Indications for Use

The pH and Amines External Control Set is intended for use as external controls in accordance with the package insert instructions for the QuickVue® Advance pH and Amines test or the FemExam® pH and Amines TestCard™. When following these instructions, the Controls are to be used in the same manner as a patient swab specimen. For use by healthcare professionals.

Device Story

External control set for QuickVue Advance pH and Amines test and FemExam pH and Amines TestCard; consists of positive control (buffered solution, pH > 4.7, volatile amines > 0.5mM) and negative control (buffered solution, pH < 4.7, volatile amines < 0.5mM). Used by healthcare professionals in clinical settings; controls processed like patient swab specimens. Provides expected color response for positive/negative results; verifies test system performance and operator technique. Benefits patient by ensuring accuracy and reliability of diagnostic test results.

Clinical Evidence

Bench testing only. Studies evaluated inter- and intra-assay precision and lot-to-lot consistency to demonstrate reliable performance and reproducibility of the controls when used with the QuickVue Advance pH and Amines test and FemExam pH and Amines TestCard.

Technological Characteristics

Buffered aqueous solutions containing volatile amines. Positive control: pH > 4.7, amines > 0.5mM. Negative control: pH < 4.7, amines < 0.5mM. Formulated for use as external quality control specimens in diagnostic test cards.

Indications for Use

Indicated for use by healthcare professionals as external quality control material for the QuickVue Advance pH and Amines test and the FemExam pH and Amines TestCard to verify test and operator performance and aid in result interpretation.

Regulatory Classification

Identification

A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.

#### XI. Summary of Safety and Effectiveness

The following information as presented in the Premarket Notification [510(k)] for the pH and Amines External Control Set constitutes data supporting a substantially equivalent determination.

# Product:

pH and Amines External Control Set

# Manufacturer:

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

## Device Classification:

The device, pH and Amines External Control Set, is similar to other FDA-cleared devices which are used in test systems to demonstrate (verify) test performance. The pH and Amines External Control Set falls within the classification of 21 CFR 862.1660.

The Food and Drug Administration has proposed that Quality Control Material (assayed or unassayed) be classified as Class I.

### Intended Use:

The pH and Amines External Control Set is intended for use as external controls in accordance with the package insert instructions for the QuickVue® Advance pH and Amines test or the FemExam® pH and Amines TestCard™. When following these instructions, the Controls are to be used in the same manner as a patient swab specimen. For use by healthcare professionals.

### Principle of the Controls:

The Positive Control contains a buffered solution (pH > 4.7 and volatile amines > 0.5mM); the Negative Control contains a buffered solution (pH < 4.7 and volatile amines < 0.5 mM). The pH and Amines External Control Set will produce examples of the color response to be expected for negative and positive specimens when tested with the QuickVue Advance pH and Amines test or the FemExam pH and Amines TestCard. These controls are intended for use as external controls to aid in the interpretation of positive and negative test results and verify test and operator performance.

# Safety and Effectiveness:

Numerous studies were undertaken to document the performance characteristics and the substantial equivalence of the pH and Amines External Control Set to other commercially available products. These studies include the following:

- 1. The pH and Amines External Control Set was shown to be similar to other commercially available controls in terms of features and intended use.
- 2. Inter- and intra-assay precision analysis and lot-to-lot consistency demonstrated that the Controls could be manufactured reproducibility for reliable performance in the QuickVue Advance pH and Amines test or the FemExam pH and Amines TestCard.

# Conclusion:

These studies demonstrated the substantial equivalence of the pH and Amines External Control Set to existing products already marketed. 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.

Dear Ms. Weiner:

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 either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
