No
The document describes a standard photo-optical instrument for clotting tests and does not mention any AI or ML components or capabilities.
No.
The device is described as an "in-vitro diagnostic" instrument used for clotting tests of plasma samples, which means it analyzes samples outside of a living organism to diagnose conditions, rather than directly treating or preventing disease within a living being.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "an in-vitro diagnostic clotting testing" instrument and is used for "performance of in-vitro diagnostic clotting testing."
No
The device description explicitly states it is a "photo-optical instrument" and details hardware components like a light source (photodiode) and an incubator block. This indicates it is a physical device, not software only.
Yes, based on the provided information, the Fibron-1 is an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use/Indications for Use: Explicitly states it is used for "in-vitro diagnostic clotting testing of citrated plasma samples in the clinical laboratory."
- Device Description: Reinforces its use for "in-vitro diagnostic clotting testing."
- Clinical Laboratory Setting: The intended user and care setting is the "Clinical laboratory," which is a typical environment for IVD testing.
- Testing of Biological Samples: It tests "citrated plasma samples," which are biological specimens.
- Diagnostic Purpose: The tests performed (PT and APTT) are standard diagnostic tests used to assess blood clotting function.
All these points align with the definition and characteristics of an In Vitro Diagnostic device.

Device Name:
Fibron-1 (Coagulation Instrument).
Common Name:
Coagulation Instrument
Classification Name:
Coagulation Instrument has been classified as Class II device. 21 CFR 864.5400 (Product Code KQG). This device is intended for clinical use in conjunction with certain materials to measure a clot formation.
Description of the Fibron-1
The Fibron-1 is a photo-optical instrument used for the performance of in-vitro diagnostic clotting testing of citrated plasma samples in the clinical laboratory. The instrument utilizes photo-optical principles for clot detection. The light source is a high intensity photodiode. The incubator block is temperature regulated to 36.5 - 37.5℃ and contains four measuring positions, 4 reagent and 4 cuvette pre-warming positions.

Intended Use
The Fibron-1 is a photo-optical instrument used for the performance of in-vitro diagnostic clotting testing of citrated plasma samples in the clinical laboratory. The Fibrin-1, which uses clot formation as an endpoint, may be used for the performance of the Prothrombin Time Test (PT) and the Activated Partial Thromboplastin Test (APTT).
Substantial Equivalence:
The Fibron-1 is comparable to the MLA-900C (K884863) and the ACL 100 (K881367). The instruments have a similar intended use for in-vitro diagnostic coagulation testing in the clinical laboratory. Further, the proposed device and the predicate devices utilize photo-optical measurement principles for clot detection. The Fibron-1 is also typical of photo-optical coagulation systems in general.
Fibron-1 is a "manual" coagulation instrument, in that the user must pipettes both sample and test reagent. In contrast, the MLA-900C is semi-automated which requires manual sample addition, but has an automatic pipette for reagent addition. The light source for the MLA instruments is a halogen lamp and the wavelenath is set at 550 nm for clotting assays. An LED at 620 nm is used by the Fibron-1. Although the Fibron-1 uses a different wavelength for clotting assays compared to the MLA, it has been optimized for this specific light source. The performance data generated support this statement.
Comparison instrument testing was performed in-house and at a community hospital and the results are shown in Tables 1 and 2. Specimens were evaluated from healthy individuals and from patients with different pathological conditions, which are expected to affect the results for a particular assay. Clotting time ranged from 10 to 39 seconds.

Image /page/2/Figure/0 description: The image contains a table and a scatter plot. The table shows the instrument, parameter, slope, intercept, and correlation for Fibron-1 vs ACL 100 for clotting time and INR. For clotting time, the slope is 1.24, the intercept is -2.46, and the correlation is 0.972. The scatter plot shows the correlation between Fibron PT clotting times and ACL 100 PT clotting times, with a correlation of 0.972.

The data for precision and accuracy demonstrate general agreement with levels that are comparable to other systems approved for marketing commercially in the United States. The data demonstrate positive correlation and substantial equivalence.
The Fibron-1 operates in the normal laboratory environment. The product does not support or sustain life and does not present a reasonable risk of illness or injury. When procedures found in the Operations Manual are followed the device is safe in general laboratory use.
Vital Scientific NV, concludes that the Fibron-1 has a similar intended use, technological characteristics and combined performance data which support the statement that the Fibron-1 is substantially equivalent to the predicate device.

Dear Dr. Stein:
Re:
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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
6
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588.
