Intended Use
The Emit® Caffeine Assay is a homogeneous enzyme immunoassay intended for use in the quantitative analysis of caffeine levels in human serum in subjects undergoing therapy with caffeine, especially in cases of neonatal apnea.
Device Description
The Emit® Caffeine Assay is a homogeneous enzyme immunoassay technique used for the analysis of specific compounds in biological fluids. The assay is based on competition between drug in the sample and drug labeled with the enzyme glucose-6-phosphate deyhdrogenase (G6PDH) for antibody binding sites. Enzyme activity decreases upon binding to the antibody, so the drug concentration in the sample can be measured in terms of enzyme activity. Active enzyme converts oxidized nicotinamide adenine dinucleotide (NAD) to NADH. resulting in an absorbance change that can be measured spectrophotometrically.
More Information

Not Found

No
The device description details a standard enzyme immunoassay based on chemical reactions and spectrophotometric measurement. There is no mention of AI, ML, or any computational algorithms beyond basic data processing for absorbance measurements. The performance study compares the assay results to HPLC, a traditional analytical method, further indicating the absence of AI/ML.

No
The device is used for quantitative analysis of caffeine levels, which aids in monitoring therapy but does not directly provide therapeutic benefits or treat a disease.

Yes

The device quantifies caffeine levels in human serum to assist in managing therapy, which directly supports diagnosis and monitoring of patient conditions.

No

The device description clearly outlines a homogeneous enzyme immunoassay technique involving chemical reactions, enzyme activity measurement, and spectrophotometric analysis, which are all hardware-dependent processes.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative analysis of caffeine levels in human serum." This involves testing a biological sample (human serum) outside of the body to provide information about a patient's health status (caffeine levels in this case).
  • Device Description: The description details a "homogeneous enzyme immunoassay technique used for the analysis of specific compounds in biological fluids." This is a common method used in IVD devices to measure substances in samples like serum.
  • Sample Type: The assay is performed on "human serum," which is a biological fluid.
  • Performance Study: The performance study involves testing "neonate samples" and comparing the results to another analytical method (HPLC). This is typical for validating the performance of an IVD device.

All of these characteristics align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or screening purposes.

To support the broader intended use, a method comparison study was performed using 110 neonate samples with values spanning the assay range. Of these samples, thirty-one (31) were from patients who had received Theophylline and 79 were from patients who had received with Caffeine. The Assay results were compared to HPLC.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The modified Emit® Caffeine Assay has a broader intended use than the currently cleared Emit® Caffeine Assay to include measurement of caffeine as a parent drug. The use of the current Emit® Caffeine Assav is limited to measurement of caffeine as a metabolite of Theophylline. To support the broader intended use, a method comparison study was performed using 110 neonate samples with values spanning the assay range. The Emit® Caffeine Assay had excellent correlation with HPLC (correlation coefficient=0.99). Other performance characteristics of the Emit® Caffeine Assay were previously established under K853872.
