## Indications for Use

The Biophen LMWH Control Kit is a set of control plasmas for the quality control of Low Molecular Weight Heparin (LMWH) measurements, using anti-Xa colorimetric assays. The Biophen LMWH Control Low Kit is a set of control plasmas for the quality control of Low Molecular Weight Heparin (LMWH) measurements, using anti-Xa colorimetric assays. The Biophen UFH Control Kit is a set of control plasmas for the quality control of Low Molecular Weight Heparin (LMWH) measurements, using anti-Xa colorimetric assays. The Biophen UFH Calibrator is a set of calibration plasmas for Unfractionated Heparin (UFH) measurements, using anti-Xa colorimetric assays. The Biophen Heparin Calibrator is a set of calibration plasmas for Heparin (UFH and LMWH) measurements, using anti-Xa colorimetric assays.

## Device Story

Biophen Heparin/UFH Control Plasmas and Calibrators are in vitro diagnostic reagents used in clinical laboratories. Controls assess precision and accuracy of anti-Xa colorimetric assays (e.g., Biophen Heparin 3 & 6); calibrators establish the calibration curve for these assays. The device consists of plasma samples with known heparin concentrations. Laboratory technicians use these to validate assay performance before patient sample testing. By ensuring accurate measurement of heparin levels, the device assists clinicians in monitoring anticoagulant therapy, thereby optimizing therapeutic dosing and minimizing bleeding or clotting risks.

## Clinical Evidence

No clinical data. Bench testing only. Precision/reproducibility studies demonstrated intra-assay %CV ranging from 0.5% to 2.3% across all control and calibrator levels. Traceability established via NIBSC International Standards for LMWH (85/600) and UFH (97/578).

## Technological Characteristics

In vitro diagnostic plasma-based controls and calibrators. Principle of operation: chromogenic anti-Xa assay calibration and quality control. Form factor: liquid/lyophilized plasma. Connectivity: none (standalone reagents).

## Regulatory Identification

A multipurpose system for in vitro coagulation studies is a device consisting of one automated or semiautomated instrument and its associated reagents and controls. The system is used to perform a series of coagulation studies and coagulation factor assays.

## Special Controls

*Classification.* Class II (special controls). A control intended for use with a multipurpose system for in vitro coagulation studies is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.
