Intended Use
The QuickVue Advance pH and Amines gll test contains two colorimetric tests intended for the qualitative detection of elevated vaginal fluid pH (pH ≥ 4.7) and the presence of volatile vaginal fluid amines. The test is intended for use by health care professionals as an aid in the diagnosis of bacterial vaginosis.
Device Description
The QuickVue Advance pH and Amines gll test contains two qualitative, colorimetric tests for use in the characterization of a vaginal fluid sample: (1) a pH test that differentiates vaqinal fluid pH < 4.7 from vaginal fluid pH > 4.7; and (2) a test that detects alkali volatilizable amines in vaginal fluid. The test is intended for use by health care professionals as an aid in the diagnosis of bacterial vaginosis.

No
The device description and performance studies focus on colorimetric tests and traditional analytical methods, with no mention of AI or ML terms or concepts.

No
The device is described as an aid in diagnosis and does not include any therapeutic treatment or intervention.

Yes
The "Intended Use / Indications for Use" section explicitly states that the test is "intended for use by health care professionals as an aid in the diagnosis of bacterial vaginosis." This directly indicates its diagnostic purpose.

No

The device description clearly indicates it is a "colorimetric test" and describes physical components and chemical reactions for detecting pH and amines in vaginal fluid. This is a physical diagnostic test, not a software-only device.

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 elevated vaginal fluid pH... and the presence of volatile vaginal fluid amines." This involves testing a sample taken from the body (vaginal fluid) in vitro (outside the body).
  • Device Description: The description further clarifies that it contains "two qualitative, colorimetric tests for use in the characterization of a vaginal fluid sample." This confirms it's a test performed on a biological sample.
  • Anatomical Site: The anatomical site is listed as "Vaginal fluid," which is a biological sample.

These points clearly align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition.

Device Description

pH Test: The pH test contains a colorimetric pH indicator, which produces a visual color change within one minute of sample application. When contacted with a vaginal fluid sample at or above pH 4.7, the pH test area produces a distinct greenish-blue plus sign against a vellow background and a greenish-blue procedural control dot in the test area. When contacted with a vaginal fluid sample lower than pH 4.7, the pH test produces only a greenish-blue procedural control dot, within one minute, against a yellow background in the test area. Any test that does not develop a procedural control dot is considered an invalid result.

Amines Test: The QuickVue Advance Amines gll test contains a colorimetric pH indicator, which produces a visual color change within one minute of sample application. The test employs a film of BCG in the yellow test area that is surrounded by a thick black ring covered with a dried alkali analogous to the potassium hydroxide (KOH) used to perform the whiff test. The amines test area produces a distinct greenish-blue plus sign against a yellow background within one minute and a greenish-blue procedural control dot in the test area when contacted with a vaginal fluid specimen containing volatile amines at concentrations above 0.5 mM. When contacted with a vaginal fluid specimen that does not contain alkali volatilizable amines test produces a greenishblue procedural control dot against a yellow background in the test area (within one minute). Any test that does not develop a procedural control dot is considered an invalid result.

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

Numerous studies were undertaken to validate the performance characteristics and the substantial equivalence of the QuickVue Advance pH and Amines gll test. These studies included the following:

  • The test was shown to have excellent intra- and inter-assay precision.
  • Lot-to-lot consistency analyses showed the test to be reproducibly manufacturable.
  • Potentially interfering substances were shown not to interfere.
  • A multi-center field clinical study was conducted. Sensitivity, specificity and overall accuracy relative to the Amsel criteria with resolution by Gram stain were calculated.
  • Physicians' Office Laboratory studies were conducted to show that physician office personnel could perform the test accurately and reproducibly. Testing was performed at three geographically distinct sites in the United States.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Sensitivity, specificity and overall accuracy relative to the Amsel criteria with resolution by Gram stain were calculated.

SUMMARY OF SAFETY AND EFFECTIVENESS XI.

Product:

QuickVue® Advance pH and Amines gll test

Manufacturer:

QUIDEL Corporation 10165 McKellar Court San Diego, California 92121 U.S.A.

Device Classification:

Urinary pH (nonquantitative) test system 21 CFR 862.1550 Class I

Intended Use:

The QuickVue Advance pH and Amines all test contains two qualitative, colorimetric tests for use in the characterization of a vaginal fluid sample: (1) a pH test that differentiates vaqinal fluid pH 4.7; and (2) a test that detects alkali volatilizable amines in vaginal fluid. The test is intended for use by health care professionals as an aid in the diagnosis of bacterial vaginosis.

Principles of the Test:

pH Test: The pH test contains a colorimetric pH indicator, which produces a visual color change within one minute of sample application. When contacted with a vaginal fluid sample at or above pH 4.7, the pH test area produces a distinct greenish-blue plus sign against a vellow background and a greenish-blue procedural control dot in the test area. When contacted with a vaginal fluid sample lower than pH 4.7, the pH test produces only a greenish-blue procedural control dot, within one minute, against a yellow background in the test area. Any test that does not develop a procedural control dot is considered an invalid result.

Amines Test: The QuickVue Advance Amines gll test contains a colorimetric pH indicator, which produces a visual color change within one minute of sample application. The test employs a film of BCG in the yellow test area that is surrounded by a thick black ring covered with a dried alkali analogous to the potassium hydroxide (KOH) used to perform the whiff test. The amines test area produces a distinct greenish-blue plus sign against a yellow background within one minute and a greenish-blue procedural control dot in the test area when contacted with a vaginal fluid specimen containing volatile amines at concentrations above 0.5 mM. When contacted with a vaginal fluid specimen that does not contain alkali volatilizable amines test produces a greenishblue procedural control dot against a yellow background in the test area (within one minute). Any test that does not develop a procedural control dot is considered an invalid result.

Safety and Effectiveness:

Numerous studies were undertaken to validate the performance characteristics and the substantial equivalence of the QuickVue Advance pH and Amines gll test. These studies included the following:

  • The test was shown to have excellent intra- and inter-assay precision. 1.
  • Lot-to-lot consistency analyses showed the test to be reproducibly manufacturable. 2.
  • Potentially interfering substances were shown not to interfere. ന്
  • A multi-center field clinical study was conducted. Sensitivity, specificity and overall 4. accuracy relative to the Amsel criteria with resolution by Gram stain were calculated.
  • ம் Physicians' Office Laboratory studies were conducted to show that physician office personnel could perform the test accurately and reproducibly. Testing was performed at three geographically distinct sites in the United States.

Conclusion:

These studies demonstrated the substantial equivalence of the QuickVue Advance pH and Amines gll test to existing products already marketed, including the FemExam TestCard test [510(k) K962718], also sold under the brand name QuickVue Advance pH and Amines test. They further demonstrated the suitability of the product for laboratory and professional use. Such studies are a critical element in establishing the fundamental safety and effectiveness of the product and its appropriateness for commercial distribution.
