Intended Use

Trinity Biotech Uni-Gold™ Giardia is a single use rapid immunoassay for the qualitative detection of Giardia lamblia ( G. lamblia ) antigens in human stool specimens. This test is intended for use with patients with gastrointestinal symptoms as an aid in the diagnosis of suspected Giardia gastrointestinal infections. As with other Giardia tests, results should be considered in conjunction with the clinical evaluation and medical history. For In-Vitro Diagnostic use.

Device Description

The Trinity Biotech Uni-Gold™ Giardia was designed as a single use, rapid, lateral flow immunoassay test device to detect the presence of Giardia lamblia antigen in unpreserved (fresh & frozen), preserved and media containing human stool specimens.

The Trinity Biotech Uni-Gold™ Giardia test strip (5mm x 60mm) combines a Nitrocellulose Membrane with designated fiber pads (conjugate, sample and absorbant). The test strip is then placed into a plastic housing and is sealed constituting the Test Device.

The Giardia Nitrocellulose Membrane Test Strip - above consist of

  • A) Mouse anti-Giardia lamblia antibody is coated onto the Test Line region of the test strip.
  • B) Rabbit anti-Goat IgG antibody is coated onto the Control Line region of the Test Strip.
  • C) Goat anti- Giardia lamblia antibodies and Goat IgG antibodies are conjugated to red latex particles and dried onto the inert glass fiber (Conjugate Pad) which is inserted into the test strip below the nitrocellulose zone.

When Giardia antigens are present in the sample they combine with the antibody/red latex complex. As the complex migrates it binds to the antibodies in the test region forming a visible pink/red band. (Picture B) This forms the basis for the double antibody sandwich assay. Excess conjugate forms a second pink/red band in the control region of the device. The control line should always appear as a visible pink/red band in the control region of the device. This internal control line is to ensure and indicate that the test device is functioning correctly.

The plastic housing device contains a window where the diluted stool sample is added (Sample Well) and a window above where the results are read in 15 minutes.

The test concept:

Mouse anti-Giardia lamblia is coated onto the test line region of the nitrocellulose zone of the test strip. Rabbit anti- Goat IgG is coated onto the control line region.

Goat anti-Giardia lamblia antibodies are conjugated to red latex particles and dried onto inert glass fiber. This is inserted into the test strip below the nitrocellulose zone.

A buffered solution is added to a dilution tube followed by the addition of the stool specimen (2 drops) via a disposable pipette. This mixture is then dispensed in total into the sample well of the lateral flow cartridge device with a dropper pipette and migrates through a pad containing red microspheres that have been coated with a antibody specific for the Giardia antigen. If the antigen is present, an immune complex forms. The migration continues along the membrane, which contains a striped down anti Giardia capture antibody. If Giardia antigen is present, the immune complex reacts with the anti-Giardia antibody at the test line on the membrane.

Thus Giardia antigens present in the sample combine with the antibody/red latex. As this complex migrates it binds to the antibodies in the test region forming a visible pink/red band.

Excess conjugate forms a second pink/red band in the control region of the device. The control line should always appear as a visible pink/red band in the control region of the device to indicate that the test device is functioning correctly.

3. Number of Experts and Qualifications for Ground Truth

The document does not explicitly state the "number of experts" used to establish ground truth or their specific qualifications (e.g., "Radiologist with 10 years of experience"). However, the ground truth methods (DFA microscopy, Wheatley's Stain, Iron Hematoxylin Stain) are laboratory diagnostic techniques typically performed by trained medical technologists or laboratory personnel. It implies that these established methods served as the expert-level reference.

4. Adjudication Method for the Test Set

The document does not describe any specific adjudication method (e.g., 2+1, 3+1). The "ground truth" was established by the reference methods (DFA microscopy, Wheatley's Stain, Iron Hematoxylin Stain). In cases where the Uni-Gold device and the initial comparator device disagreed (e.g., in the "Agreement vs. Comparator Device" study), further resolution was sought through DFA microscopy or Iron Hematoxylin Stain, which effectively acted as an adjudicator to determine the true positive/negative status for those discrepant samples.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No multi-reader multi-case (MRMC) comparative effectiveness study was done. The study compares the device performance to established laboratory methods or an existing comparator device, not the improvement of human readers with AI assistance.

6. Standalone (Algorithm Only) Performance

Yes, standalone performance was evaluated. The studies directly compare the Uni-Gold™ Giardia device's results (algorithm only, as it's a rapid immunoassay) against the chosen established ground truth methods (DFA microscopy, non-fluorescent microscopy, or a comparator device). There is no "human-in-the-loop" aspect to the device's reading mechanism described.

7. Type of Ground Truth Used

The types of ground truth used were primarily:

  • DFA Microscopy: Direct Fluorescent Antibody microscopy.
  • Non-Fluorescent Microscopy: Specifically, Wheatley's Stain and Iron Hematoxylin Stain.
  • Comparator Device: Remel Xpect™ Giardia Lateral Flow Assay (510K #: K031942) for initial agreement studies, with discrepant results often adjudicated by DFA or Iron Hematoxylin Stain.

8. Sample Size for the Training Set

The document describes a rapid immunoassay device. It does not mention a "training set" in the context of machine learning. The device is a chemical/immunological test, not an algorithm that requires a training set in the AI sense. The development of the assay itself would have involved internal validation and optimization, but not a distinct "training set" as understood in AI studies.

9. How the Ground Truth for the Training Set Was Established

As there is no "training set" for an AI algorithm, this question is not applicable to the Uni-Gold™ Giardia immunoassay device.

The Trinity Biotech Uni-Gold™ Giardia was designed as a single use, rapid, lateral flow immunoassay test device to detect the presence of Giardia lamblia antigen in unpreserved (fresh & frozen), preserved and media containing human stool specimens.

The Trinity Biotech Uni-Gold™ Giardia test strip (5mm x 60mm) combines a Nitrocellulose Membrane with designated fiber pads (conjugate, sample and absorbant). The test strip is then placed into a plastic housing and is sealed constituting the Test Device.

The plastic housing device contains a window where the diluted stool sample is added (Sample Well) and a window above where the results are read in 15 minutes.

The test concept:

Mouse anti-Giardia lamblia is coated onto the test line region of the nitrocellulose zone of the test strip. Rabbit anti- Goat IgG is coated onto the control line region.

Goat anti-Giardia lamblia antibodies are conjugated to red latex particles and dried onto inert glass fiber. This is inserted into the test strip below the nitrocellulose zone.

Precision /

An Intra-run precision/reproducibility study was performed at 3 sites including one internal site. This study consisted of 6 blind proficiency panel members, varying in reactivity: (2) Low Positive, (2) High Positive and (2) Negative samples. This Reproducibility panel was tested for a period of 5 days. Each site generated 2 runs per day, by two individual technicians totaling 20 replicates per site per panel member, i.e. 12C replicates total. 100% reproducibility was observed for all sites, for all days using the blind panel sample set, therefore 100% of the 120 samples tested for Giardia produced the expected result.

An additional Intra-run precision/reproducibility study was performed internal internally. This study consisted of 12 blind proficiency panel members, varying in reactivity: (4) Low Positive, (4) High Positive and (4) Negative samples. This panel was tested for a period of 5 days. Each site generated 2 runs per day, by two individual technicians totaling 20 replicates per panel member. 100% reproducibility was observed for all days using the blind panel sample set, therefore 100% of the samples tested for Giardia produced the expected result.

The Trinity Biotech Uni-Gold™ Giardia (1206610) along with Uni-Gold™ Giardia Control kit (1206611) was evaluated at 3 external laboratories. A total of 267 retrospective samples were tested side by side on the test device and a commercially available lateral flow device at three external sites in the following stool matrix types: unpreserved frozen (42), C&S (15), SAF (139), and formalin
(71).. The percent agreement of Uni-Gold™ Giardia versus the comparator device was as follows.

§ 866.3220

Entamoeba histolytica serological reagents.(a)
Identification. Entamoeba histolytica serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies toEntamoeba histolytica in serum. Additionally, some of these reagents consist of antisera conjugated with a fluorescent dye (immunofluorescent reagents) used to identifyEntamoeba histolytica directly from clinical specimens. The identification aids in the diagnosis of amebiasis caused by the microscopic protozoan parasiteEntamoeba histolytica and provides epidemiological information on diseases caused by this parasite. The parasite may invade the skin, liver, intestines, lungs, and diaphragm, causing disease conditions such as indolent ulcers, an amebic hepatitis, amebic dysentery, and pulmonary lesions.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.
