Intended Use
The Mono M Test is a qualitative enzyme immunoassay (EIA) that detects IgM antibodies to Paul-Bunnell heterophil, Epstein-Barr virus capsid antigen (EBV-VCA), and cytomegalovirus (CMV). When used in conjunction with Mono-G Test, it is as an aid in the serodiagnosis of infectious (EBV) mononucleosis and presumptive serodiagnosis of CMV mononucleosis-like syndrome. This assay has not been FDA cleared or approved for the screening of blood or plasma donors. Performance with this device has not been established for either prenatal screening or newborn testing. Performance for this assay has not been established in a non-clinical laboratory environment (e.g., point of care testing).
Device Description
The product is an ELISA test method detecting heterophile, viral capsid antigen and cytomegalovirus IgM antibodies.
More Information

Not Found

No
The document describes a standard enzyme immunoassay (ELISA) test for detecting antibodies. There is no mention of AI, ML, or any computational analysis beyond standard statistical calculations for performance metrics.

No.
The device is described as an enzyme immunoassay (EIA) intended for the serodiagnosis of infectious mononucleosis and presumptive serodiagnosis of CMV mononucleosis-like syndrome, which means it is a diagnostic tool, not a therapeutic one.

Yes

The device is an immunoassay that detects antibodies to aid in the serodiagnosis of infectious mononucleosis and presumptive serodiagnosis of CMV mononucleosis-like syndrome. This clearly indicates its use in identifying or confirming the presence of a disease or condition.

No

The device description clearly states it is an ELISA test method, which is a laboratory-based assay involving physical reagents and procedures, not a software-only device.

Based on the provided text, the device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is a "qualitative enzyme immunoassay (EIA) that detects IgM antibodies..." and is used "as an aid in the serodiagnosis of infectious (EBV) mononucleosis and presumptive serodiagnosis of CMV mononucleosis-like syndrome." This clearly indicates that the device is intended for use in vitro (outside the body) to diagnose or aid in the diagnosis of a disease or condition.
  • Device Description: The "Device Description" further confirms this by stating it is an "ELISA test method detecting heterophile, viral capsid antigen and cytomegalovirus IgM antibodies." ELISA is a common in vitro diagnostic technique.
  • Performance Studies: The description of performance studies involving testing of samples (sera) is consistent with the evaluation of an IVD.

Therefore, the Mono M Test, as described, fits the definition of an In Vitro Diagnostic device.

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

A prospective study was performed to assess assay performance. Site A information based on profile comparison is presented in Table 1. Site B information is shown in Table 2 and the combined data can be seen in Table 3.

Table 1: Site A EBV Performance shows:
ImmunoDOT Negative: 33 (Reference Negative), 0 (Reference Current), 1 (Reference Past/Recent)
ImmunoDOT Current: 2 (Reference Negative), 23 (Reference Current), 1 (Reference Past/Recent)
ImmunoDOT Past/Recent: 0 (Reference Negative), 1 (Reference Current), 112 (Reference Past/Recent)
ImmunoDOT Indeterminate: 0 (Reference Negative), 6 (Reference Current), 7 (Reference Past/Recent)

Table 2: Site B EBV Performance shows:
ImmunoDOT Negative: 9 (Reference Negative), 0 (Reference Current), 0 (Reference Past/Recent)
ImmunoDOT Current: 1 (Reference Negative), 10 (Reference Current), 1 (Reference Past/Recent)
ImmunoDOT Past/Recent: 0 (Reference Negative), 0 (Reference Current), 92 (Reference Past/Recent)
ImmunoDOT Indeterminate: 2 (Reference Negative), 0 (Reference Current), 1 (Reference Past/Recent)

Table 3: EBV Performance Summary shows:
ImmunoDOT Negative: 42 (Reference Negative), 0 (Reference Current), 1 (Reference Past/Recent)
ImmunoDOT Current: 3 (Reference Negative), 33 (Reference Current), 2 (Reference Past/Recent)
ImmunoDOT Past/Recent: 0 (Reference Negative), 1 (Reference Current), 204 (Reference Past/Recent)
ImmunoDOT Indeterminate: 2 (Reference Negative), 6 (Reference Current), 8 (Reference Past/Recent)

There was no toxoplasma IM cases identified during the prospective trial period. Two CMV mononucleosis cases at Site A and three CMV mononucleosis cases at Site B were observed. Three of the five sera from presumptive CMV mononucleosis cases were positive according to reference results. These CMV results are included in Table 4 as ImmunoDOT current positives and summarize overall ImmunoDOT performance.

Table 4: Overall Performance Summary shows:
ImmunoDOT Negative: 42 (Reference Negative), 0 (Reference Current), 1 (Reference Past/Recent)
ImmunoDOT Current: 5 (Reference Negative), 36 (Reference Current), 2 (Reference Past/Recent)
ImmunoDOT Past/Recent: 0 (Reference Negative), 1 (Reference Current), 199 (Reference Past/Recent)
ImmunoDOT Indeterminate: 2 (Reference Negative), 6 (Reference Current), 8 (Reference Past/Recent)

The intensity of the dot is directly related to precision. The darkest dots are most reliable while weaker reactions are proportionately less reliable. Site A and Site B laboratories were supplied masked specimens containing mixtures of the various analytes. Therefore, not all analytes tested the same number of replicates. Testing was conducted in triplicate each day. Tests were performed on six different days. The results are shown below. The results (Tables 12 and 13) show adequate qualitative discrimination for each analyte.

§ 866.3235 Epstein-Barr virus serological reagents.

(a)
Identification. Epstein-Barr virus serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to Epstein-Barr virus in serum. The identification aids in the diagnosis of Epstein-Barr virus infections and provides epidemiological information on diseases caused by these viruses. Epstein-Barr viruses are thought to cause infectious mononucleosis and have been associated with Burkitt's lymphoma (a tumor of the jaw in African children and young adults) and postnasal carcinoma (cancer).(b)
