Hbsag test strip price manufacturers

When sourcing HBsAg (Hepatitis B Surface Antigen) test strips, you must prioritize Diagnostic Sensitivity (typically ≥99%) and Diagnostic Specificity (typically ≥99%) to ensure accurate results. The Analytical Sensitivity (LOD - Limit of Detection) is crucial; high-quality strips should detect HBsAg levels as low as 0.5 ng/mL or 1 IU/mL. Additionally, verify the specimen type compatibility, as some strips are designed for whole blood, serum, or plasma, while others are universal.

As a medical diagnostic product, HBsAg test strips must adhere to strict regulatory frameworks. Ensure the manufacturer holds ISO 13485 certification for medical device quality management. For the European market, CE Marking (IVDD or IVDR compliance) is mandatory. For the U.S. market, FDA 510(k) clearance is required. Additionally, check for WHO Prequalification (WHO PQ) if the products are intended for international aid or government tenders.

Standard HBsAg test strips usually offer a shelf life of 18 to 24 months when stored at 2°C to 30°C. You should request desiccant-sealed aluminum foil pouches for individual strips to prevent moisture degradation. For B2B buyers, sourcing in bulk formats (e.g., 50 or 100 tests per box) can reduce the unit price by 15-25% compared to single-test retail packaging.

The price is primarily driven by order volume (MOQ), the format (strip vs. cassette), and the technological platform (Colloidal Gold vs. Fluorescence Immunochromatography). Cassettes are generally more expensive than strips due to the plastic housing but offer easier handling. Buyers can often negotiate a lower unit price (ranging from $0.05 to $0.30 USD) by committing to annual volumes or choosing OEM/Private Label options where the supplier provides neutral packaging.

Always conduct a Supplier Audit via Made-in-China.com to verify the supplier's 'Audited Supplier' status. Request a Batch Release Certificate (BRC) and a Certificate of Analysis (COA) for every shipment. It is highly recommended to order a small sample batch (e.g., 100 tests) to perform independent lab validation before placing a full-scale container order.

Medical rapid tests are temperature-sensitive. You must ensure the logistics provider uses temperature-controlled shipping (Cold Chain) if the transit route passes through extreme heat zones. For standard air freight, ensure the master cartons are double-walled corrugated fiberboard and marked with 'Keep Dry' and 'Store Between 2-30°C' symbols to prevent protein denaturation in the test reagents.

Ensure the HS Code (typically 3822.19) is correctly declared on all commercial invoices. You must provide the Import License required by your local Ministry of Health. Failure to provide a Declaration of Conformity or the correct Product Registration Certificate can lead to immediate seizure of the goods by customs authorities.

Use Secured Payment services provided by Made-in-China.com to ensure funds are only released after the shipping documents are verified. For large orders, consider a Letter of Credit (L/C) or a 30% deposit / 70% balance against the Bill of Lading (B/L) to maintain leverage over quality and delivery timelines.
