(Used if Part 1 criteria not met). | Not explicitly reported as a separate test, but implied to be met since stability study concluded product maintains optimal performance. |
| Shelf Life Stability | Stable up to 14 months when stored at -20°C prior to opening. | Confirmed by real-time shelf life study. |
| Open Component (In-use) Stability | Stable for 8 hours at ambient or room temperature (15-25°C) after opening. | Confirmed by testing at 2-hourly intervals for up to 9 hours. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size (Test Set):
- Stability Studies: CVM levels (LCOCVM1, LCOCVM2, LCOCVM3, LCOCVM4) run in duplicate (as a minimum) at specified time points (1, 182, 365, 425 days).
- Open Component Testing: Lot 090 CVMs were tested at 2-hourly intervals for up to 9 hours.
- Value Assignment Validation: Six levels of commercially available controls, 25 patient serum samples, 3 spiked normal serum samples, and 5 normal serum samples were used to validate calibrator/CVM value assignments.
- Expected Values/Target Values/Reference Range Establishment: Each CVM level was tested for a total of 27 replicates (9 runs, 3 replicates per run) using 3 different reagent kit lots and 8 IMMULITE 2000 systems.
- Data Provenance: Not explicitly stated (e.g., country of origin). Appears to be based on internal laboratory studies ("Calibrators are not commercialized but are used internally during manufacture and release testing"). The studies are prospective in nature for stability testing.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Not applicable in the context of this device. Ground truth is established through internal gravimetric preparation and reference calibrator curves, with values determined by multiple runs on multiple instruments. There's no mention of human expert interpretation for device performance evaluation.
4. Adjudication Method
- Not applicable. The performance is assessed against predefined numerical acceptance criteria and statistical ranges, not through an adjudication process involving human experts.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- Not applicable. This is a calibration verification material, not a device for human interpretation or diagnosis.
6. Standalone Performance
- Yes, the performance testing described is for the device (IMMULITE® 2000 Cortisol CVM) in a standalone context, as it evaluates the material's stability and value assignment on the IMMULITE 2000 system. It's not an AI algorithm, but the "standalone performance" concept applies in that the material's performance is assessed intrinsically.
7. Type of Ground Truth Used
- Stability and Value Assignment: Traceable to an internal material which has been gravimetrically prepared. CVMs are manufactured using qualified materials and measurement procedures. Dose values are generated from a reference calibrator curve created by assigned reference calibrators, with values averaged across all systems.
- Expected Values/Target Ranges: Established based on the Target Mean and ± 2 Standard Deviation (SD) from extensive testing (27 replicates, 9 runs, 3 replicates/run, 3 kit lots, 8 IMMULITE 2000 systems).
8. Sample Size for the Training Set
- The term "training set" is not directly applicable to a calibration verification material. However, the data used to establish the reference calibrator curve (from which CVM dose values are generated) and the target values are analogous to a training dataset in that they define the expected performance.
- For the reference calibrator curve: Not specified in detail, but it's part of the internal manufacturing and release testing of Cortisol reagents and two-point adjustors.
- For CVM Target Values: Each CVM level was tested for a total of 27 replicates (9 runs, 3 replicates per run) using 3 different reagent kit lots and 8 IMMULITE 2000 systems to establish the target mean and SD.
9. How the Ground Truth for the Training Set Was Established
- Reference Calibrator Curve: The CVMs are "value assigned using assigned reference calibrators." These calibrators are internally used during manufacture and release testing. The CVMs' dose values are generated using the curve established by these assigned reference calibrators. The underlying ground truth for these reference calibrators is based on gravimetric preparation and qualified measurement procedures.
- CVM Target Values: Established through extensive testing on multiple systems and reagent lots, calculating the mean and standard deviation from these empirical measurements, and then applying a 95% confidence interval ($\pm 2SD$).

7. Non-Clinical Performance Testing
Performance testing has been carried out to demonstrate that this device meets the performance specifications for its intend use. The following tests were performed on the candidate device.
Stability Summary:
The stability study was conducted to validate real-time shelf life and open component (in-use or open vial) claim for the IMMULITE 2000 Cortisol Calibration Material (CVM) to ensure that it maintains optimal product performance on IMMULITE 2000 platforms throughout the established shelf life of the CVM. The Calibration Verification Materials are stable up to 14 months when stored at -20°C prior to opening and stable for 8 hours at ambient or room temperature (15-25°C) after opening.
{2}------------------------------------------------
Stability Protocol Summary:
The CVM study protocols are run as part of the calibrator stability testing. The stability calibrators/CVMs are run in duplicate (as a minimum) at the time points shown in Table 2, and the dose value is determined from the reference calibrator curve.
| CVM Level | Time-Points(Days) | |||
|---|---|---|---|---|
| LCOCVM1 | 1 | 182 | 365 | 425 |
| LCOCVM2 | 1 | 182 | 365 | 425 |

| LCOCVM4 | 1 | 182 | 365 | 425 |
Table 2: Stability Protocol Summary
For Open Component testing, the results were determined from a 2-point adjustment. Using IMMULITE 2000 Cortisol (L2KCO) kit lot 362, lot 090 CVMs were tested at 2-hourly intervals for up to 9 hours at ambient or room temperature (15-25°C) conditions.
Stability Acceptance Criteria Summary:
The Acceptance Criteria for the Cortisol Calibration Verification Material (CVM) are in 2 parts. Part 1 consists of guideline acceptance criteria which require dose value of stability
calibrators/CVM to fall between ±20% of assigned dose for CVM level 2, ±15% of assigned dose for level 3 and ±19% of assigned dose for level 4. Part 2 review limits criteria which require dose value of the controls to be within 2 Standard Deviations (SD) of the control target value when generated from the stability calibrator curve. If the result is not within acceptable dose range of ±20% for level 2, ±15% of assigned dose for level 3 and within ±19% of assigned dose for level 4, then additional data review is conducted using part 2 criteria.
Traceability:
The IMMULITE Cortisol CVMs are traceable to an internal material which has been gravimetrically prepared. The CVMs are manufactured using qualified materials and measurement procedures.
Value Assignment:
The IMMULITE Cortisol CVMs are 4 level materials which are a subset of 8 level Cortisol calibrators. Calibrators are not commercialized but are used internally during manufacture and release testing of Cortisol reagents and two point adjustors. The IMMULITE calibrators and therefore CVMs are value assigned using assigned reference calibrators. The CVMs are manufactured using qualified materials and measurement procedures. The CVMs dose values are generated using curve generated by assigned reference calibrators. The CVM values are calculated based on the recovered values for each run on each instrument independently. CVM values are then averaged across all systems. Quality control is performed by calculating the recovery of patient samples, spiked patient samples and controls using the assigned CVM values. Six levels of commercially available controls and 25 patient serum samples, 3 spiked normal serum samples and 5 normal serum samples were used to validate calibrator/CVM value assignments.
{3}------------------------------------------------
Expected Values/Target Values/Reference Range:
Each CVM level was tested for a total of 27 replicates; 9 runs and 3 replicates per run, 3 different reagent kit lots and 8 IMMULITE 2000 systems. The Guideline Range (95% confidence interval) for each CVM level was established based on the Target Mean and ± 2 Standard Deviation (SD). The target values are provided in the IMMULITE® 2000 CVM Calibration Material lotspecific value card. The expected assay range is 1 to 50 g/dL. The target values in Table 3 can be considered as guidelines.
| Analyte targetlevels | CVM Level | *TargetMeang/dL) | StandardDeviation(SD) | Guideline ±2SDRange | |
|---|---|---|---|---|---|
| LCOCVM1 | 0.00 | - | 0. | 1.0 | |
| LCOCVM2 | 4.54 | 0.455 | 3. | 5.45 | |
| LCOCVM3 | 18.7 | 1.4 | 15 | 21.5 | |
| LCOCVM4 | 54.5 | 5.2 | 44 | 64.9 | |
| Assay Range | 1 to 50 g/dL |
Table 3: Analyte Target Range Values
*Note: when CVMs are run by the customer, an actual value below and above the assay range will result when the customer programs the CVMs as calibration verifiers in the instrument software. If programmed as a patient or control, then the software will give values as < or > the assay lower and upper range.
Each laboratory should establish their limits for acceptability based on methodology, clinical significance and medical decision levels of the test analyte. The representative, total precision tabulated in the respective assay instructions for use may be considered as one factor when establishing local, acceptable ranges. The values provided above may be considered as guidelines. Value assignment is lot specific.

Table 2: Stability Protocol Summary
For Open Component testing, the results were determined from a 2-point adjustment. Using IMMULITE 2000 Folic Acid (L2KFO) kit lot 446, lot 090B Folic Acid CVMs were tested at 2hourly intervals for up to 9 hours at ambient or room temperature (15-25°C) conditions.
Stability Acceptance Criteria Summary:
The Acceptance Criteria for the IMMULITE Folic Acid Calibration Verification Material (CVM) are in 2 parts. Part 1 consists of guideline acceptance criteria which require dose value of stability CVMs to fall between ±15% of the assigned dose for CVM level 2, within ±10% of the assigned dose for level 3 and within ±12% of assigned dose for CVM level 4. Part 2 review limits criteria which require dose value of the controls to be within 2 Standard Deviations (SD) of the control target value when generated from the stability calibrator curve. If the result is not within acceptable dose range of ±15% of the assigned dose for CVM level 2, within ±10% of the assigned dose for level 3 and within ±12% of assigned dose for CVM level 4 then additional data review is conducted using part 2 criteria.
Traceability:
The IMMULITE Folic Acid CVMs are traceable to an internal material which has been gravimetrically prepared. The CVMs are manufactured using qualified materials and measurement procedures.
Value Assignment:
The IMMULITE Folic Acid CVMs are 4 level materials which are a subset of 8 level Folic Acid calibrators. Calibrators are not commercialized but are used internally during manufacture and release testing of Folic Acid reagents and two point adjustors. The IMMULITE calibrators and therefore CVMs are value assigned using assigned reference calibrators. The CVMs dose values are generated using curve generated by assigned reference calibrators. The CVM values are calculated based on the recovered values for each run on each instrument independently. The CVM values are then averaged across all systems. Quality control is performed by calculating the recovery of patient samples and controls using the assigned CVM values. The controls must fall within their target ranges. Six levels of commercially available controls and 14 patient serum samples were used to validate calibrator/CVM value assignments.
Expected Values/Target Values/Reference Range:
The CVMs are manufactured using qualified materials and measurement procedures. The Folic Acid CVMs were tested on 27 replicates in total comprised of 9 runs and 3 replicates per run on 6 IMMULITE 2000 systems and 3 different reagent kit lots. The CVMs dose values are generated using curve generated by assigned reference calibrators. The CVM values are calculated based on the recovered values for each run on each instrument independently. The CVM values are then averaged across all systems. Quality control is performed by calculating the recovery of patient samples and controls using the assigned CVM values. The Guideline Range (95% confidence interval) for each CVM level was established based on the Target Mean and ± 2 Standard Deviation (SD). The expected assay range is 1 to 24 ng/mL. The target values in Table 3 can be considered as guidelines.

*Note: when CVMs are run by the customer, an actual value below and above the assay range will result when the customer programs the CVMs as calibration verifiers in the instrument software. If programmed as a patient or control, then the software will give values as < or > the assay lower and upper range.
Each laboratory should establish their limits for acceptability based on methodology, clinical significance and medical decision levels of the test analyte. The representative, total precision tabulated in the respective assay instructions for use may be considered as one factor when establishing local, acceptable ranges. The values provided above may be considered as guidelines. Value assignment is lot specific.
