TB IgG/IgM Rapid Test Cassette (Colloidal Gold)
Serology-based TB testing remains a documentation-heavy category, where pack configuration and intended-use wording matter as much as the assay format itself.
The TB IgG/IgM Rapid Test Cassette is a Guoke Medical lateral flow immunochromatographic assay, listed under product code GKPD031. It detects IgG and IgM antibodies against Mycobacterium tuberculosis in human whole blood, serum, or plasma.
The manufacturer positions it for professional use as an aid in detecting tuberculosis infection, with results to be read alongside other clinical information. That framing places it in laboratory or clinical workflows rather than self-testing channels.
The assay is qualitative, so it reports presence or absence rather than a measured antibody titre. Sample type flexibility across whole blood, serum, and plasma affects collection logistics and the consumables a site must stock.
Pack norms span 1, 10, 20, 25, 40, and 50 tests per box. Buyers should confirm which configuration is stocked, since box count drives storage footprint, shelf-life planning, and per-test cost calculations.
Documentation is the main pre-purchase checkpoint: regulatory status, language of instructions, storage conditions, shelf life, and certificate of analysis all need confirmation before an order is placed. Minimum order quantity, lead time, and shipping terms should be established in writing.
Because the stated use is adjunctive, the cassette’s operational value depends on how it is embedded in a diagnostic pathway, not on the device alone. Procurement decisions should therefore follow the testing protocol the laboratory or clinic intends to run.
Why it matters:
Confirm intended-use documentation, pack configuration, and storage requirements before committing to volume. A rapid cassette is only as useful as the clinical pathway and paperwork surrounding it.
