole blood per the intended-use statement

Dosage & Administration

Not applicable: this is an in-vitro diagnostic, not a medicine. Follow the instructions for use exactly, add the specified sample volume and buffer, and read the result within the stated window. Results must be interpreted by trained personnel and reported according to local testing algorithms and regulations, with reactive screens sent for confirmation by a reference method before any clinical conclusion is drawn.

Storage & Sourcing

Store at 2 to 30°C in a dry place, sealed in the foil pouch until use. Manufactured in an ISO 13485 and GMP facility with CE marking and lot-specific quality control. Registration dossiers, certificates of analysis and local import licenses support compliant B2B distribution across markets, and the foil pouch protects reagent stability through warm-climate transit when stored as directed.

FAQ

Q: What certifications should a distributor verify?

A: Confirm CE marking where required, an ISO 13485 quality system, GMP manufacturing, and a valid local registration or import license for the target market.

Q: How are lot quality and shelf life controlled?

A: Each lot ships with a certificate of analysis and expiry date; stability data and sealed foil-pouch packaging preserve performance until the stated date.

Q: Is this a confirmatory test?

A: It is a screening and auxiliary tool; reactive results require confirmation by an authorized reference method per national testing algorithms.

Q: What documentation supports B2B procurement?

A: Provide the IFU, SDS, local-language labels, COA and registration certificates so buyers can clear customs and meet audit requirements.
