Intended Use
• Elecsys Vitamin D Reagent: The Elecsys Vitamin D assay is intended for the quantitative determination of total 25-hydroxyvitamin D in human serum and plasma. The assay is to be used as an aid in the assessment of vitamin D sufficiency in adults. The electrochemiluminescence binding assay is intended for use on Elecsys and cobas e immunoassay analyzers. • Elecsys Vitamin D CalSet: Elecsys Vitamin D CalSet is used for calibrating the quantitative Elecsys Vitamin D assay on the Elecsys and cobas e immunoassay analyzers. • Elecsys PreciControl Varia 3: Elecsys PreciControl Varia 3 is used for quality control of the specified Elecsys immunoassays on the Elecsys and cobas e immunoassay analyzers. • Elecsys Vitamin D CalCheck 5: The Elecsys Vitamin D CalCheck 5 is an assayed control for use in calibration verification and for use in the verification of the assay range established by the Elecsys Vitamin D reagent on the indicated Elecsys and cobas e immunoassay analyzers.
Device Description
(1) The Elecsys Vitamin D Assay is a competitive protein binding assay which uses Vitamin D Binding Protein instead of monoclonal antibodies for detection of 25-Hydroxyvitamin D. The total duration of the assay is 27 minutes. The sample is treated with pretreatment reagent in the first incubation period. This releases any vitamin D from the endogenous vitamin D binding protein present in the patient's sample. In the next incubation, vitamin D binding protein labeled with ruthenium is added and a complex is formed between the vitamin D (25-OH) and the ruthenylated vitamin D binding protein. In the 30 and final incubation, streptavidin-coated microparticles are added along with vitamin D (25-OH) labeled with biotin. Any unbound ruthenium labeled vitamin D binding proteins become occupied with biotin-labeled vitamin D (25-OH). The complex consisting of the ruthenylated vitamin D binding protein and the biotinylated vitamin D (25-OH) becomes bound to the solid phase via interaction of the biotin and streptavidin. The reaction mixture is aspirated into the measuring cell where the electrochemiluminescence emission is detected. Results are determined using a calibration curve that is generated specifically on each instrument by a 2 point calibration provided with the reagent bar code. (2) The Elecsys Vitamin D CalSet is a lyophilized product based on human serum. It has been standardized against LC-MS/MS, which has in turn been standardized to the NIST standard. . (3) The Elecsys PreciControl Varia 3 is a multi-composite lyophilized 3 level control set which has been previously cleared for 7 components . The Elecsys PreciControl Varia 3 has been cleared under K111506 for the following analytes: Vitamin B12, Ferritin, Folate III, betaCrossLaps/Serum (-CTx), Osteocalcin, Parathyroid Hormone, Parathyroid Hormone Short Turnaround Time (PTH-STAT). (4) The Elecsys Vitamin D CalCheck 5 contains 5 lyophilized levels based on human serum.
More Information

No reference device K/DEN numbers were found in the text. The section for "Reference Device(s)" states "Not Found".

No
The device description details a standard electrochemiluminescence immunoassay and associated reagents and controls. There is no mention of AI or ML in the intended use, device description, or performance studies.

No.
The device is an in-vitro diagnostic assay and associated reagents used to measure 25-hydroxyvitamin D levels, which aids in assessing vitamin D sufficiency. It is not used for treating or preventing diseases.

Yes

The intended use explicitly states: "The assay is to be used as an aid in the assessment of vitamin D sufficiency in adults." This indicates the device provides information for making a clinical determination.

No

The device description clearly outlines a competitive protein binding assay using reagents, calibrators, and controls, intended for use on Elecsys and cobas e immunoassay analyzers. This involves physical components and chemical reactions, not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the Elecsys Vitamin D assay is for the "quantitative determination of total 25-hydroxyvitamin D in human serum and plasma." This is a measurement performed in vitro (outside the body) on biological samples.
  • Aid in Assessment: The assay is used as an "aid in the assessment of vitamin D sufficiency in adults." This indicates its use in a clinical context to provide information for diagnosis or assessment of a health condition.
  • Device Description: The description details a laboratory-based assay using reagents, calibrators, and controls to measure an analyte in a biological sample. This is characteristic of an IVD.
  • Components: The components listed (reagent, calibrator, control) are all typical components of an IVD system used for laboratory testing.
  • Performance Studies: The inclusion of method comparison studies against other assays (LC-MS/MS and Abbott) and analytical sensitivity metrics (LoB, LoD, LoQ) are standard for demonstrating the performance of an IVD.
  • Predicate Devices: The listing of predicate devices, which are also IVDs (assays, calibrators, controls), further confirms the classification of this device as an IVD.

In summary, the device is designed to perform a test on biological samples in vitro to provide information for clinical assessment, which is the definition of an In Vitro Diagnostic device.
