## Indications for Use

The SYNCHRON LX®i 725 System combines the SYNCHRON LX®20 PRO analyzer and the Access® 2 analyzer into a single instrument presentation. Samples are loaded from a single point of entry through a Closed Tube Aliguotter (CTA) unit. The CTA functions as a sample processing manager by aliquotting and routing samples to the Access 2 and/or LX20 PRO analyzer according to programming requirements. The SYNCHRON LX20 PRO is a fully automated, computer-controlled clinical chemistry analyzer intended for the in vitro determination of a variety of general chemistries, therapeutic drugs, and other chemisiries of clinical interest in biological fluids such as serum, plasma, urine, or cerebrospinal fluid, (sample type is chemistry dependent). The Access 2 Immunoassay Analyzer is a microcomputer controlled, random access The analyzer performs enzyme immunoassays utilizing paramagnetic instrument. particle solid phase and chemiluminescent detection. The Access 2 Analyzer is intended for the in vitro determination of a variety of analytes of clinical interest in biological fluids such as serum, plasma, urine, and cerebral spinal fluid, (sample type is chemistry dependent).

## Device Story

The SYNCHRON LXi 725 System is a clinical laboratory analyzer integrating the SYNCHRON LX20 PRO chemistry analyzer and Access 2 immunoassay analyzer. Samples are loaded via a single-point Closed Tube Aliquotter (CTA) module, which identifies, aliquots, and routes samples to the appropriate analytical module. The LX20 PRO performs photometric chemistry analysis; the Access 2 performs enzyme immunoassays using paramagnetic particle solid phase and chemiluminescent detection. A single LX20-based console serves as the user interface for programming, results management, and QC. The system features bar code identification, cap piercing, and obstruction detection. It is operated by laboratory personnel in a clinical setting. The integrated output allows clinicians to receive comprehensive chemistry and immunoassay results from a single sample, facilitating diagnostic decision-making.

## Clinical Evidence

#### 3.0 Device Name(s):

- 3.1 Proprietary Names: SYNCHRON LX®i 725 System
- 3.2 Classification Names: Discrete photometric chemistry analyzer for clinical use [862.2160]

#### 4.0 Legally Marketed Device

The SYNCHRON LXi 725 System claims substantial equivalence to the SYNCHRON LX®20 PRO System currently in commercial distribution (Docket Number K011213).

#### 5.0 Device Description

The SYNCHRON LXi 725 System combines the SYNCHRON LX20 PRO analyzer and Access®2 Immunoassay analyzer into a single instrument presentation. Samples are loaded from a single point of entry through the Closed Tube Aliquoter (CTA) connector unit. The CTA functions as a sample processing manager by aliquotting and routing samples to the Access 2 and/or LX20 PRO modules according to programming requirements. The LX20 PRO and Access 2 systems then deliver samples to the appropriate reaction vessel along with reagents and reaction constituents. The LX20based console functions as the single user interface for managing routine operations such as sample programming, results management, and QC functions.

The LXi system provides analysis of up to 65 analytes per sample, operating in conjunction with the existing reagents, calibrators, and controls designed for use with the LX20 PRO and Access 2 analyzers. The instrument features bar code identification of samples and reagents, Closed Tube Sampling (CTS), and obstruction detection and correction capability. LXi system components include the LX20 PRO analyzer and console, the CTA module, and the Access 2 module and console. The subsystem hardware components for the analytical units include reagent storage compartments, sample and reagent delivery systems, cap piercing assemblies, sample carousels and cranes, hydropneumatics, fluidics, photometric detectors, electronics, and power supplies.

{1}------------------------------------------------

The LXi configuration incorporates the following upgrades to the LX20 PRO System:

#### Closed Tube Aliquotter (CTA) Module 1.

The CTA serves as the connector between the Access 2 and LX20 PRO systems. The CTA module performs sample identification, aliquot preparation, and sample routing to programming requirements. The CTA uses disposable aliquot vessels for Access 2 sampling. The key hardware components include a laser bar code reader, sample rack shuttle, cap piercer, aliquot probe, sample wheel, wash station, and gantry.

#### 2. Access 2 Immunochemistry Module (previously reviewed/cleared under K922823)

The Access 2 analyzer expands the chemistry menu of the LX20 PRO System. An additional serial communications line allows remote control of the Access 2 instrument through the LX20-based console.

# 3. Hardware Modifications

The LX20 PRO sample rack shuttle and instrument covers have been modified to accommodate the CTA and Access 2 modules and to visually integrate the system.

#### Software Modifications ধ,

The LXi System utilizes LX20 operating software version 3.0. Version 3.0 contains the information necessary to configure, order, and report results for Access 2 tests.

#### 6.0 Intended Use

The SYNCHRON LX®i 725 System combines the SYNCHRON LX®20 PRO analyzer and the Access®2 analyzer into a single instrument presentation. Samples are loaded from a single point of entry through a Closed Tube Aliguotter (CTA) unit. The CTA functions as a sample processing manager by aliquotting and routing samples to the Access 2 and/or LX20 PRO analyzer according to programming requirements.

The SYNCHRON LX20 PRO is a fully automated, computer-controlled clinical chemistry analyzer intended for the in vitro determination of a variety of general chemistries, therapeutic drugs, and other chemistries of clinical interest in biological fluids such as serum, plasma, urine, or cerebrospinal fluid. (sample type is chemistry dependent).

The Access 2 Immunoassay Analyzer is a microcomputer controlled, random access instrument. The analyzer performs enzyme immunoassays utilizing paramagnetic particle solid phase and chemiluminescent detection. The Access 2 Analyzer is intended for the in vitro determination of a variety of analytes of clinical interest in biological fluids such as serum, plasma, urine, and cerebral spinal fluid, (sample type is chemistry dependent).

#### 7.0 Comparison to the Predicate

The SYNCHRON LX20 PRO system has been upgraded to an LXi system through 1) modifications to the sample rack shuttle and instrument covers. 2) the addition of a preanalytical CTA unit and an Access 2 Immunoassay analyzer, and, 3) a software update to version 3.0. There is also a name change to LXi 725 System.
