VS-SENSE OTC - a self-use swab

VS-SENSE OTCTM is a self-use swab, incorporating an acidity indicator coated tip. It is an alternative method to the VI-SENSE panty-liner designed to be used by women with the same symptoms described in the VI-SENSE section. It provides a higher level of performance than the VI-SENSE panty-liner (see statistics below).

How to use:
While holding the handle, insert the VS-SENSE OTC swab into the vagina. Rotate the swab several times and pull out. Observe the tip for color change or color stain. A Green or Blue stain indicates abnormal acidity, suggesting bacterial or Trichmonas infection. In such a case, consult your gynecologist or healthcare professional to obtain treatment. A Yellow color (no color change) suggests fungal infection, for which anti-fungal treatments are available OTC in pharmacies (over the counter, without prescription) that can be used for simple self treatment.
