No
This device is an in vitro diagnostic test kit, meaning it is used for the qualitative or semi-quantitative determination of antibodies to aid in diagnosis, not for treating a condition.
Yes
The "Intended Use / Indications for Use" section explicitly states that the test kit is "used as an aid in the diagnosis of primary biliary cirrhosis (PBC)."
No
The device description clearly outlines a physical test kit with components like microwell plates, calibrators, controls, and reagents, indicating it is a hardware-based 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 or semi-quantitative determination of IgG class autoantibodies against the mitochondrial antigens M2 in human serum and plasma." This involves testing samples taken from the human body in vitro (outside the body).
- Purpose: It is used as an "aid in the diagnosis of primary billary cirrhosis (PBC), in conjunction with other laboratory and clinical findings." This clearly indicates its role in providing diagnostic information based on the analysis of biological samples.
- Device Description: The description details a "microwell ELISA plate coated with M2-3E antigen," "calibrators," "controls," and various reagents used for performing an ELISA test on serum and plasma samples. These are all components typical of an in vitro diagnostic assay.
- Sample Type: The test is performed on "human serum and plasma," which are biological samples taken from a patient.
The definition of an In Vitro Diagnostic (IVD) device is a medical device that is used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening. This device fits that definition perfectly.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Method comparison with predicate device: An external clinical study was performed with 120 clinically characterized samples (39 from AlH patients, 49 from PBC patients and 32 from patients with AIH/PBC overlap syndrome) collected at EUROIMMUN UK Ltd. The samples were tested with the EUROIMMUN Anti-M2-3E ELISA (igG) and with the Inova Quanta Lite M2 EP (MIT3) ELISA as the predicate device. The panel consisted of 18 men and 100 women (2 unknown). The age ranged from 1 - 87 years (2 unknown) with an average age of 50 years. To cover the range around the cut-off with more samples, additional 7 samples with concentrations near the cut-off were created by mixing of positive and negative samples and the results included in the comparison.
Matrix comparison: The usability of plasma was investigated using 21 sample pairs each of serum and corresponding plasma. The samples cover concentrations in the diagnostically important range, i.e. the lower area of the calibration curve and the cut-off. Passing-Bablok regression was calculated for the comparison of serum to plasma. Coefficients of determination were found to be above 0.99 and %BIAS from serum was in the range of 82 to 112 % (serum = 100 %).
Clinical studies: In a clinical study, performed in cooperation with several university hospitals, in total 1180 clinically characterized samples (251 from PBC patients and 929 from control groups) were investigated for anti-mitochondrial antibodies (lgG). The EUROIMMUN Anti-M2-3E ELISA (lgG) showed a sensitivity for PBC of 92.8% and a specificity of 97.4%.

K. Standard/Guidance Document Referenced (if applicable):
None referenced.
L. Test Principle:
Patient samples are diluted 1:101 in sample buffer, 100 µl of each diluted patient sample and pre-diluted controls and calibrators are added to the antigen coated microtiter wells and incubated for 30 minutes at room temperature. After incubation the microtier 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 ul stop solution is added. The microtier 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.
M. Performance Characteristics (where applicable):

- Analytical performance:
- a. Precision/Reproducibility:
The reproducibility of the test was investigated by determining the intra- and inter-assay coefficients of variation (CV) using sera with values at different points on the calibration curve. The intra-assay CVs are based on 20 determinations and the inter-assay CVs on 4 determinations performed on 6 different days. Neither inter-assay variation nor intra-assay variation should show results over CV = 12% for positive samples. The following results were obtained:

b. Linearity/assay reportable range:
The linearity of the test was investigated using serial dilutions of patient sera with high antibody concentrations. Each patient serum was diluted up to 1/32. The dilutions were measured with the Anti-M2-3E ELISA (IgG) according to the package insert in single determinations and the results calculated in RU/ml. The observed/expected (O/E) values in the cut-off were within the specifications (0.8 > O/E > 1.2 - out of specification values are highlighted in grey).

Traceability, Stability, Expected values (controls, calibrators or methods). C.
There is no recognized standard or reference material for anti-mitochondrial antibodies. Arbitrary units are used in the assay.
- Detection limit: d.
The limit of blank is the lowest arbitrary concentration from a replicate series of samples without analyte. It is defined for this assay as a value of three times the standard deviation of the sample buffer. The detection limit of the Anti-M2-3E ELISA (IgG) is 1.1 RU/ml, determined from 20 replicate determinations of sample buffer only. Due to the high dilution factor of the samples, no influence of the sample material (serum or plasma) is expected. The lowest quantified concentration is the lowest calibrator used in the assay (2 RU/ml).
Analytical specificity: e.
Cross-reactivity: The quality of the antigen used and the antigen source a high specificity of the ELISA. Cross reactivity was investigated using a panel of 29 sera serologically positive for antibodies against PCA (n = 10), GBM (n = 10) and LKM (n = 9). All 29 sera were negative in the Anti-M2-3E ELISA (IgG), so no cross reactivity is expected.
4
Interference: To investigate the influence from hemoglobin, triglycerides and bilirubin, 5 different specimens at different anti-M2-3E concentrations (4 - 186 RU/ml) 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 98 - 123 %. No significant interference was observed for concentrations of up to 1000 mg/dl for hemoglobin, 2000 mg/dl for triglyceride and 40 mg/dl for bilirubin.

- Method comparison with predicate device: a.
An external clinical study was performed with 120 clinically characterized samples (39 from AlH patients, 49 from PBC patients and 32 from patients with AIH/PBC overlap syndrome) collected at EUROIMMUN UK Ltd. The samples were tested with the EUROIMMUN Anti-M2-3E ELISA (igG) and with the Inova Quanta Lite M2 EP (MIT3) ELISA as the predicate device. The panel consisted of 18 men and 100 women (2 unknown). The age ranged from 1 - 87 years (2 unknown) with an average age of 50 years. To cover the range around the cut-off with more samples, additional 7 samples with concentrations near the cut-off were created by mixing of positive and negative samples and the results included in the comparison. The results are shown in the table below.
Of the 9 discrepant samples negative in the Inova test and positive in the EUROIMMUN assay, 2 were from patients with AIH/PBC overlap syndrome, 3 were from AIH-1 patients, one from a PBC patient and 3 from an antibody-positive patient diluted with negative material to fit the borderline range. The discrepant sample positive in the Inova test and negative in the EUROIMMUN assay also was a created sample.

b. Matrix comparison:
The usability of plasma was investigated using 21 sample pairs each of serum and corresponding plasma. The samples cover concentrations in the diagnostically important range, i.e. the lower area of the calibration curve and the cut-off. Passing-Bablok regression was calculated for the comparison
of serum to plasma. The results are shown in the table below.
EDTA plasma | Heparin plasma | Citrate plasma | |
---|---|---|---|
Regression equation | |||
(y = plasma, x = serum) | $y = 0.09 + 1.01 x$ | $y = -0.10 + 0.98 x$ | $y = 0.56 + 1.02 x$ |
95% C.I. of intercept | -1.30 - 2.75 | -1.32 - 1.11 | -1.02 - 3.18 |
95% C.I. of slope | 0.98 - 1.04 | 0.96 - 1.01 | 0.98 - 1.06 |
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 comparisons above satisfy this condition.
Coefficients of determination were found to be above 0.99 and %BIAS from serum was in the range of 82 to 112 % (serum = 100 %).
3. Clinical studies:
In a clinical study, performed in cooperation with several university hospitals (see below), in total 1180 clinically characterized samples (251 from PBC patients and 929 from control groups) were investigated for anti-mitochondrial antibodies (lgG). The EUROIMMUN Anti-M2-3E ELISA (lgG) showed a sensitivity for PBC of 92.8% and a specificity of 97.4%. The results are shown in the table below. 95% C.I. are calculated by the exact method.

Dear Ms. Kohl:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must
