The summary describes a standard ELISA test kit and its performance characteristics, with no mention of AI or ML technologies in the device description, intended use, or performance studies.

No.
This device is an in vitro diagnostic test used for the detection of autoantibodies to aid in diagnosis, not for treating or preventing disease.

Yes

The "Intended Use / Indications for Use" states that the test kit is "used as an aid in the diagnosis of autoimmune hepatitis, type 2."

No

The device description clearly outlines a physical test kit with components like microwell plates, calibrators, controls, and various solutions, indicating it is a hardware-based in vitro diagnostic device, not software only.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "qualitative detection of IgG class autoantibodies against LKM-1... in human serum and plasma." This indicates it's used to test samples taken from the human body.
  • Device Description: The description details a "microwell ELISA plate," "calibrator," "controls," and various reagents used to perform a test on a biological sample.
  • Performance Studies: The performance studies describe testing "samples" (serum and plasma) and comparing results to a "predicate device," which is a common characteristic of IVD submissions.
  • Key Metrics: The reporting of metrics like Sensitivity and Specificity are standard for evaluating the performance of diagnostic tests.
  • Predicate Device: The mention of a "predicate device" with a K number (K000535) confirms it's being compared to another legally marketed IVD.

All these elements point to the device being used to perform a test in vitro (outside the body) on human specimens to provide information for diagnosis.

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

  • Analytical performance:
    • Precision/Reproducibility: Intra-assay and inter-assay reproducibility were found to be sufficient as no positive sample was found negative and vice versa (except for a single determination of a negative sample that was very close to the cutoff).
    • Analytical specificity: Cross reactivity was investigated using a panel of 28 sera serologically positive for antibodies against SLA/LP. All 28 sera were negative in the Anti-LKM-1 ELISA (IgG), so no cross reactivity is expected. Interference was negligible for hemoglobin (up to 1000 mg/d), triglycerides (up to 2000 mg/dl), and bilirubin (up to 40 mg/dl).
  • Comparison studies:
    • Method comparison with predicate device: A study compared the EUROIMMUN Anti-LKM-1 ELISA (IgG) with an FDA released predicate device using 167 samples (58 from AIH patients, 66 from PBC patients, 15 from AIH/PBC overlap syndrome patients, and 28 from viral hepatitis patients). Additional 29 samples were created by mixing positive and negative samples, resulting in a total of 196 samples.
    • Matrix comparison: The usability of plasma was investigated using 16 sample pairs of serum and corresponding plasma. Passing-Bablok regression was calculated for the comparison of serum to plasma. The 95% C.I. of the slope contained 1.0 and the 95% C.I. of the intercept contained 0, indicating equivalence of concentration between serum and the corresponding plasma matrices. Coefficients of determination were above 0.99 and %BIAS from serum was in the range of 87 to 109 %.
  • Clinical studies:
    • In a clinical/diagnostical study, 515 clinically characterized samples (68 from AIH-2 patients, 65 from AIH-1 patients, 15 from AIH/PBC overlap syndrome patients, and 367 from other control groups) were investigated.
  • Expected values/Reference range: Levels of anti-LKM-1 antibodies (IgG) were analyzed in a panel of 150 apparently healthy blood donors. With a cut-off of ratio 1.0, only one blood donor was found positive.

L. Test Principle:

Patient samples are diluted 1:101 in sample buffer, 100 µl of each diluted patient sample and pre-diluted controls and calibrator are added to the antigen coated microtiter wells and incubated for 30 minutes at room temperature. After incubation the microtiter well strips are washed with wash buffer to remove unbound antibodies and 100 ul of the anti-human IgG enzyme conjugate reagent is added to each microtiter well. After an additional 30-minutes incubation at room temperature, the microtiter wells are again washed 3 times with 300 ul of wash buffer to remove any unbound enzyme conjugate and 100 µl of the chromogen substrate is added. The strips are incubated for 15 minutes at room temperature and 100 µl stop solution is added. The microtiter plates are placed in an ELISA reader and read at a wavelength of 450 nm and a reference wavelength of between 620 nm and 650 nm within 30 minutes.

Performance Characteristics (where applicable): M.

  • Analytical performance: 1.
    • a. Precision/Reproducibility:

The reproducibility of the test was investigated with samples at different points on the calibration curve. Intra-assav reproducibility is based on 20 determinations and inter-assay reproducibility on 24 determinations performed in 6 different runs (days) according to the package insert. Both intra-assay and inter-assay reproducibility were found to be sufficient as no positive sample was found negative and vice versa (except for a single determination of a negative sample that was very close to the cutoff). The following results were obtained:

    Cross-reactivity: Cross reactivity was investigated using a panel of 28 sera serologically positive for antibodies against SLA/LP. All 28 sera were negative in the Anti-LKM-1 ELISA (IgG), so no cross reactivity is expected.

Interference: To investigate the influence from hemoglobin, triglycerides and bilirubin, 5 different specimens at different anti-LKM-1 concentrations (ratio 1.1 - 9.3) were spiked with potential interfering substances and were incubated with the test system. The recovery in relation to the unspiked sample without interferent was calculated. The individual recovery was within the range of 86 - 126%. No significant interference was observed for concentrations of up to 1000 mg/d for hemoglobin, 2000 mg/dl for triglyceride and 40 mg/dl for bilirubin.

A comparison in which the 95% C.I. of the slope contains 1.0 and the 95% C.I. of the intercept contains 0 indicates equivalence of concentration between serum and the corresponding plasma matrices. The comparison above satisfies this condition.

Coefficients of determination were found to be above 0.99 and %BIAS from serum was in the range of 87 to 109 % (serum = 100 %).
