The description details a standard immunoassay using competitive binding and a calibration curve. There is no mention of AI/ML algorithms for data analysis, interpretation, or decision-making.
No
This device is an in vitro diagnostic (IVD) assay used to measure folate levels in red blood cells, which aids in the diagnosis and treatment of anemias. It does not directly treat or cure medical conditions.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements obtained by this assay are used in the diagnosis and treatment of anemias."
No
The device description clearly outlines physical components (reagents, calibrators, controls) and their use with immunoassay analyzers, indicating it is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The description explicitly states "in vitro quantitative determination of folate erythrocytes (red blood cells, RBCs)" and "Measurements obtained by this assay are used in the diagnosis and treatment of anemias." This clearly indicates the device is intended for use outside of the body to analyze a biological sample (blood) for diagnostic purposes.
- Device Description: The description details a "binding assay" using "manually prepared hemolysate samples," which are biological samples. The process involves chemical reactions and measurement of analytes within these samples.
- Calibrators and Controls: The inclusion of "Elecsys Folate RBC CalSet" and "Elecsys Folate RBC CalCheck" further confirms its IVD nature. These are standard components of IVD assays used for calibration and quality control.
- Explicit Statement: The description for the Elecsys Folate RBC CalCheck explicitly states "For in vitro diagnostic use."
All of these points align with the definition of an In Vitro Diagnostic device.

Device Description
(1) The Elecsys Folate RBC assay employs a competitive test principle using natural folate binding protein specific for folate. Manually prepared hemolysate samples are used with this assay. Folate in the sample competes with the added folate (labeled with biotin) for the binding sites on folate binding protein (labeled with ruthenium complex). Results are determined via a calibration curve which is instrument-specifically generated by 2-point calibration and a master curve provided via the reagent barcode encoded on the reagent packaging.
(2) The Elecsys Folate RBC CalSet is a lyophilized product consisting of human serum with folate in two concentration ranges. During manufacture, the analyte is spiked into the matrix. This calibrator is used to calibrate the Elecsys Folate RBC assay.
(3) The Elecsys Folate RBC CalCheck is a lyophilized product consisting of a hemolysate with folic acid. During manufacture, the analyte is spiked into the matrix. This solution is used to verify the calibration established with the Elecsys Folate RBC CalSet.

Also includes the following
precautionary statement for high
protein samples:
Samples with extremely high
total protein concentrations (e.g.
patients suffering from
Waldenstrom's
macroglobulinemia) are not
suitable for use in this assay,
since they may lead to the
formation of protein gel in the
assay cup. Processing protein gel
may cause a run abort. The
critical protein concentration is
dependent upon the individual
sample composition and the
sample type. | The assay is unaffected by icterus
(bilirubin Criterion: Recovery within ± 10% of initial value
with samples >5 ng/mL and < +/- 0.5 ng/mL
with samples ≤ 5 ng/mL. In patients receiving therapy with high
biotin doses (i.e. >5 mg/day), no sample
should be taken until at least 8 hours
after the last biotin administration. No interference was observed from
rheumatoid factors up to a concentration
of 1000 IU/mL. In vitro tests were performed on 18
commonly used pharmaceuticals and in
addition on human erythropoietin. No
interference with the assay was found. It is contraindicated to measure samples
of patients receiving therapy with certain
pharmaceuticals, e.g. methotrexate or
leucovorin, because of the cross-
reactivity of folate binding protein with
these compounds. In rare cases, interference due to
extremely high titers of antibodies to
streptavidin and ruthenium can occur. |

Dear Ms. Goodwin:
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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 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.
