Indications for Use

The MDA is a multipurpose system for in vitro coagulation studies and is capable of running various clot based, chromogenic and immunoassays.

Device Story

MDA 180:MDA II is a fully automated, random access analyzer for clinical hemostasis and thrombosis testing. Device measures light transmission changes through reaction mixtures to determine results or reaction rates. System supports traditional clotting, chromogenic, and immunoassays. B.30 software update introduces new methods for OEM chromogenic reagents, new endpoint algorithms to reduce erroneous error rates, a new wash macro for Simplastin HTF to minimize probe precipitate, and a B4 latex method for Free Protein S assay validation. Enhanced waveform analysis features included. Operated by laboratory personnel in clinical settings. Output provides quantitative assay results used by clinicians to assess patient hemostatic status and guide diagnostic/therapeutic decisions.

Clinical Evidence

Bench testing only. Precision data for 12 representative assays met acceptance criteria. 100% agreement observed between B.23 and B.30 software versions across all methods. B.30 demonstrated ability to determine correct clotting times in samples with increased levels of interfering substances. Erroneous result and error rates were improved in B.30 compared to B.23.

Technological Characteristics

Fully automated, random access coagulation analyzer. Uses optical detection (light transmission) for reaction monitoring. Software-controlled fluidics and optics. B.30 software update includes new endpoint algorithms, wash macros, and assay methods. No changes to hardware platform.

Indications for Use

Indicated for in vitro coagulation studies, including clot-based, chromogenic, and immunoassays, for clinical analysis related to hemostasis and thrombosis.

Regulatory Classification

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.

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

The Multi-Channel Discrete Analyzer (MDA) system is a fully automated, random access analyzer used to perform clinical analyses related to hemostasis and thrombosis. The instrument determines results or reaction rates by detecting changes in the light transmitted through a reaction mixture. Flexibility in optics, fluidics, and software allow the MDA to perform many different assays including traditional clotting assays, chromogenic assays, and immunoassays.

The MDA B.30 software version Q08.00 is an update to the MDA B.23 software version Q05.00 and was developed with the same intended use.

The modifications to the MDA B.30 software consists of the following:

- 1. add new methods in order to accommodate new OEM supplied chromogenic reagents:
- new endpoint algorithms to reduce the erroneous error rate 2. without increasing the erroneous result rate;
- 3. new wash macro for Simplastin HTF to minimize precipitate build up in Probe D;
- 4. add a new B4 latex method to allow customers to validate a Free Protein S assay;
- 5. add Italian and Spanish languages; and
- 6. new and enhanced waveform analysis features

#### (a)(5) A statement of the intended use of the device.

#### Device Intended Use:

The MDA is a multipurpose system for in vitro coagulation studies and is capable of running various clot based, chromogenic and immunoassays.

#### (a)(6) A summary of the technological characteristics of the new device in comparison to those of the predicate device.

The data contained in this submission support the claim that the MDA B.30 software is substantially equivalent to the MDA B.23 software in terms of intended use, functional requirements and performance. The MDA instrument platform that contains B.23 software is the exact same instrument platform that contains B.30 software. The operating system, optics, sample type, reagent assays and target population are identical for both versions of software.

### (b)(1) A brief discussion of the nonclinical tests submitted, referenced, or relied on in the Premarket notification submission for a determination of substantial equivalency.

{2}------------------------------------------------

There were no nonclinical tests, referenced or relied on for this submission.

## (b)(2) The conclusions drawn from the nonclinical and clinical tests that demonstrate that the device is as safe, as effective, and performed as well or better than the legally marketed device identified in (a)(3).

Precision data for the 12 representative assays were all well within the criteria stated. There was 100% agreement between the predicate software B.23 and new software version B.30 for all methods. MDA b.30 demonstrated its ability to determine correct clotting times for samples that had increased levels of interfering substances.

The erroneous result rate was much improved in B.30 when compared to B.23. The erroneous error rate was much improved in B.30 when compared to B.23.

Dear Ms. Jennings:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
