No
The device description and performance studies focus on the chemical composition, stability, and traceability of calibrators for an in vitro diagnostic system. There is no mention of AI or ML in the text.
No.
The "Intended Use" states that the device is "for in vitro diagnostic use in the calibration of Lumipulse GLH on the LUMIPULSE G System," which means it is used for testing within a lab setting, not directly for treating a patient.
No
Explanation: This device is a calibrator, which is used to calibrate diagnostic devices, but it is not a diagnostic device itself. The "Intended Use" states it is "for in vitro diagnostic use in the calibration of Lumipulse GLH on the LUMIPULSE G System".
No
The device description clearly states that the device is a kit containing liquid calibrators (bottles of solution) which are physical components, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states: "Lumipulse® GLH Calibrators are for in vitro diagnostic use in the calibration of Lumipulse GLH on the LUMIPULSE G System." This is the primary indicator of an IVD.
- Device Description: The description details the composition of the calibrators, which are reagents used in a laboratory setting to calibrate an analytical instrument (the LUMIPULSE G System) for measuring a specific analyte (luteinizing hormone - LH) in biological samples. This aligns with the nature of IVD devices.
- Intended User / Care Setting: The mention of "in vitro diagnostic use" further reinforces its classification as an IVD, as these devices are used outside of a living organism to diagnose or aid in the diagnosis of a condition.
- Performance Studies: While the performance studies focus on the stability and traceability of the calibrators themselves, this is a crucial aspect of ensuring the accuracy and reliability of the overall diagnostic test performed using the LUMIPULSE G System. The studies are designed to demonstrate that the calibrators are suitable for their intended diagnostic purpose.
- Predicate Device: The mention of a predicate device (K111023; Abbott ARCHITECT® LH Calibrators) which is also a calibrator for an LH assay, further supports the classification as an IVD. Predicate devices are typically other legally marketed IVDs.
In summary, the explicit statement of "in vitro diagnostic use" in the intended use, the nature of the device as a calibrator for a diagnostic system, and the context of its use in a laboratory setting all confirm that this device is an IVD.

Summary of Performance Studies
- Analytical performance:
a. Precision/Reproducibility: Not applicable.
b. Linearity/assav reportable range: Not applicable.
c. Traceability, Stability, Expected values (controls, calibrators, or methods):
Traceability:
The calibrators for use with Lumipulse G LH are prepared gravimetrically and are traceable to the 200 International Standard, 1988 (code: 80/552) provided by the National Institute for Biological Standards and Control (NIBSC).
Value Assignment:
LH Antigen Grade is obtained from CLINIQA. A working stock solution is prepared by dissolving LH antigen in 2-amino-2-hydroxymethyl-1,3-propandiol-based buffer. The working stock solution is assigned a provisional value based on the measurement (6 replicates) using Lumipulse G LH on the LUMIPULSE G system with secondary calibrators. Lumipulse G LH Calibrators are made by calculating the amount of working stock solution and 2-amino-2-hydroxymethyl-1,3-propandiol-based buffer required to achieve the desired 250 mlU/mL calibrator value (Lumipulse G LH Calibrator 2) and adding them together gravimetrically. The 0 mlU/mL calibrator (Lumipulse G LH Calibrator 1) only contains the 2-amino-2-hydroxymethyl-1,3propandiol-based buffer. Lumipulse G LH Calibrator 2 is rate-matched to the respective secondary calibrator based on the measurement in Lumipulse G LH and adjusted if necessary. The measurement of Lumipulse G LH calibrators (10 replicates) and secondary calibrators (10 replicates) are performed on three runs on the LUMIPULSE G system. The mean ratio is the mean counts of the secondary calibrator to the respective Lumipulse G LH calibrator. The acceptable rate mean ratio for the 3 runs is 0.95 – 1.05. This solution is stored at 2 to 10°C.
Stability:
Stability of the calibrators is determined by long-term stability study (Tokyo. Japan) using the LUMIPULSE Forte (f) instrument (only sold in Japan). Intended storage and transport stability study is still on-going (Malvern, PA). Based on real-time stability study the sponsor determined that the calibrators have a shelf-life stability of 12 months when stored at 2-10ºC. The sponsor's protocol and acceptance criteria was reviewed and found to be acceptable.
Note: (The LUMIPULSE f System uses the same Lumipulse G LH Immunoreaction Cartridges and Calibrators as the LUMIPULSE G1200 System).
Studies conducted at Fujirebio, Inc. (Tokyo, Japan):
Shelf-Life Stability:
Three lots of Lumipulse G LH Calibrators were tested on real-time stability with Lumipulse forte (f), a predecessor instrument of LUMIPULSE G1200. LUMIPULSE f and LUMIPULSE G1200 have a confirmed agreement rate.
Three lots of Lumipulse G LH Calibrators were stored at 10℃ for Month 0, 3, 7 and 13 and tested for sensitivity, accuracy and within-run reproducibility.
The results met the criteria for up to 13 months in the 3 lots of Lumipulse G LH Calibrators. Thus it was demonstrated that the LUMIPULSE G LH Calibrators were stable up to 13 months at 10℃ on the LUMIPULSE f System.
Regarding the sensitivity, 0 and 20 mIU/mL LH solutions were tested at each test point in replicates of 3 and the ratio of the amount of the luminescence ("20 mIU/mL" /"0 mIU/mL" LH) were calculated. The criterion was 20 or higher in the ratio.
Regarding the accuracy. 3 samples that ranged 5,850-162,217 mlU/mL were tested . in replicates of 3 at each time point and the ratios of the measured values to the preassigned values were confirmed. The criterion was that the ratios should be within 100 +/- 20% for each replicate.
Regarding within-run reproducibility, 4 samples that ranged 5.850-162.217 mlU/mL were tested in replicates of 6 at each time point. The criterion for the precision was 10% or lower in the CV for each sample.
The shelf life of Lumipulse G LH Calibrators is 12 months at 2 - 10℃.
Transport Conditions:
The transport simulation stability of Lumipulse G LH packed for overseas transport was examined in terms of temperature change.
Temperature change: The Lumipulse G LH Immunoreaction Cartridges, Lumipulse G LH Calibrators, LUMIPULSE G Substrate, LUMIPULSE G Wash Solution and LUMIPULSE G Specimen Diluent 1 were subjected to the following temperature stress: 37 °C 48 +/- 2 hours -> -20 °C 48 +/- 2 hours -> 30 °C 96 +/- 4 hours -> 4 °C 24 +/- 2 hours, according to the stress condition in the internal protocol. Then a visual inspection was carried out for the Lumipulse G LH Cartridges and it was confirmed that they cleared the criteria. Also a sensitivity test and accuracy test were conducted and compared with the intended condition (control). The sensitivity testing was conducted with 0 and 2 mlU/mL LH solutions and the criterion was the ratio of the amount of luminescence ("2 mlU/mL" / "0 mIU/mL" LH) to be 21 or higher. The accuracy testing was conducted with 3 control samples (concentration: 4.1-55.6 mlU/mL with LUMIPULSE G1200) and 4 serum samples (concentration: 11.1-294.0 mlU/mL with LUMIPULSE G1200) in replicates of 1 for control samples and 2 for the serum samples with LUMIPULSE G1200, and the criteria of each value after the stress were 100 +/- 20% of the reference value of each serum sample.
The results of the sensitivity test and accuracy met the criteria. Therefore, the temperature change described above did not affect the performance of Lumipulse G LH using the LUMIPULSE G1200 System.
Lumipulse G LH Calibrators are shipped at 2-10°C.
Studies conducted at Fujirebio Diagnostics, Inc. (Malvern, PA):
Real Time (Intended Storage and Open Use):
In the on-going real-time stability study, the Lumipulse G LH calibrators are stored at 2-10°C. The LH calibrators are tested on one Lumipulse G1200 instrument in duplicate at specified intervals over the shelf life of the device up to the planned shelf life plus one month (13 months).
Real-time intended storage stability is calculated based on the percent difference for the panels at each time point when compared to the value received at Time Point 0 (study initiation). The mean concentration of each panel from each time point must be within ±10% mean concentration at Study Initiation. The % CV value of each panel at each time point must be ≤ 10%. For all 3 lots, Time Point 2 (6 months) was the second time point for testing. The Lumipulse G LH Calibrators were determined to be stable at the intended storage conditions for up to 6 months for all 3 lots.
The testing will continue with this stability protocol until data to support a claim of 12 months is achieved.
Transport Simulation Stability Study:
Transport simulation of the Lumipulse G LH calibrators was examined in terms of temperature. For the temperature test, the calibrators were stored in the following condition: 37 °C 24±2 hours → 25 °C 24±2 hours → -20 °C 24±2 hours → 6 °C 24±2 hours. To determine the impact of temperature on the Lumipulse G LH Calibrators, a performance analysis was conducted.
After each stress condition, all Lumipulse G LH ICs and Lumipulse G LH Calibrators were moved to the next cycle temperature. After all cycles were complete, a visual inspection was performed and the Lumipulse G LH calibrators were stored at the intended storage condition of 2-10°C. Stressed Lumipulse G LH IC's and Calibrators were tested within 3 calendar days after the completion of all cycles. Calibrators were tested in duplicate, controls in replicates of 1 and panels in replicates of 3.
At study initiation, the assay met the acceptance criteria of %CV ≤10% for all transport conditions tested. This stability study is still ongoing.

Also a sensitivity test and accuracy test were conducted and compared with the intended condition (control). The sensitivity testing was conducted with 0 and 2 mlU/mL LH solutions and the criterion was the ratio of the amount of luminescence ("2 mlU/mL" / "0 mIU/mL" LH) to be 21 or higher. The accuracy testing was conducted with 3 control samples (concentration: 4.1-55.6 mlU/mL with LUMIPULSE G1200) and 4 serum samples (concentration: 11.1-294.0 mlU/mL with LUMIPULSE G1200) in replicates of 1 for control samples and 2 for the serum samples with LUMIPULSE G1200, and the criteria of each value after the stress were 100 +/- 20% of the reference value of each serum sample.
The results of the sensitivity test and accuracy met the criteria. Therefore, the temperature change described above did not affect the performance of Lumipulse G LH using the LUMIPULSE G1200 System.

Real Time (Intended Storage and Open Use)
Real-time (Intended Storage and open use) stability is being evaluated as follows: In the on-going real-time stability study, the Lumipulse G LH calibrators are stored at 2-10°C. The LH calibrators are tested on one Lumipulse G1200 instrument in duplicate at specified intervals over the shelf life of the device up to the planned shelf life plus one month (13 months).
Real-time intended storage stability is calculated based on the percent difference for the panels at each time point when compared to the value received at Time Point 0 (study initiation). The mean concentration of each panel from each time point must be within ±10% mean concentration at Study Initiation. The % CV value of each panel at each time point must be ≤ 10%. For all 3 lots, Time Point 2 (6 months) was the second time point for testing. The Lumipulse G LH Calibrators were determined to be stable at the intended storage conditions for up to 6 months for all 3 lots.
The testing will continue with this stability protocol until data to support a claim of 12 months is achieved.

Transport Simulation Stability Study
Transport simulation of the Lumipulse G LH calibrators was examined in terms of temperature. For the temperature test, the calibrators were stored in the following condition: 37 °C 24±2 hours → 25 °C 24±2 hours → -20 °C 24±2 hours → 6 °C 24±2 hours. To determine the impact of temperature on the Lumipulse G LH Calibrators, a performance analysis was conducted.
After each stress condition, all Lumipulse G LH ICs and Lumipulse G LH Calibrators were moved to the next cycle temperature. After all cycles were complete, a visual inspection was performed and the Lumipulse G LH calibrators were stored at the intended storage condition of 2-10°C. Stressed Lumipulse G LH IC's and Calibrators were tested within 3 calendar days after the completion of all cycles. Calibrators were tested in duplicate, controls in replicates of 1 and panels in replicates of 3.
At study initiation, the assay met the acceptance criteria of %CV ≤10% for all transport conditions tested. This stability study is still ongoing.
