  • What is the Tandem M-Pak Total B-HCG Immunoassay used for?

    The Tandem M-Pak Total B-HCG Immunoassay is designed for the qualitative and quantitative detection of total beta-human chorionic gonadotropin (B-HCG) in serum or urine. B-HCG is a key biomarker used in pregnancy testing and monitoring, helping clinicians confirm or evaluate pregnancies by measuring hormone levels.

  • How is the Tandem M-Pak Total B-HCG Immunoassay supplied, and is it single-use?

    The Tandem M-Pak Total B-HCG Immunoassay is supplied as a single-use immunoassay kit. Each kit is intended for one-time use in clinical laboratory settings by trained personnel, ensuring accuracy and preventing cross-contamination between tests.

  • Does the Tandem M-Pak Total B-HCG Immunoassay require special storage conditions?

    No special storage conditions are required beyond standard laboratory practices. The kit should be stored in a way that maintains its integrity, such as at room temperature away from direct light and moisture, but no refrigeration or controlled-environment requirements are specified.

  • Is the Tandem M-Pak Total B-HCG Immunoassay intended for use in MRI environments?

    No, the Tandem M-Pak Total B-HCG Immunoassay is explicitly not intended for use in MRI environments. This is because the kit contains materials that could be affected by magnetic fields, potentially compromising test accuracy or safety.

  • What regulatory approval does the Tandem M-Pak Total B-HCG Immunoassay hold?

    The Tandem M-Pak Total B-HCG Immunoassay holds FDA 510(k) clearance under the reference number K870521. This clearance confirms that the device is substantially equivalent to a legally marketed predicate device and adheres to FDA regulations for pregnancy-related diagnostic assays, classified as a Class II device.
