COVID19 Ag/Ab Sealing Tube Twin Strip
The COVID19 Ag/Ab Sealing Tube Twin Strip from Shanghai Miaoling Biological Engineering Co., Ltd is a lateral flow immunoassay device designed for simultaneous detection of SARS-CoV-2 nucleocapsid antigen and IgG/IgM antibodies in clinical specimens. Each twin strip is sealed within a single tube to prevent cross-contamination, using colloidal gold immunochromatographic membrane technology. The product is intended for in vitro diagnostic use with nasopharyngeal, nasal, saliva, serum, plasma, or fingerstick whole blood samples collected within seven days of symptom onset.
The membrane substrate is standard for rapid diagnostic tests in this category, with gold-conjugated anti-SARS-CoV-2 monoclonal antibodies and capture lines for both antigen and antibody targets. Typical sensitivity and specificity ranges for similar colloidal gold-based dual-detection strips are 85-95% and 92-98% respectively, though exact performance data must be confirmed via validation reports. Packaging is bulk commercial, with strips sealed in individual tubes to maintain sterility and reduce biohazard exposure risk during handling.
This product is primarily purchased by hospitals, private clinics, public health labs, and international distributors supplying point-of-care settings in regions with limited laboratory infrastructure. Buyers commonly request bulk quantities in cartons of 100 or 500 units, with packaging designed for ambient storage and transport. Trade terms are typically FOB Shanghai, with lead times of 10-15 working days after order confirmation. Certification status for CE or FDA clearance is not stated in the listing and must be confirmed directly with the supplier.

Sourcing COVID19 Ag/Ab Sealing Tube Twin Strip from Shanghai Miaoling Biological Engineering Co., Ltd - China Import Guide
Before ordering, verify the supplier provides batch-specific validation reports for sensitivity, specificity, and limit of detection for both antigen and antibody targets. Request the product insert or IFU in English, confirming specimen collection instructions, storage conditions, and interpretation criteria. Ensure the product is not expired and matches the intended use described in your country’s regulatory guidelines for in vitro diagnostics.
Confirm Incoterms with the supplier - commonly FOB Shanghai or CIF to destination port. Lead time is typically 10-15 working days after payment, but may extend during peak demand. Packaging is usually in sealed cartons with individual tube units; ask whether inner packaging includes desiccants or humidity control. Payment terms are typically T/T in advance or LC at sight, but must be negotiated directly.
Perform a pre-shipment inspection to verify seal integrity, correct labeling, and absence of moisture damage. Request a Certificate of Analysis for each batch, including lot number, expiry date, and test results for control lines. Ensure the product complies with your country’s import requirements for medical devices - some jurisdictions require pre-market registration or a CE mark even for non-EU imports.
