Overview

AI-generated summary, 20 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

The LISS Reagent is a Media, Potentiating for In Vitro Diagnostic Use, classified under FDA’s 21 CFR 864.9600 regulatory category. It is designed as a low-ionic-strength saline (LISS) solution used to enhance erythrocyte agglutination in hematological testing, improving the sensitivity of blood typing and antibody detection assays. This reagent facilitates the separation and visualization of red blood cell reactions, aiding in the accurate identification of blood group antigens and irregular antibodies. Its primary application lies within hematology diagnostics, where precise agglutination patterns are critical for transfusion compatibility testing.

LISS Reagent is supplied as a sterile, single-use diagnostic media intended for in vitro laboratory use only. It is packaged under controlled conditions to maintain sterility and stability, with no indication of MRI compatibility or reusable design. The product is distributed in sizes and formats aligned with standard hematology workflows, though specific lot sizes or packaging details are not provided in regulatory records. Authorized under FDA 510(k) clearance (K790498) as substantially equivalent to predicate devices, it adheres to 21 CFR 864.9600 for in vitro diagnostic media, with no additional regulatory markings or classifications stated.

Questions

AI-generated answers, 20 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

  • What is the LISS Reagent used for in a clinical setting and why is it important for blood testing?

    The LISS Reagent is specifically designed to enhance erythrocyte agglutination in hematological testing, making it easier to detect blood group antigens and irregular antibodies. By lowering ionic strength, it improves the sensitivity of blood typing and antibody screening assays, which is critical for ensuring accurate transfusion compatibility. This helps clinicians identify potential transfusion reactions or mismatches more reliably.

  • Is the LISS Reagent intended for single-use or repeated use in a laboratory?

    The LISS Reagent is explicitly labeled as a sterile, single-use diagnostic media. It is packaged under controlled conditions to maintain sterility and stability, ensuring it remains safe and effective for one-time use per vial. Reuse is not recommended or supported by the manufacturer.

  • How is the LISS Reagent supplied, and what should I consider when storing it?

    The LISS Reagent is supplied as a sterile, ready-to-use solution in packaging designed for laboratory diagnostics. While exact lot sizes or packaging formats aren’t detailed in the records, it is intended for in vitro use only. Storage should follow standard laboratory protocols for diagnostic media—typically at room temperature, protected from light and contamination, and within the manufacturer’s expiration date. Always check the label for specific storage instructions.

  • What regulatory pathway does the LISS Reagent follow, and what does this mean for its use?

    The LISS Reagent was cleared through the FDA’s 510(k) process (K790498) under 21 CFR 864.9600, classified as a Media, Potentiating for In Vitro Diagnostic Use. This means it was deemed substantially equivalent to predicate devices already on the market, ensuring it meets FDA standards for safety and performance in hematology diagnostics. Clinicians can rely on its regulatory clearance for use in blood typing and antibody detection assays.
