No
The description details a standard immunoassay using chemiluminometric technology and a calibration curve. There is no mention of AI, ML, or any related concepts in the device description, performance studies, or key metrics.
No
The device is an in vitro diagnostic assay used to quantify total IgE in serum and plasma, which aids in diagnosis and monitoring but does not provide therapy or treatment.
Yes
The intended use explicitly states "For in vitro diagnostic use in the quantitative determination of total IgE in serum and plasma." This indicates its purpose is to provide information for diagnosis.
No
The device description clearly states it is an immunoassay using direct chemiluminometric technology and is intended for use on the ADVIA Centaur family of analyzers, which are hardware systems.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use".
- Sample Type: The device is intended for use with "serum and plasma (EDTA and lithium heparin)", which are biological specimens tested in vitro (outside the body).
- Measurement: The device performs a "quantitative determination of total IgE", which is a measurement of a substance in a biological sample to aid in diagnosis or monitoring.
- Device Description: The description details a "two-site sandwich immunoassay using direct chemiluminometric technology", which is a common method used in in vitro diagnostic tests.
- Calibration: The use of calibrators and a master curve for generating results is typical for quantitative in vitro diagnostic assays.
- Prescription Use: The "Intended User / Care Setting" indicates "For prescription use only", which is common for IVD devices used in a clinical setting.
- Predicate Device: The mention of a "Predicate Device(s)" with a K number (K920372) indicates that this device is being compared to a previously cleared device, a process common for regulatory clearance of IVDs.
All of these points strongly support the classification of this device as an In Vitro Diagnostic.

Test Principle 11.
The ADVIA Centaur Total IgE (tlgE) assay is a two-site sandwich immunoassay using direct chemiluminometric technology, which uses constant amounts of two antibodies to lgE. The first antibody, in the Lite Reagent, is a goat anti-human IqE antibody labeled with acridinium ester. The second antibody, in the Solid Phase, is a mouse anti-human IgE antibody, which is covalently coupled to paramagnetic particles.

12. Performance Characteristics
The addition of the plasma (EDTA and lithium heparin) sample and detection capability (LoB, LoD, and LoQ) claims in the Instructions for Use (Package Inserts) for the ADVIA Centaur Total IgE (tlgE) assay was demonstrated by testing the performance characteristics with the following studies:
- . Specimen Equivalence by Method Comparison
- . Detection Capability (LoB, LoD, LoQ)
- . Interferences: EDTA and Heparin
The plasma (EDTA and lithium heparin) sample and detection capability (LoB, LoD, and LoQ) claims for the ADVIA Centaur Total IgE (tlgE) assay do not require the collection of additional analytical performance data. Therefore, all analytical performance data previously reviewed for the ADVIA Centaur Total IgE (tlqE) assay continues to apply to this assay, because the assay was not modified.
Detection Limit 12.1
Detection capability was determined in accordance with CLSI Document EP17-A2.
| Limit of Blank (LoB) | 1.5 IU/mL |
|---|---|
| Limit of Detection (LoD) | 2.0 IU/mL |
| Limit of Quantitation (LoQ) | 2.5 IU/mL |
The LoB corresponds to the highest measurement likely to be observed for a blank sample with a probability of 95%.
The LoD corresponds to the lowest concentration of total IgE that can be detected with a probability of 95%.
The LoQ corresponds to the lowest amount of total IgE in a sample at which the within laboratory CV is ≤ 20%.
12.2 Specimen Equivalence by Method Comparison
Specimen equivalency was determined with the weighted Deming linear regression model in accordance with CLSI Document EP09-A3. The following results were obtained:
| Comparison | N* | Sample Interval | Slope
(95% CI) | Intercept
(95% CI) | Correlation
Coefficient (r) |
|--------------------------------------|----|----------------------|-------------------------|--------------------------------|--------------------------------|
| Dipotassium EDTA Plasma

(0.975 - 1.012) | 0.28 IU/mL
(0.086 - 0.475) | 1.00 |
| Lithium Heparin vs. Serum | 73 | 2.80 - 2748.84 IU/mL | 1.00
(0.989 - 1.020) | 0.18 IU/mL
(-0.102 - 0.458) | 1.00 |
- N = Number of samples tested.
The assay is designed to have a slope of 0.90–1.10 for alternate tube types versus serum.

13. Conclusion
The ADVIA Centaur Total IgE (tlgE) assay with the addition of the plasma (EDTA and lithium heparin) sample and new detection capability (LoB, LoD, and LoQ) claims in the Instructions for Use (package insert) is substantially equivalent to the currently marketed ADVIA Centaur Total IgE (tlgE) assay (K920372).
