## Intended Use

FemLab is a biochemical assay intended for use as a screening test for nitrites, blood, protein, leukocytes and proline-iminopeptidase in vaginal fluid samples. It is indicated for use as an aid in the presumptive diagnosis of vaginitis or urethritis and should be used in conjunction with laboratory tests such as Gram stain, microscopic examination, culture and KOH test. The FemLab Vaginitis Test Kit is for professional and laboratory use only.

## Device Story

FemLab Vaginitis Test Kit is a hand-held, professional-use diagnostic cassette; features seven sample application zones on a plastic platform. Input: vaginal fluid collected via three-step swab procedure; two samples applied directly to test zones; third sample diluted in buffer. Principle: chemical/biological indicators undergo color change upon contact with specific analytes (pH, proline-iminopeptidase, nitrite, blood, protein, leukocyte). Output: visual color change on test zones indicating positive/negative results. Used in laboratory/clinical settings by professionals to aid in presumptive diagnosis of vaginitis or urethritis; results used alongside Gram stain, culture, and microscopic examination to inform clinical decision-making.

## Clinical Evidence

Multi-center study of 300 post-pubertal women. Comparison against traditional laboratory methods (pH, proline-iminopeptidase, wet mount, culture). Results: 18 true positives, 266 true negatives, 9 false positives, 7 false negatives. Overall agreement: 94.6%.

## Technological Characteristics

Hand-held plastic cassette with seven test zones. Employs chemical/biological colorimetric indicators. Qualitative detection of vaginal pH (≥4.7), proline-iminopeptidase (≥20 pm/m), nitrite (≥0.06 mg/dL), blood (≥0.015 mg/dL), protein (≥1.5 mg/dL), and leukocyte (≥5 cells/h). Uses filter membrane technology. Manual operation; no electronic components or software.

## Regulatory Identification

A microorganism differentiation and identification device is a device intended for medical purposes that consists of one or more components, such as differential culture media, biochemical reagents, and paper discs or paper strips impregnated with test reagents, that are usually contained in individual compartments and used to differentiate and identify selected microorganisms. The device aids in the diagnosis of disease.
