Device Description

This 510(k) submission introduces the VITEK®MS PRIME System. The VITEK® MS PRIME is intended for laboratory use by professional users who are trained in microbiology and good laboratory practices.

The VITEK® MS PRIME makes microorganism identifications via matrix-assisted laser desorption/ionization - time of flight mass spectrometry (MALDI-TOF MS) technology, which includes the three basic principles of ionization, separation, and detection,

As a first step, a VITEK® MS-DS Target Slide is prepared in accordance with the instructions for use.

NOTE: Depending on the culture, the analyte sample (i.e. microorganism from cultured media) may be directly spotted to a target slide, or for Mycobacterium. Nocardia and mould it must be processed/inactivated before adding to the target slide.

Once the specimen (cultured from the appropriate media) is spotted to the target slide, a matrix is added for the purpose of easy sublimation and strong absorbance in the laser wavelength employed by theinstrument.

NOTE: The VITEK® MS PRIME is a Class 1 laser product, containing a Class 4 Neodymium-doped yttrium lithium fluoride (Nd:YLF) laser – the laser operates at a wavelength of 349 nm.

The prepared slide is then loaded onto the VITEK®MS PRIME instrument. where a laser targets the sample spot and pulses the isolate spot, resulting in vibrational excitation of matrix and analyte molecules. The matrix transfer protons to the analyte resulting in a positive charge. So as part of the first basic principle, the ionized molecules are then accelerated in an electromagnetic field and a grid electrode in the ionization chamber.

The acceleration in the electromagnetic field is the beginning of the second basic principle (i.e. the separation process that is based of the time-of-flight principle). The velocity of the molecules depends on the mass-to-charge (m/z) ratio of the analyte, with heavier molecules having a higher moment of inertia resulting in a lower velocity.

As a final step in the basic principle of MALDI-ToF technology (i.e. detection) the time of flight is measured precisely by the ions arrival at a particle detector. This speed of the ions in flight depends on their mass - with heavier molecules having a higher moment of inertia resulting in a lower velocity. The time of transit is measured precisely by the ions' arrival at a particle detector. Based on the time of flight, the m/z ratio of each particle can be determined, and a mass spectrum of the analyte sample mixture is generated. The recorded signal is processed and presented as a spectrum of intensity versus mass in Daltons (Da). The mass spectrum displays results as a series of peaks (spectrum) which correspond to the ionized proteins derived from the analyte sample. And for identification of an unknown organism, the resulting mass spectra are sufficiently distinctive to allow taxonomic characterization at the genus and species when compared against the VITEK® MS Knowledge Base.

Biological equivalency study:
Sample size: 1461 samples (487 unique tests in triplicate)

Moulds (97.4% for correct single choice ID or low discrimination to the correct genus)
Nocardia (100% for correct single choice ID or low discrimination to the correct genus).
The VITEK® MS PRIME biological equivalency performance demonstrated an error (i.e. a Discordant Identification) rate of 0.3% (5/1461) with the clinically validated isolates tested. In addition, the combined no identification rate for the VITEK® MS PRIME was 1.6% (23/1461). A minimum 95% agreement (in comparison with the reference method) was met.

Clinical Performance Evaluation:
The clinical performance evaluation for the VITEK®MS PRIME used an equivalency approach with the VITEK® MS - 100 species (with five strains each) from the list of FDA Indications for use for Knowledge Base (KB) v3.2. Performance was determined by comparing the VITEK® MS PRIME identification to a one choice or multiple choice (more than one species) reference identification obtained during previous clinical studies.
Sample size: 500 clinical isolates (100 species with 5 strains each)
Key results:

Overall agreement rate for clinical isolates tested from all sites combined (for correct single choice identification, or a low discrimination correct genus result) was 98.4% (492/500).
Gram positive organisms (99.3% for correct single choice ID or low discrimination to the correct genus)
Gram negative organisms (98.8% for correct single choice ID or low discrimination to the correct genus)
Yeast (95.3% for correct single choice ID or low discrimination to the correct genus)
Mycobacteria (100% for correct single choice ID or low discrimination to the correct genus)
Moulds (98.0% for correct single choice ID or low discrimination to the correct genus)
Nocardia (100% for correct single choice ID or low discrimination to the correct genus).
The VITEK® MS PRIME clinical performance evaluation demonstrated an error (Discordant Identification) rate of 0.4% (2/500) with the clinical isolates tested. In addition, the combined no identification rate for the VITEK® MS PRIME was 1.2% (6/500). A minimum 95% agreement (in comparison with the reference method) was met for overall performance and for each organism group/classification.
When excluding No ID results, performance is 99.6% (492/494) agreement with the same discordant rate of 0.4%.

Challenge Isolate Results:
Sample size: 100 challenge strains
Key results: 100.0% (100/100) agreement. No ID results and no discrepant results were observed.

Quality Control Results:
Key results: 98.3% agreement with all quality control strains tested at all sites.

Reproducibility Results:
Key results: 99.5% agreement for Reproducibility strains tested on the VITEK®MS PRIME.

sample is defined as an average
of 50 spectra obtained by as
many consecutive laser shots. | the laser at the first raster point (five
shots are made to obtain one
profile). If the profile is good, then
the laser will re-shoot the same spot
to acquire a new profile. If there are
two consecutive failed profiles then
the laser moves to the next raster
point. The acquisition process
stops when the target of 100 good
profiles is achieved, or when all
raster points have been visited. |

D. 510(k) Summary:

Intended Use:

VITEK® MS PRIME is a mass spectrometry system using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) for the identification of microorganisms cultured from human specimens.

The VITEK® MS PRIME system is a qualitative in vitro diagnostic device indicated for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of bacterial and fungal infections.
